| Abstract |
Insecticides are often produced to target specific endocrine functions controlling processes like molting and metamorphosis of arthropod larvae. Of particular concern are the effects of juvenile hormone analogues such as methoprene, on non-target arthropods. The aim of this study was to examine the influence of methoprene on molting of the estuarine mysid Neomysis integer. Subadults and < 24h old juveniles were exposed for 3 weeks to 0.01, 1 and 100 µg methoprene/l. Methoprene delayed molting at concentrations 1 and 100 µg/l in the < 24h old juveniles, whereas no effects were observed on subadults. These results demonstrate that insecticides are capable of disrupting molting in non-target organisms. Furthermore it is concluded that molting is a useful endpoint to examine endocrine disruption in Neomysis integer |
