In present work, we reported identifying potential entomopathogen Bacillus cereus H1 B. H1) from their habitat was lethal adults following ingestion. First, isolated identified morbid pupae. Next, robustly arrested development fly progeny. Moreover, exerted adverse effect on survival locomotion adult flies. Mechanistically, disrupted intestinal homeostasis triggered oxidative innate immunity, resulting death within 5 days.

The commensal microbiota of the mosquito gut plays a complex role in determining vector competence for arboviruses. In this study, we identified bacterium from field Aedes albopictus mosquitoes named Rosenbergiella sp. YN46 ( Rosenbergiella_ YN46) that rendered refractory to infection with dengue and Zika viruses. Inoculation 1.6 × 10 3 colony forming units (CFUs) into A. effectively prevents viral infection. Mechanistically, secretes glucose dehydrogenase Ry GDH), which acidifies lumen fed mosquitoes, causing irreversible conformational changes flavivirus envelope protein prevent entry cells. semifield conditions, exhibits effective transstadial transmission blocks virus by newly emerged adult mosquitoes. prevalence is greater low-dengue areas (52.9 ~91.7%) than those dengue-endemic regions (0 ~6.7%). may offer an safe lead biocontrol.

Pathogenic microorganisms can impact the behavior and physiology of herbivores by direct or indirect means. This study demonstrated that yellow peach moth Conogethes punctiferalis larvae feeding on Penicillium-infected apples exhibited significantly longer body length weight parameters compared to control group. The sequencing gut 16S rRNA showed a significant increase in diversity abundance bacteria apples. Additionally, transcriptomic larval indicated upregulation genes related digestion cuticle formation after consuming Furthermore, enzyme activity assays revealed notable changes trypsin lipase activity. Consequently, these alterations microbiota structure, diversity, gene expression levels may underlie observed growth developmental variations C. mediated pathogenic microorganisms. holds theoretical significance for deeper understanding tripartite interaction among microorganisms, insects, plants as well development novel pest measures based microbiota.

Abstract Drosophila suzukii is a notorious pest which causes devastating damage to thin‐skinned fruits, and the larvae feed on fruit, causing extensive agricultural economic loss. The current application of insecticides manage this results in serious resistance environmental hazards, so an alternative strategy for D. biocontrol urgently needed. Here, we reported that entomopathogenic Bacillus cereus has potential . We isolated identified bacterial strain, B. H1, was detrimental fitness both progenies parents. robustly repelled depositing eggs halves with metabolites H1. Both males females were susceptible H1 significantly arrested larval development at least 40% lethal larvae. median time (LT50) challenged 3 2 d, respectively. Moreover, disrupted intestinal integrity pH value resulted increase load guts hemolymph. Mechanistically, infection led activation dual oxidase (DUOX)‐ROS‐Jun N‐terminal kinase (JNK) pathway. findings showed entomopathogen could potentially act as biological control agent against , advancing fundamental concepts integrated management programs

Abstract Dengue virus (DENV) and Zika (ZIKV) have emerged as major global public health challenges, causing numerous infections fatalities each year. However, current measures, including vaccines treatments, are often limited or ineffective. This highlights the urgent need for novel preventive strategies to control spread of key mosquito‐borne viruses like DENV ZIKV. In a recent study published in Science, Zhang et al. isolated bacterium named Rosenbergiella _YN46 from gut field‐caught Aedes albopictus mosquitoes Yunnan Province, China. commentary reviews their findings, on April 19, 2024, which describe symbiotic Rosenbergiella_YN46 its ability block flavivirus transmission, both The shows promising potential future dengue fever prevention provides valuable insights into biological approach controlling viral diseases.
