BACKGROUND: The parasitic wasps Eretmocerus mundus, Eretmocerus eremicus and Encarsia formosa are important natural enemies of whiteflies. A broad understanding of their biology, ecology and behavior has been achieved, but the composition and role of theirmicrobiota is not fully determined. The knowledge of the bacteria present in insectsmight be useful tomanage species of human concern such as natural enemies or pests. Here, we performed a residual contact test to study a possible change in the susceptibility of E.mundus adults to abamectin insecticide after antibiotic treatment. Moreover, we assessed the microbiota present in adults of E. eremicus, E. formosa and two strains of E. mundus by MiSeq 16S rRNA amplicon sequencing. Finally, enzymatic tests were done to determine the influence of Arthrobacter species in the susceptibility of E. mundus to pesticides. RESULTS: The assays showed that when E. mundus adults were pretreated with antibiotic, the toxicity of abamectin was significantly higher. Among the different bacteria associated with parasitic wasps, Arthrobacter has been shown to be involved in the degradation of several kinds of pesticides. Four Arthrobacter species were detected in all the studied insects and the presence of esterases in this bacterial species was confirmed. CONCLUSIONS: The results suggest that the microbiota can modify the susceptibility of E. mundus to pesticides, which in turn supports the importance of the microbial community in natural enemies that it should be considered as a factor in risk assessment tests of pesticides.
