The Sugars Will Eventually be Exported Transporters (SWEET) family plays a crucial role in the carbohydrate distribution, phloem loading, and stress response of plants, yet the evolutionary characteristics and functional diversification of SWEET genes in the endangered timber species Phoebe bournei (Hemsl.) Yen C. Yang remain largely unexplored. In this study, 21 PbSWEET genes were identified and classified into four subfamilies (A-D). Subfamily A exhibited a unique lineage expansion, mainly driven by tandem and segmental duplications. The nonsynonymous-to-synonymous substitution ratio (Ka/Ks) values of all duplicate gene pairs were all less than 1, indicating a strong selective suppression effect; consistent with this evolutionary constraint, the majority of PbSWEET proteins harbor the conserved Medicago truncatula Nodulin 3/saliva (MtN3_slv) domain, with only a few exceptions lacking a complete version. Promoter and hormone response analyses revealed that under abscisic acid (ABA) stress, PbSWEET4 exhibited an immediate burst, whereas PbSWEET10 showed a delayed burst. Physiological data indicated that soluble sugars may be more dominant osmolytes than proline (Pro), a pattern that points to a potential carbon-centric regulatory strategy. PbSWEET4 showed an early burst before sugar/oxidative peaks, suggesting a possible non-canonical signaling role, whereas PbSWEET10 exhibited a late increase coinciding with sugar/malondialdehyde (MDA) peaks, suggesting potential involvement in sugar redistribution. Under methyl jasmonate (MeJA) treatment, PbSWEET10 was rapidly induced, yet sugar accumulation occurred only at 24 h, a temporal decoupling that suggests a possible transcription-metabolism decoupling. Collectively, these correlative patterns point to a possible dual-wave transcriptional mechanism and nominate PbSWEET10 as a candidate for stress response, though these inferences require functional validation.
Regular consumption of excess sugar is linked to nutrition-based diseases, including gut problems, Non-Alcoholic Fatty Liver Disease, and Type 2 Diabetes Mellitus. Increasing sweetness perception is a novel technique to decrease sugar consumption. This experiment compared the sweetness perception of sweetened and unsweetened almond milk in response to different virtual environments with music and visuals. Two music types, the classical song Goldberg Variations, BMV. 998-Variation 13 and a jazz song generated by AI were used. Additionally, fall and spring forest backgrounds were generated by the Blockade Labs 3D image generator. Each participant tasted sweetened and unsweetened almond milk in music-only, background-only, and combination music and background environments. Results revealed significant differences in sweetness ratings for music type (p = 0.015) and between milk types (p < 0.001). Viscosity rating differed significantly between backgrounds (p = 0.04) and by milk type (p < 0.001). Liking ratings varied significantly between backgrounds (p < 0.001) and between music genres (p = 0.011). The results suggest that altering music and background may be a strategy to change sweetness and viscosity perception in unsweetened beverages.
This study investigated the effects of drying method and ingredient form on the quality characteristics of tarhana enriched with purple sweet potato (Ipomoea batatas L.). Tarhana samples were formulated with purple sweet potato in two forms (puree and freeze-dried powder) at incorporation levels of 5% and 10%, and subjected to either traditional sun-drying or freeze-drying. The drying method emerged as the dominant factor influencing product quality. Freeze-dried samples exhibited significantly lower moisture content and water activity along with a highly porous microstructure, indicating favorable physicochemical characteristics associated with product stability. Purple sweet potato incorporation enriched the phenolic profile and improved antioxidant capacity, with greater retention observed under freeze-drying conditions, particularly in powder-based formulations. Microbiological analysis revealed that freeze-drying preserved higher populations of lactic acid bacteria while suppressing yeast and mold growth. Instrumental aroma analysis demonstrated a clear shift in volatile composition depending on processing conditions, with freeze-drying yielding a more favorable aroma profile compared to sun-drying. Freeze-drying was identified as a superior method for preserving bioactive compounds, microbial viability, and aroma quality in purple sweet potato-enriched tarhana. These findings highlight the functional potential of purple sweet potato as an ingredient in traditional fermented foods and provide a basis for the development of high-quality tarhana formulations.
Sweet potato chlorotic stunt virus (SPCSV) is a major pathogen that threatens sweet potato production. It frequently acts synergistically with other viruses, causing severe yield losses and quality decline. A rapid and efficient detection method is therefore essential for preventing and controlling the spread of this virus. Here, we developed a reverse transcription real-time fluorescence recombinase-aided amplification (RT-RAA) assay using human apurinic/apyrimidinic endonuclease 1 (hAPE1, designated as tool enzyme E10). This enzyme exhibits high AP endonuclease activity but extremely low exonuclease activity, so that amplification products remain intact rather than being degraded as commonly occurs with the traditionally used Exonuclease III (ExoIII), thereby preserving product integrity for subsequent analysis. The established RT-hAPE1-RAA assay for SPCSV can be completed within 10 minutes and has a sensitivity of 100 ag/μL, corresponding to approximately 26 copies/μL of a recombinant pUC57 plasmid (3,484 bp) containing a 774bp SPCSV coat protein gene. Gel electrophoresis confirmed that E10 preserved viral amplification fragments intact, whereas ExoIII caused significant degradation. When testing 43 field-collected sweet potato samples, the method demonstrated a sensitivity of 94.4% and a specificity of 100%, showing high concordance with RT-qPCR results . Furthermore, E10 maintained stable cleavage activity across diverse target sequences, indicating its broad applicability. This work provides a rapid, sensitive, and reliable tool for SPCSV detection and offers technical support for the on-site diagnosis of sweet potato viral diseases.
Cross-modal correspondence, a cross-sensory cognitive phenomenon, reveals the link between visual forms and taste experiences. Although research on Western alphabetic typography is extensive, the Chinese character system has received less attention. This study systematically examines Chinese typeface categories (Song, Hei, Yuan, and Calligraphic) and stroke thickness (bold, medium, thin) in a real packaging context. The effects on the expectancies of the five flavors-sour, sweet, bitter, spicy, and salty-were measured. The results showed a significant interaction effect between typeface category and stroke thickness for all five flavor dimensions. The rounded Yuan typeface with thin strokes tended toward sweetness. Bold Song typefaces tend toward bitterness or spiciness, while bold Hei typefaces tend toward saltiness. The Calligraphic typeface, with its complex visual features, is strongly associated with bitterness and spiciness only when paired with bold strokes. Sourness shows a reverse modulation pattern. These findings reveal that the visual features of Chinese typefaces shape gustatory crossmodal correspondences through interactive modulation rather than simple linear addition. This confirms the common cross-modal perceptual pattern of 'curvature-sweetness, angularity-non-sweetness' across Chinese and English writing systems while also reflecting the culturally specific patterns driven by Chinese typographic features (such as the bifeng structure at stroke terminals) and the unique phenomenon of cross-modal correspondence with spiciness. This provides an empirically grounded and culturally adaptive reference for the marketing application of Chinese typefaces in packaging contexts.
Sweet potato residue, a high-yield fibrous by-product generated during starch extraction processing, is abundant in insoluble dietary fiber (IDF) yet remains severely underutilized owing to its inherent limited functional characteristics. In this work, we adopted citric acid (CA) at gradient concentrations to modify the IDF extracted from sweet potato residue, and systematically investigated its potential as an efficient stabilizer for Pickering emulsions. CA treatment maintained the crystalline structure of IDF while increasing crystallinity and surface area, enhancing thermal stability, and decreasing particle size, without significantly altering functional groups. The modified IDF produced emulsions with shear-thinning behavior, with viscosity increasing with higher CA concentrations. CA-modified IDF exhibited improved emulsifying capacity and emulsion stability compared to unmodified IDF, although high CA concentrations diminished these enhancements. The resulting emulsions demonstrated superior viscoelastic properties and stability under centrifugal testing. These findings suggest that CA-modified IDF is a highly effective emulsifier for O/W emulsions, exhibiting excellent stability at 10%, 20%, and 30% CA concentrations, providing a sustainable approach to valorizing sweet potato residue for emulsifier applications.
Sweet sorghum, a high-quality forage and energy crop, is significantly affected by drought, the primary abiotic stress impacting its growth. Melatonin (MT) has emerged as a crucial signaling molecule in plant responses to abiotic stress. This study investigates the role of melatonin in enhancing drought tolerance in sweet sorghum, specifically using the 'Dali Shi' variety under polyethylene glycol (PEG)-induced drought conditions. Our findings demonstrate that exogenous melatonin application significantly increased proline content (by 27.76% and 5.95% under mild and moderate drought, respectively) while decreasing malondialdehyde (MDA) levels (by 18.33% and 35.18%, respectively). Melatonin also enhanced the accumulation of photosynthetic pigments, including chlorophyll b and total chlorophyll, and improved photosynthetic fluorescence parameters (Fv/Fm and ETR). Additionally, melatonin treatment improved root vitality, stimulated carbon and nitrogen metabolism, and increased antioxidant enzyme activity. Transcriptomic analysis revealed that differentially expressed genes were enriched in pathways related to carbon fixation, glycolysis/gluconeogenesis, nitrogen metabolism, antioxidant defense, and plant hormone signaling. Notably, melatonin upregulated key genes associated with these pathways and activated bHLH and MYB transcription factors. In conclusion, this study elucidates the mechanisms by which melatonin enhances sweet sorghum's drought tolerance, highlighting its potential as a practical approach for improving drought resistance in this crop.
Background: Di19 (drought-induced 19)proteins belong to the C2H2-type zinc-finger family and play a crucial role in regulating plant growth, developmental processes, hormone signal transduction, and abiotic stress adaptation. However, research on the Di19 gene family in sweet potato and its diploid relatives remains relatively limited. Methods: At the whole-genome level, members of the Di19 gene family in sweet potato (Ipomoea batatas, 2n = 6x = 90) and its two diploid relatives, Ipomoea trifida (2n = 2x = 30) and Ipomoea triloba (2n = 2x = 30) were systematically identified, and multi-dimensional bioinformatics analyses were carried out. Results: Seven Di19 genes were identified per species, with the family's overall evolutionary characteristics conserved. Some IbDi19s showed species-specific structural variations, mainly manifested as an increase in the number of exons, loss or substitution of conserved motifs. The expression patterns of Di19s of two diploid relatives are highly conserved. IbDi19s are mainly expressed in leaves and roots. Most members respond significantly to JA treatment, but hardly respond to IAA. The expression of IbDi19-1 was significantly up-regulated by 336-fold and 68-fold under GA3 and cold treatments, respectively. Based on bioinformatics and expression data, a hypothesis was proposed that IbDi19-1 may be involved in the regulation of low-temperature response and gibberellin signaling pathways. Conclusions: This study provides candidate genes and a theoretical basis for evolutionary analysis, stress-resistant molecular breeding of the Di19 gene family in sweet potato and its two diploid relatives.
ATP-binding cassette (ABC) transporters constitute one of the largest gene families in plants. These encoded transmembrane proteins rely on energy provided by ATP hydrolysis to facilitate the directional transport of diverse substrates, such as heavy metal (HM) ions, secondary metabolites, and phytohormones, playing a pivotal role in plant responses to HM stress. In this study, a systematic identification and expression analysis of the ABC gene family in sweet potato (Ipomoea batatas) was conducted at the whole-genome level. We comprehensively characterized the physicochemical properties, structural features, chromosomal distribution, and tissue-specific expression patterns of IbABC genes. Furthermore, their expression profiles under iron (Fe), aluminum (Al), zinc (Zn), and copper (Cu) stress were evaluated using RT-qPCR. The results demonstrated that most IbABC genes exhibited significant differential expression under HM stress. Notably, IbABCC14 was significantly upregulated under all four metal treatments (Fe, Al, Zn, and Cu) and showed high homology with phytochelatin transporters in Arabidopsis thaliana and Oryza sativa. This suggests that IbABCC14 may participate in HM detoxification by mediating vacuolar sequestration. By elucidating the expression patterns of the IbABC family under HM stress, this study identifies key candidate genes for breeding sweet potato varieties with enhanced HM tolerance.
The genus Capsicum is widely used worldwide for its culinary value and functional potential. The objective of this study was to evaluate the bioactive compounds, antioxidant and antimicrobial activity of sweet and hot pepper at different stages of ripeness. Six varieties of peppers at five stages of ripeness were analysed. Mineral parameters (Ca, Fe, Na, K, Mg) were determined by atomic absorption spectrophotometry, while bioactive compounds (vitamin C, organic acids, carotenoids, and phenols) were analysed by liquid chromatography. Antioxidant activity was evaluated using ABTS and DPPH assays, and antimicrobial activity was assessed by minimum inhibitory concentration against bacteria and yeasts. Multivariate analyses (PCA and heatmap) were carried out at a significance level of p < 0.05. The results showed that genotype was the main determinant of variability, surpassing the effect of ripeness. Potassium was the predominant mineral (3431.5 mg/100 g DW) in Malagueta chilli M5. Variety-specific peaks were identified, notably vitamin C in Habanero chilli (M3) (10,319.5 mg/100 g DW), capsaicin in Malagueta chilli (M5) (1949.8 mg/100 g DW), and carotenoids in Orange medium peppers (M5) (9495.8 mg/100 g DW). Antioxidant activity was higher in hot varieties (41.3 mmol ET/100 g DW in Habanero chilli (M2) by DPPH), while antimicrobial activity varied against Escherichia coli (2.6 mg/mL in Yellow medium peppers (M4)), Staphylococcus aureus (5.2 mg/mL in Orange medium pepper), and Streptococcus mutans (2.0 mg/mL in Jalapeño chilli), with low MIC values. Multivariate analyses confirmed that chemical and biological variability is primarily structured by genotype.
Sweet's syndrome (acute febrile neutrophilic dermatosis) is an inflammatory condition characterized by the abrupt onset of erythematous, oedematous plaques or nodules and a dense neutrophilic dermal infiltrate. Although usually associated with fever and tender lesions on the face and upper extremities, its clinical spectrum is broad, and atypical presentations may pose diagnostic challenges. We report the case of a 50-year-old female patient who presented with an acute eruption of widespread, annular, erythematous, and oedematous plaques predominantly involving the trunk and extremities, accompanied by severe pruritus. The patient denied fever or other systemic symptoms. Laboratory investigations demonstrated marked leukocytosis with neutrophilia and elevated inflammatory markers. An extensive infectious, immunological, and malignancy workup was unremarkable. Histopathological examination revealed a dense neutrophilic dermal infiltrate with leukocytoclasia in the absence of true vasculitis, consistent with Sweet's syndrome. Direct immunofluorescence was negative. The patient reported a history of similar episodic eruptions over two decades, often temporally associated with respiratory infections. Systemic glucocorticoid therapy led to rapid clinical improvement and normalization of inflammatory parameters, with complete resolution at follow-up. This case highlights the clinical heterogeneity of Sweet's syndrome, demonstrating that prominent pruritus, truncal predominance, and afebrile presentation may occur. Recognition of atypical manifestations is essential to avoid misdiagnosis, particularly with urticarial or allergic disorders. Thorough evaluation for associated systemic disease and careful documentation of recurrent patterns remain crucial. Early histopathological confirmation and prompt initiation of appropriate therapy enable rapid disease control and favourable outcomes.
In May 2023, Ghana implemented a 20% ad valorem tax on bottled water and sweet beverages (SBs), replacing a 17.5% tax; sachet water remained untaxed. The effect on low-income consumers' purchasing decisions and consumption patterns remains poorly understood. We aimed to explore factors influencing water and SB purchasing behaviours among low-income households in four peri-urban Accra communities. This study employed a convergent parallel mixed-methods design. Four focus group discussions (n = 36) and a cross-sectional survey (n = 43) were conducted among purposively sampled household primary shoppers in early 2025 across Oyarifa, Teiman, Kweiman, and Danfa. Data were analysed thematically and descriptively. Of 43 participants, 67% were female and 65% had junior high school education. Water insecurity was common (60%), and sachet water was the main drinking source (77%). SB purchasing was driven by taste and convenience, while sachet water choices were linked to perceived safety, price, and availability. Tax awareness was moderate (56%); many perceived bottled water taxation as unfair and reported intentions to switch to cheaper local alternatives. Limited tax awareness and perceived inequities suggest the need for policy refinements to better align fiscal measures with public health objectives.
Three-dimensional (3D) food printing, a relatively new food-processing method, was explored using gelatinized sweet potato starch (SPS) as a food ink. Prior to the production of intricate 3D shapes, this study focused on the precise extrusion of filaments, specifically the optimization of the printing conditions for nozzle diameters of 1.5 and 4.0 mm to produce filaments with an acceptable appearance and size. The rheological and mechanical properties of the (SPS) sol were also determined to describe the extrudability and shape retention of the food materials. The optimization process employed the Response Surface Methodology (RSM) and a desirability function to generate mathematical models of the width and height of the filaments as functions of the moisture content, the print temperature, and the print speed. The generated mathematical models were used to determine the optimum printing conditions. Hence, for the 1.5 mm nozzle, the optimum condition was at 82% moisture content, 57 °C print temperature, and 10 mm/s print speed, with a desirability of 0.842. In contrast, for the 4.0 mm nozzle, the optimum condition was at 82.3% moisture content, 50 °C print temperature, and 5 mm/s print speed, with a desirability of 0.911. The optimized filaments are expected to be used in 3D food printing to create 3D shapes.
Japonica rice offers high cost-effectiveness and yield, with the potential to replace glutinous rice in Chinese sweet rice wine (CSRW) brewing. It can be classified into aromatic and non-aromatic types, but whether different varieties cause flavor and metabolite differences in CSRW remains unclear. In this study, glutinous rice (GR), three aromatic japonica varieties (CS-217, HXR-450, SXJ-1018), and two non-aromatic varieties (TA-1, HR-1212) were used as raw materials. The qualities of different CSRWs were evaluated through physicochemical indices, sensory evaluation, phenolic and flavonoid contents, antioxidant capacities, HS-GC-IMS, and UPLC-MS/MS. The results showed that CS-217 displayed the highest total acid content, along with excellent overall sensory evaluation, total phenolic content, and antioxidant capacity. A total of 28 VOCs were identified by HS-GC-IMS, among which 13 compounds with VIP ≥ 1, including butyl isobutyrate, butyl acetate, and ethyl pentanoate, were identified as key flavor discriminant factors. Additionally, 2501 non-volatile metabolites were identified, and five key metabolic pathways were revealed. These pathways synergistically regulate CSRW flavor and nutritional quality. Different japonica rice varieties exhibited respective advantages in CSRW quality indicators, providing a basis for the diversification of raw materials in CSRW production.
The leaf miner (Liriomyza huidobrensis) represents a critical threat to sweet potato production, causing irreversible damage that traditional visual inspection fails to mitigate efficiently due to its subjectivity and slowness. The objective of the present study was to automate the detection of this pest through image analysis using deep learning models. Methodologically, the dataset "camote_minador" was constructed and annotated, comprising 751 images collected from fields in Lambayeque, Peru, to which dynamic data augmentation techniques were applied to ensure training variability. The performance of the YOLOv8s and YOLOv11s architectures was comparatively evaluated under standardized hyperparameter configurations. The results demonstrated the technical superiority of the YOLOv11s model, which achieved a Precision of 73.20%, a Recall of 66.72%, and a mAP@50 of 71.63%, outperforming its predecessor and evidencing a greater ability to discriminate between pest galleries and background noise. Furthermore, the operational feasibility of a mobile prototype based on Tensor Flow Lite for mid-range devices was established. It is concluded that the implementation of optimized architectures such as YOLOv11s constitutes an effective, accessible, and scalable technological solution to strengthen phytosanitary monitoring in the agricultural sector.
Agri-food by-products such as sweet potato peel (SP) represent a sustainable and valuable source of bioactive compounds for improving gluten-free (GF) foods. This study evaluated the nutritional and functional impact of incorporating SP at 8% and 16%, either untreated or ultrasound-assisted extraction (UAE)-treated, into GF brownies. An untargeted metabolomics approach combined with chemometrics was applied to characterize phytochemical modulation after in vitro digestion of the brownies, while antioxidant and anti-inflammatory effects were assessed using RAW264.7 macrophages. SP incorporation increased the dietary fiber (reaching a content of 7.86%) and glycosylated flavonoid content in reformulated brownies, leading to a reduction of inflammatory markers in the cellular model. Sensory evaluation showed that SP addition did not significantly affect texture-related attributes or extract-related perception. In contrast, UAE acted as an efficient extraction strategy, enhancing terpenoid-like compounds and total phenolic content (TPC), reaching values of 401.97 mg GAE 100 g-1 after 16% incorporation. Overall, combining SP valorization with UAE represents a promising strategy to develop nutritionally enhanced GF products, providing a foodomics-based framework for next-generation functional bakery products.
Several studies on diet and microbiome have predominantly focused on the gut microbiome. However, much of the salivary microbiome remains unexplored. This study examined the influence of Thai desserts with varying glycemic indices on the salivary microbiome. A total of 30 healthy adults aged 18-45 years were enrolled in a randomized trial and allocated to one of three intervention groups, with each receiving a culturally specific Thai dessert standardardized to provide 50 g of available carbohydrates: Phetchaburi's Custard Cake (PCC; low-GI, 192 g), Saraburi's Curry Puff (SCP; medium-GI, 98 g), or Lampang's Crispy Rice Cracker (LCRC; high-GI, 68 g). Salivary and dessert microbiome compositions were characterized at baseline and 24 h post-intervention using 16S rRNA sequencing to evaluate bacterial diversity and relative abundance across multiple taxonomic levels. Firmicutes were highly abundant (over 76%) in all Thai desserts tested. Proteobacteria were found in both SCP (15.1 ± 6.6%) and LCRC (6.5 ± 3.4%). Actinobacteriota was slightly higher in the high-GI group (6.3 ± 3.1%) compared to the medium-GI group (3.0 ± 2.2%). Bacillus was dominant in PCC, while Streptococcus, Carnobacterium, and Clostridium sensu stricto 1 were prevalent in SCP. Anoxybacillus, Clostridium sensu stricto 12, Terrilactibacillus, Geobacillus, and Weissella were found in LCRC. Desserts with different types of glycemic index showed modest short-term changes in the relative abundance of some salivary bacteria. Notably, Porphyromonas showed a relative increase in the high-GI group compared to the low-GI group (1.8 [0.3, 4.0] vs. -1.9 [-3.2, 0.8], p < 0.05), while Streptococcus, saccharolytic bacteria, slightly increased in both the high-GI and medium-GI groups. Prevotella showed a slight relative decrease in the low-GI group. Although these microorganisms have been previously associated with dysbiosis and periodontitis in longer-term studies, the clinical relevance of these short-term compositional changes remains unclear and should be interpreted with caution. These preliminary findings suggest that local Thai desserts with varying GIs may be associated with transient shifts in salivary microbiota composition; however, whether such changes contribute to dysbiosis or adverse oral health outcomes requires further investigation through longitudinal studies with larger sample sizes.
Women from racially and ethnically minoritized communities experience cardiometabolic health disparities. Insufficient sleep and poor sleep quality are common and potentially modifiable factors that impact cardiometabolic health; however, women face unique challenges to sleep. A bi-directional community-integrated approach is used as a foundation to learn more about sleep in under-researched populations of Utah, resulting in a study approach that is both effective and rigorous. We present the protocol for community integration and development of focus groups among female community health workers who represent the four communities participating in this study: African Immigrant, Black/African American, Native Hawaiian/Pacific Islander, and Latina. We describe establishing relationships, initiating the project, and preparing and conducting data collection, analysis, and dissemination plans. We anticipate the results of this project will provide unique perspectives about sleep in the participating communities, based on the experience of community health workers as community members and trusted leaders of their communities. This project continues an ongoing partnership between community health workers and academic researchers focused on reducing disparities in cardiometabolic disorders. The results of this project will lead to the identification of future research questions, outreach/education efforts, and development of a plan for future interventions among diverse racial and ethnic groups in our community.

The sweet potato weevil, Cylas formicarius (Fabricius) (Coleoptera: Brentidae), is one of the most destructive pests of sweet potato [Ipomoea batatas (L.) Lam.] crops worldwide. Current management of the sweet potato weevil relies heavily on conventional pesticides, raising concerns about pesticide residues, environmental impacts, and the development of pesticide resistance. This study evaluated the effects of seven essential oils (EOs): eucalyptus (Eucalyptus globulus), garlic (Allium sativum), marigold (Calendula officinalis), mustard seed (Sinapis alba), peppermint (Mentha piperita), rosemary (Rosmarinus officinalis), and thyme (Thymus gobicus) against different life stages of C. formicarius under laboratory conditions. Feeding activity, oviposition, larval mortality, pupal mortality, and adult survival were evaluated using EO concentrations of 1%, 5%, and 10%, with acetone and distilled water as control treatments. Each treatment consisted of six replicates, with 10 insects per replicate. Statistical analyses were performed using logistic regression models with a binomial distribution. Significant effects of oil type and concentration were observed as lethal to weevil larval and pupal stages. Similarly, the feeding and oviposition were significantly impacted (p < 0.0001). Peppermint oil exhibited the highest efficacy, causing complete or near-complete mortality of second- and third-instar larvae and pupae at 10%. This also substantially reduced adult survival, feeding activity, and oviposition. Rosemary, thyme, and eucalyptus, at higher concentrations. Most oils almost completely suppressed oviposition. These findings demonstrate that plant-derived essential oils (EOs) exhibit significant insecticidal activity against Cylas formicarius, indicating their promise as sustainable tools for integrated pest management programs in sweet potato production systems.
