Yet, each colony begins with a single mating encounter between a female and a male. After seasonal dispersal flights, termite dealates walk to search for a mating partner and a nest site. This initial stage is critical for dispersal, infestation, and invasion success. However, the search dynamics and success of these walking termites remain poorly understood, especially under varying environmental conditions. In this study, I investigated mate-searching and post-pairing dispersal behaviors in <italic>Coptotermes formosanus</italic>, one of the most damaging subterranean termites, by reanalyzing observations in the experimental arena using a deep-learning posture tracking approach. I show that termites can walk an average of 23 m within 15 min, with estimated displacements up to 18.74 m. Nest-searching tandem pairs showed more directional and stable motion with higher dispersal potential than mate-searching single termites because of the movement coordination. Simulations parameterized by termite observations showed that urban light attraction greatly contributed to the pairing success of termites, even with a low termite population density. These findings suggest that simple movement rules and environmental cues can enhance mating encounters and dispersal, facilitating infestation and invasion. Comparative behavioral studies across termite species may link the movement ecology of termites with their pest status and invasive potential.","PeriodicalId":16736,"journal":{"name":"Journal of Pest Science","volume":"33 1","pages":""},"PeriodicalIF":4.8,"publicationDate":"2026-03-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147507813","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Baited traps are a common option to capture individual hornets, as they are easily developed and accessible. Nevertheless, their impact on non-target species is often pointed out as a main drawback. In this study, we evaluated the impact of artisanal and commercial traps and baits on non-target insects and assessed the effectiveness and selectiveness of alternative traps to reduce the negative impacts of baited traps. Results show that in most baited traps, more than 98.5% of captured insects are not <italic>V. v. nigrithorax,</italic> evidencing the need to increase traps’ selectiveness.

Unlike most of its relatives, the spotted-wing drosophila (<italic>Drosophila suzukii</italic>) lays eggs in ripening fruit, making it a serious and rapidly spreading agricultural pest worldwide. Spice plants produce volatiles that repel many insects, presenting potential sources of behavioural modulators for <italic>D. suzukii</italic>. Here, we examined whether volatiles from clove (Syzygium aromaticum) affect adult behaviour and offspring performance in <italic>D. suzukii</italic>. Behavioural assays revealed strong aversion: adults avoided grapes treated with clove extract, and gravid females laid significantly fewer eggs on treated fruit in both no-choice and choice assays. Clove exposure also reduced fitness, resulting in slower larval growth, lower adult weight, decreased emergence rate, and shortened lifespan. Gas chromatography–mass spectrometry analyses identified eugenol as the predominant volatile. Synthetic eugenol elicited strong avoidance across multiple host fruits, including apple, banana, blueberry, guava, mango, orange, papaya, raspberry, strawberry, and tomato. Molecular docking and single-sensillum recordings indicated that eugenol binds most strongly to DsuzOR88a and DsuzOR69aA odorant receptors. Cheminformatic screening of 1000 eugenol analogues revealed several structural variants predicted to interact strongly with OR88a, providing additional candidate repellents. By integrating behavioural, analytical chemistry, electrophysiology, and cheminformatics, our study shows that clove, through its major volatile eugenol, modulates host choice and reduces offspring performance in <italic>D. suzukii</italic>. These results highlight the ecological role of plant-derived volatiles in insect–plant interactions and support eugenol as a promising natural compound for sustainable fruit pest management.","PeriodicalId":16736,"journal":{"name":"Journal of Pest Science","volume":"90 1","pages":""},"PeriodicalIF":4.8,"publicationDate":"2026-03-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147507811","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Yet, across many systems, information on taxonomic composition, spatiotemporal dynamics, and sensitivity of herbivore groups to crop management is sparse. In perennial tree crops, Auchenorrhyncha (Hemiptera) are abundant herbivores, notable for causing feeding damage and transmitting plant pathogens. Here, to strengthen the ecological understanding of Auchenorrhyncha activity in managed tree systems, we tracked the seasonal abundance and within-canopy distribution of Auchenorrhyncha in a mature pecan (<italic>Carya illinoinensis</italic>) orchard over two seasons and evaluated how these patterns interact with common canopy management interventions: hedge pruning and calendar-based pesticide applications of insecticide and fungicide. We collected 5882 Auchenorrhyncha, representing seven families. The assemblage was dominated by Cicadellidae, with over 95% of individuals belonging to the subfamily Typhlocybinae. Auchenorrhyncha abundance increased from June to September, and the lower canopy consistently harbored fewer insects. Calendar-based pesticide applications reduced community abundance, although effects varied across dates and canopy location, highlighting potential spatial constraints of pesticide use in tall trees. In contrast, hedge pruning significantly increased Auchenorrhyncha abundance, independently of pesticide use or canopy location. This study not only establishes a baseline for the taxa composition and spatiotemporal activity of Auchenorrhyncha in pecan systems but also advances our understanding of how common farming practices interact with herbivore community patterns. Together, these findings support the refinement of more ecologically grounded, spatially informed strategies for pest management in pecan and other tree-based systems.","PeriodicalId":16736,"journal":{"name":"Journal of Pest Science","volume":"90 1","pages":""},"PeriodicalIF":4.8,"publicationDate":"2026-03-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147507812","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The traditional ‘Foliage Protection Strategy’ (FPS) focuses on temporarily reducing defoliation and tree mortality in high-value stands, allowing outbreaks to progress naturally in surrounding areas. The ‘Early Intervention Strategy’ (EIS) is an adaptive, area-wide management approach that targets low-density “hotspots” to prevent outbreak growth and spread. We report findings from a 10-year case study (2015–2024) in Atlantic Canada assessing EIS effectiveness. EIS treatments consistently reduced population growth rates, resulting in a 12–67% reduction in hotspot areas compared to untreated areas. Crucially, this suppression curbed the rise and spread of the outbreak across northern New Brunswick, with negligible defoliation observed throughout the study period. By comparison, in a neighboring Quebec study area contemporaneously managed with FPS, the outbreak advanced normally, causing moderate to severe defoliation over ~ 1.7 million hectares by 2024. Moreover, EIS required ~ 80% less insecticide, with 66% of treated areas receiving treatment in only a single year, compared with just 15% under FPS. Our findings provide robust evidence for the effectiveness of EIS when implemented under suitable conditions, highlighting its potential as a proactive outbreak management approach.","PeriodicalId":16736,"journal":{"name":"Journal of Pest Science","volume":"6 1","pages":""},"PeriodicalIF":4.8,"publicationDate":"2026-02-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"146196672","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
