摘要：

In our continuing search for new insect control agents from plant sources, eight nagilactones were isolated from Podocarpus nagi (Podocarpaceae). The effects of the four most abundant on the feeding and growth of larvae of the tobacco budworm, Heliothis virescens (Lepidoptera: Noctuidae) were investigated. The growth rate and the pupation of H. virescens fed on diets containing nagilactone D [4] were lowered and mortality was occasionally observed. The data strongly suggest that growth inhibition is caused by feeding deterrence of these norditerpene dilactones and that nagilactone D is the most potent in inhibiting the mouthpart sensory receptors.
