Egg collapse: Aedes aegypti (L.) eggs following exposure of the parent female mosquito to sublethal concentrations of transfluthrin. a Seed germination paper removed from an LC10 treatment oviposition bioassay cup, following a 24 h damp dry, and a full drying period. Solid line encircles embryonated, viable eggs. Dashed line encircles non-viable eggs with a collapsed chorion. b Cluster of collapsed eggs from an LC20 treatment oviposition bioassay, following a 24 h damp dry period, but not fully dried. c A cluster of eggs upon immediate removal from an LC30 treatment oviposition bioassay. d The same cluster of eggs, collapsed, following a 24 h damp dry and full drying period
