It is also poisonous to amphibians, such as frogs, salamanders and toads. Methoprene mimics a juvenile growth hormone, preventing mosquito larvae from maturing into adults. In 1996, after further studies, the EPA concluded that the actual use of methoprene as a mosquito control didn’t spread enough of it to harm other species, and recommended that the restriction “do not use in fish-bearing waters” be removed from the label, and instead, the warning should read, “this product is toxic to aquatic dipteran (mosquitoes) and chironomid (midge) larvae”–though of course its toxicity to mosquito larvae is the whole point. Don’t be disappointed if the larvae are still happily wriggling the next day! An IGR disrupts and impedes the life cycle of insects in the egg and larvae stage of development. Efficacy of methoprene for mosquito control in storm water catch basins. In contrast, the primary follicles of methoprene-treated mosquitoes were still round in shape and the size of these follicles was similar to that of the follicles of the ovaries dissected from control mosquitoes at 24 h PBM (Fig. Driven to satisfy our customers, we are constantly producing new innovations.
