Egg melanization: dissected female Aedes albopictus (Skuse) reproductive tracts after exposure to sublethal concentrations of transfluthrin and upon conclusion of oviposition bioassays seven days post-exposure. a Control mosquito showing cleared oviducts and no late-stage development oocytes. b A reproductive tract following LC10 treatment with 10 or fewer retained eggs. c A reproductive tract following LC20 treatment with 20 or fewer retained eggs. d A reproductive tract following LC30 treatment with extreme egg retention. e A reproductive tract following LC30 treatment showing partial melanisation of retained eggs. f A reproductive tract following LC30 treatment showing full melanisation and tissue decay.
