Spiromesifen is an insecticide/acaricide belonging to the spirocyclic tetronic/tetramic acid derivatives class. It acts on lipid synthesis by inhibiting acetyl CoA carboxylase and causes a significant decrease in total lipids. We investigated the potential effect on the fecundity/fertility of Ae. aegypti exposed to sublethal concentrations of spiromesifen using bottle bioassay. The rates of oviposition and hatching were significantly reduced, besides the content of lipids and carbohydrates of females exposed to sublethal concentrations of spiromesifen.
