摘要：An investigation is carried out to assess the feeding biology, dietary utilization and reproduction of Lepidoptera in general, interaction of host plant biochemical and nutrients with the defensive mechanism of the Lepidoptera and host plant selection of Monarch butterfly, Danaus chryssipus. Danaid butterflies usually feeds on the plant juice from Calotropis gigantea. The attraction of danaid butterflies on the Calotropis gigantea is mainly due to the presence of PA s on the host plants. PA s of Danaid host plants is involved in male reproduction as well as pheromone production of insects. Danaus chrysippus reared on young leaves and inflorescence had shorter larval duration, improved longevity and higher fecundity. This may be due to the higher water content and glycoside concentration.
