Insect symbiosis and bacterial influences

The green peach aphid, Myzus persicae (Sulzer), is a globally important agricultural pest whose management is increasingly challenged by widespread insecticide resistance, prompting interest in alternative and sustainable control strategies such as endophytic fungi. This study evaluated the effects of two endophytic f…

Bal arısı (Apis mellifera L.), ekonomik açıdan bitkisel tarım ürünlerinin dünyadaki en önemli tozlaştırıcısıdır. Bal arılarını olumsuz etkileyen etkenler, onların yaşama gücünü ve verimini düşürebilmektedir. Bu tehditlerden biri de Paenibacillus larvae’nın neden olduğu Amerikan Yavru Çürüklüğü (AYÇ) enfeksiyonudur. P.…

Abstract This study describes Vairimorpha rumexii sp. nov., a newly identified microsporidian parasite infecting Gastrophysa viridula , the green dock leaf beetle, in northeastern Türkiye. Microscopic examination revealed 2 distinct spore types, with light microscopy and Giemsa staining confirming both disporoblastic…

Microsporidia are obligate intracellular parasites that predominantly cause chronic infections in their hosts, relying entirely on host cells for development and reproduction. Among entomopathogenic microsporidia, climatic variables such as temperature and humidity are pivotal in influencing infection dynamics. This s…

Insect-associated microbiomes are complex, functionally integrated associations inhabiting insect guts, cuticles, reproductive organs, and specialised symbiotic tissues. Over evolutionary time, these partnerships have expanded host metabolic capacity and shaped nutrition, development, immune regulation, behaviour, and…

Endosymbiotic bacteria play fundamental roles in arthropod biology, by influencing development, reproduction, and ecological interactions. Among them, Wolbachia is the most widespread and impactful symbiont, capable of manipulating host reproduction through mechanisms such as cytoplasmic incompatibility (CI), partheno…

Beauveria bassiana is a well-recognized entomopathogenic fungus extensively employed insustainable pest management programs as an environmentally benign alternative to conventional chemical pesticides. Although its efficacy as a biopesticide is well established, early immune responses of insect hosts to B. bassiana in…

Ignatzschineria larvae are a recently characterized bacterium with limited ecophysiological data and are proposed as a potential microbial biomarker for insect colonization. We isolated I. larvae (strain MW602513) from the gut of an aquatic insect and assessed their tolerance and antibiotic susceptibility (Kirby-Bauer…

Insect-associated microbiomes, as co-evolved members of the holobiont, play pivotal roles in host physiology, ecological resilience, and evolutionary innovation. This review synthesizes recent advances in understanding microbial symbionts' contributions to metabolic adaptation, insecticide detoxification, and immune m…

Aphids are important agricultural pests that interact with diverse bacterial taxa living within or associated with their bodies. Some bacteria, such as the obligate symbiont Buchnera aphidicola, provide essential nutritional functions and are predominantly inherited vertically, whereas other aphid-associated bacteria…
