title: Reproductive costs of the immune response of the autogenous mosquito Culex pipiens molestus against inoculated Dirofilaria immitis.
abstract: Culex pipiens molestus is an autogenous mosquito, a vector of Dirofilaria immitis in Madeira Island, and it mounts a melanotic encapsulation response when inoculated intrathoracically with D. immitis microfilariae (mf). Because Cx. p. molestus is autogenous, this mosquito is a good model from which to gain a better understand the relationship between oviposition and melanization, independent of the signaling pathways related to blood feeding. The present work assessed the impact follicle growth might have on melanization of intrathoracically inoculated mf. The ovaries from mosquitoes undergoing melanotic encapsulation developed more eggs than those that could not melanize the mf. Possible explanations are discussed in this article.
