摘要： Parasitoid wasps are important biocontrol agents for agricultural pests, with increasing demand for their use in sustainable pest management practices. Endosymbiotic bacteria of parasitoid wasps can have a range of fitness effects on their insect hosts, and these could be manipulated to enhance commercial stocks. Here, we characterized the diversity and distribution of key endosymbiont species in parasitoids that are important to Australian agriculture. In total, we screened 12 species of field-collected aphid parasitoids, 32 species of field-collected lepidopteran parasitoids, and 11 commercially available parasitoid species sourced from biological control companies. Our results suggest that endosymbiont infections are uncommon across the different parasitoid species in Australia but are found in high frequencies within some species. Wolbachia was the most prevalent endosymbiont in field-collected aphid and lepidopteran parasitoids, and in commercially reared whitefly and scale insect parasitoids. These Wolbachia infections all belong to the Supergroups A and B. Our findings provide a useful basis for future investigations on the phenotypic effects of different endosymbiont infections, with a long-term view to support their effectiveness as agents for sustainable pest management.
