Effects of parasitoids on the juvenile hormone titre in Lymantria dispar.
Abstract
Insect metamorphosis and reproduction are controlled by several closely related compounds called the juvenile hormone (JH). Defects in JH production or treatments of insects with JH agonists cause lethal developmental derangements or sterility. It is assumed that certain effects or parasitoids on insect development are mediated by changes of JH titre in the host. These suggestions have not been verified because the measurements of JH titre have been tedious, expensive, and often not reliable. We propose to develop jointly a novel method of JH quantification and to test the impact of two parasitoids on the JH titre in the caterpillars of the gypsy moth, Lymantria dispar.
