Abstract
We studied the occurrence of Wolbachia in the parasitoid Gonatopus bonaerensis Virla (Hymenoptera: Dryinidae). In order to verify the existence of natural infections in the parasitoid, a field survey was conducted. Identification of Wolbachia was performed on the basis of 16S rDNA, wsp_F1, and wsp_R1-sequences. After the detection of the bacteria, infected specimens of G. bonaerensis were treated with a solution of tetracycline. In Tucumán, parasitoids hold Wolbachia endosymbiont, which seems to control the wasp's reproduction in the nature turning it into thelytokous. The symbiont was identified as the Wolbachia sp. wRi strain. The cure of infected unfertilized females determined the normal arrhenotokous parthenogenesis and the production of male offspring. As a consequence of this procedure, the male of G. bonaerensis is described for the first time.
