We investigated the effect on eggs of several commercial insecticides whose active ingredients are registered to kill A. bungii adults or larvae by tree injection or spray. The ovicidal activity was evaluated using the corrected egg hatch rates based on the control (distilled water) after dipping pieces of cardboard, on which eggs were deposited, in liquid insecticide solutions for 10 sec. The egg-dipping tests revealed highly effective ovicidal activity in the following insecticides: more than 8000 ppm for fenitrothion, 1000 ppm for acetamiprid, 400 ppm for clothianidin, and 500 ppm for dinotefuran (corrected egg-hatch rates of approximately less than 5%). In terms of current registration in Japan, only fenitrothion (SUMIPAIN emulsion) and acetamiprid (MATSUGREEN liquid solution 2) by trunk spraying during the A. bungii reproductive period are adulticidal insecticide candidates with preventive potential through incidental ovicidal activity.","PeriodicalId":16712,"journal":{"name":"Journal of Pesticide Science","volume":"50 1","pages":"1-8"},"PeriodicalIF":1.5,"publicationDate":"2025-02-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11911499/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143657562","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this study, we investigated its MoA systematically, using varying biochemical techniques. Since FLO-treated insects exhibited symptoms similar to those induced by respiratory inhibitors, we examined the effect of FLO on respiratory enzyme complexes using mitochondria isolated from different insects (housefly, diamondback moth, and western flower thrips). We found that FLO itself is not active; however, its deacylated metabolite, FloMet, specifically inhibits the activity of ubiquinol-cytochrome c oxidoreductase (complex III) in mitochondria at the nM level. Ligand binding assays and monitoring the reduction kinetics of cytochrome hemes b and c 1 clearly revealed that FloMet inhibits complex III by binding to the Qi site.","PeriodicalId":16712,"journal":{"name":"Journal of Pesticide Science","volume":"49 4","pages":"203-209"},"PeriodicalIF":1.5,"publicationDate":"2024-11-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11770135/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143059229","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To this end, we synthesized 11 derivatives and evaluated their antifungal activity. Among these derivatives, the aldehyde derivative exhibited superior antifungal potency as compared to 1, and some acyl derivatives were able to maintain the antifungal activity of 1 despite significant structural changes. From these results, it is found that the aldehyde derivative is one of the most promising fungicidal candidates, and the introduction of acyl groups could be utilized to create chemical probes for target-identification experiments.","PeriodicalId":16712,"journal":{"name":"Journal of Pesticide Science","volume":"49 4","pages":"224-231"},"PeriodicalIF":1.5,"publicationDate":"2024-11-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11770174/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143059390","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
