What is it about?
Wolbachia is an endosymbiotic bacterium widespread in insects. Here we discover that many female mosquitos carrying an introduced Wolbachia and developing from long-stored eggs or starved larvae lack functional ovaries and are infertile. These infertile females also take blood meals more often from humans.

Why is it important?
Wolbachia is a stable biocontrol agent artificially introduced into the mosquito Aedes aegypti to reduce the transmission of mosquito-borne diseases such as dengue. The novel impacts of Wolbachia discovered in this study inform the success of invasion of Wolbachia under some ecological circumstances where the mosquito eggs must persist in the absence of water for a period and where larval food is limiting, with additional implications for understanding barriers to the transmission of Wolbachia and other endosymbionts to novel hosts.
