Abstract

Because juvenile hormone (JH) controls insect development and its analogs are used as insecticides, juvenile hormone disruptors (JHDs) represent potential sources from which novel pesticides can be developed. Many plant species harbor JHD activity, which has previously been attributed plant secondary metabolites (i.e., diterpenes) that disrupt insect development by interfering with the JH-mediated heterodimer formation of insect juvenile receptor complexes. The results of the present study indicate that plant JHD activity is also concentrated in certain plant groups and families and that plant metabolites have insect group-specific activity. These findings suggest that reciprocal diversification has occurred between plants and insects through the evolution of the plant metabolites and JH receptors, respectively, and that plant metabolites could be developed into insect group-specific pesticides with limited effects on non-target species.
