An invasive insect, chilli thrips, Scirtothrips dorsalis Hood (Thysanoptera: Thripidae), has emerged as a major strawberry pest, causing considerable yield and revenue loss in recent years. Pesticide application is the leading control option but is not always recommended due to resistance development. Host plant resistance (HPR) can be a novel option to manage S. dorsalis sustainably. Four commercial cultivars, 'Florida Brilliance', 'Florida Medallion FL16.30-128', 'Sweet Sensation 'Florida127', and 'Florida Pearl FL16.78-109', were evaluated for their performance in the 2021-2022 field season under the natural population of S. dorsalis. In 2022-2023 and 2023-2024, 3 more cultivars, 'Strawberry Festival', 'Florida Radiance', and 'Florida Beauty', were added to this list. Twenty bare-root strawberry transplants were planted in each field plot, and each cultivar was replicated 8 times in a randomized complete block design. Damage on trifoliate, number of adults and larval S. dorsalis on trifoliate, number of flowers, and marketable fruit yield were assessed for each cultivar. Results revealed that 'Florida Pearl 109' had the highest insect count and damage index of all 3 year. 'Strawberry Festival' also showed the same trend after its introduction in the second year. 'Florida Brilliance' and 'Sweet Sensation' had the lowest damage index, lowest adult insect count, and higher marketable yield compared to 'Florida Pearl 109' and 'Strawberry Festival'. Therefore, utilizing resistant cultivars can be an effective tool for managing S. dorsalis in the field.</p>","PeriodicalId":94077,"journal":{"name":"Journal of economic entomology","volume":" ","pages":"816-825"},"PeriodicalIF":0.0,"publicationDate":"2025-04-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12034312/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143559439","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Discrepancies between product performance in laboratory and in-home studies are concerning and suggest that laboratory assays alone might not be indicative of the potential for control, especially in the context of the more complex home environment.

A potential approach for enhancing LLIN efficacy is the use of insecticide synergists to inhibit detoxification enzymes and exacerbate the effects of pyrethroids. Here, we evaluated the synergistic properties of 3 detoxification enzyme inhibitors-piperonyl butoxide (PBO), diethyl maleate (DEM), and triphenyl phosphate (TPP)-with LLIN against the red flour beetle Tribolium castaneum (Herbst), and the lesser grain borer Rhyzopertha dominica (Fabricius).

To investigate the effects of dimethoate treatment on the gut microorganisms and physiological functions of B. mori, 16S rRNA sequencing was used to analyzed the composition and structure of the gut microbiota. This study investigated their role in enhancing silkworm resistance by screening dominant populations after dimethoate treatment. The results indicated that dimethoate did not alter the composition of the dominant gut bacterial groups in silkworm; however, it significantly increased the abundance of the gut bacteria Methylobacterium and Aureimonas, and decreased the abundance of Enterobacterales, Bifidobacterium, Blautia, Collinsella, Faecalibacterium, and Prevotella. Eleven strains of dimethoate-resistant bacteria were selected through in vitro culture, all of which were unable to grow when dimethoate was used as a carbon source. Additionally, a germ-free silkworm model was established to assess detoxifying enzyme activity in the midgut.

The study investigated the main location of adult whiteflies relative to plant nodes (stem points where leaves or branches emerge), population variation within and between canopies, whitefly density variability across fields, the impact of dense nodes on overall canopy populations, and the feasibility of using machine learning for prediction. Daily scouting was conducted on 64 non-pesticide cotton plants, focusing on all leaves of a node with the highest whitefly counts. A linear mixed-effect model assessed distribution over time, and machine-learning model selection identified a suitable forecasting model for the entire canopy whitefly population. Findings showed that the top 3 to 5 nodes are key habitats, with a single node potentially accounting for 44.4% of the full canopy whitefly population. The Bagging Ensemble Artificial Neural Network Regression model accurately predicted canopy populations (R² = 85.57), with consistency between actual and predicted counts (P-value > 0.05).
