[Effects of juvenile hormone on vitellogenesis in Spilostethus pandurus (Hemiptera: Heteroptera)].
The effects of juvenile hormone (JH) on the control of vitellogenin appearance in the haemolymph of Spilostethus pandurus newly emerged females have been studied as well as their intake by developing oocytes. SDS-PAGE electrophoresis has been used as an analytical method for protein studies. JH induced early detection of vitellogenins in the haemolymph of treated insects and their accelerated incorporation by undeveloped ovaries. The results suggest that JH plays an essential role as a gonadotrophic agent, just as it has been described for other insect species.
