Overview of Distribution and Diversity of Wolbachia Endosymbiont among the Different Geographical Populations of Indian Uzifly, Exorista Sorbillans (Diptera: Tachinidae).

摘要

Microorganisms are unique life forms having great impact on functioning and perpetuation of biosphere.udAmong them, Wolbachia is ubiquitous gram negative rickettsial endosymbiont taking its shelter in somaticudand reproductive tissues of class insecta. Wolbachia induces variety of phenotypes within insects fromudreproductive parasitism to mutualism. Due to the infection dynamics of Wolbachia and its ability to induceudreproductive anomalies in their hosts, it has been touted as the most effective bio-control agent forudmanagement of insect pests and vectors. However, for implementation of any Wolbachia based bio-controludstrategies it is essential to know its distribution, diversity and interactions with their hosts. Wolbachiaudinteractions in Uzi fly Exorista sorbillans are well documented and are proposed as agents forudmanagement of this pest. However, their distribution and diversity across the entire Indian sub-continent isudleft void. In the current study 31 populations of Uzi fly collected from the Mulberry Silkworm belts ofudIndia have been screened and characterized. 213 samples were screened and infection dynamics in theudindividuals have been documented. The findings suggest high prevalence of AB Wolbachia superudinfections in field populations of Uzi fly. This important update on the infection status and diversity ofudWolbachia is of greater significance for implementation of the previously proposed Wolbachia based biocontroludstrategies of Uzi fly in India.
