Habrobracon hebetor is a globally acknowledged larval ectoparasitoid that widely used to control lepidopteran pests. Wolbachia natural endosymbiont regulates various aspects of the insect host biology. The ability H. paralyze and develop on larvae from five families was tested under laboratory conditions. Two lines wasp were used, “W+” containing naturally occurring supergroup B, “W−”, with eradicated by antibiotic treatment, followed propagation 20 subsequent generations. proportions in which paralysis, as well parasitoid oviposition, larval, pupal, adult development observed, usually higher W+ compared W−. In Loxostege sticticalis, differences these indices not statistically significant. Galleria mellonella, Mamestra brassicae, Ostrinia nubilalis, some parasitism significantly than Bombyx mori Plutella xylostella, could complete its life cycle, but levels at initial steps (from paralysis symptoms presence larvae/pupae parasitoid) 2–5 times lower W− (p < 0.01). It can be suggested advantageous for hebetor, it increases success broad range hosts.
