Abstract:

Wolbachia is a common and widespread group of bacteria found in arthropods. These bacteria have evolved various mechanisms for manipulating reproduction of their hosts. The presence of Wolbachia in a laboratory population of Corcyra cephalonica (Stainton) was firstly identified based on amplification and sequencing part of the wsp gene. Aligned the obtained sequence with the published ones, the phylogenetic relationships among Wolbachia found in C. cephalonica and other insects were established. The Wolbachia found in C. cephalonica belong to the Pip group, far separated from the groups of Wolbachia found in braconid wasps and Trichogramma spp. It was so inferred that Wolbachia did not transmit horizontally between C. cephalonica and its parasitoids (Apanteles sp. and Trichogramma spp.).
