The maternally inherited bacterial endosymbiont of arthropods Wolbachia is deeply integrated into the biology of its host and can be regarded as a component of the host cell. There is evidence that Wolbachia contributes to the fitness of the host species, including the increase in heat stress resistance and resistance to viral infections. However, the exact mechanisms of this contribution, as well as Wolbachia-host interactions in total, remain largely unclear. In order to study these mechanisms we composed several Drosophila melanogaster lineages with the same nuclear background (wild type Bi90 line) and different Wolbachia genotypes in cytoplasm. Here we showed that the symbiont did not effect on host insect heat stress resistance and fertility with the exception of two unique Wolbachia strains: the well-known pathogenic wMelPop strain and first discovered here wMelPlus.
