Entomopathogenic fungi (EPF) have gained attention as alternatives to conventional insecticides for pest management. The brown plant hopper (<i>Nilaparvata lugens</i>), a major threat to rice crops worldwide, has shown increasing resistance to insecticides due to overuse, creating an urgent need for non-chemical, environmentally friendly, safe and sustainable alternatives for BPH control. The biodiversity-rich North-East region of India holds untapped potential for discovering new, effective strains of EPF. This study was therefore conducted to examine the diversity of EPF in this region and assess their effectiveness against BPH for pest control. The primary objective was to evaluate the pathogenicity of indigenous EPF isolates from soil on BPH. Laboratory and polyhouse tests were conducted, beginning with eight <i>Beauveria bassiana</i> isolates in the laboratory, with the top three isolates moving to polyhouse trials. Preliminary findings showed that CCPR-Bb1 achieved the highest mortality rates, with 93.33% in laboratory conditions and 91.67% in polyhouse conditions against BPH. Temperature assessments indicated that 25°C was optimal for radial growth and sporulation across most isolates. Additionally, safety tests examined the effects of EPF isolates on <i>Trichogramma chilonis</i>, <i>Chrysoperla zastrowi sillemi</i> and <i>Apis cerana indica</i>. Results demonstrated that, at lower concentrations, these pathogens were generally safe for beneficial organisms, posing minimal risk. These EPF strains have the potential to aid farmers in reducing pesticide use, promoting environmental sustainability and serving as vital elements in integrated pest management (IPM) strategies.</p>\u0000 </div>","PeriodicalId":14987,"journal":{"name":"Journal of Applied Entomology","volume":"149 8","pages":"1270-1278"},"PeriodicalIF":2.0,"publicationDate":"2025-06-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144767364","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In the raspberry crop, there were no observed impacts of baits with insecticides on the abundance of insect pollinators or natural enemies compared to the full foliar applications of insecticides.

However, a few recent studies have reported effective pollination by ants both in wild plants and crops, although their potential as pollinators is still underexplored. In this study, we address the potential role of ants as pollinators of agroecological crops in NW Patagonia. We visited 25 agroecological orchards to identify crops whose flowers were visited by ants, the ant species involved, their behaviour during floral visits, and the number of legitimate visits. Additionally, we quantified ant pollen loads and the effect of ant body secretions on pollen germination. We recorded visits from <i>Dorymyrmex tener</i>, <i>D. wolffhuegeli</i>, <i>Brachymyrmex patagonicus</i>, <i>Lasiophanes picinus</i> and <i>Solenopsis richteri</i> to the flowers of 10 out of 47 crops. Ants were mainly legitimate visitors to small and open flowers, and primarily nectar thieves of larger flowers, with <i>D. tener</i> being the most frequent species. All ant species presented pollen loads from the visited crops, and contact with ant bodies reduced but did not completely suppress pollen germination in most crops. We found that ants visit the flowers of different crops in the region, and that their potential as pollinators depends both on the crop and the ant species involved, with higher chances of effective pollination by generalist and abundant ants, and crops with small and open flowers. This study contributes to understanding the role of ants in food production, which is especially relevant in the context of increasing environmental degradation and the pollination crisis.</p>\u0000 </div>","PeriodicalId":14987,"journal":{"name":"Journal of Applied Entomology","volume":"149 8","pages":"1237-1247"},"PeriodicalIF":2.0,"publicationDate":"2025-05-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144767972","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

All larvae collected were identified via DNA barcoding and subjected to 16S rRNA metabarcoding.
