Abstract

A survey of the species composition and relative abundance of Diaphania caesalis Walker (Lepidoptera: Crambidae) in plantations of jackfruit (Artocarpus heterophyllus Lam.) in three southern states along India's western coast recorded thirteen species of primary parasitoids and one species of a hyperparasitoid, namely Tetrastichus pantnagerensis Khan (Hymenoptera: Eulophidae). Apanteles stantoni Ashmead (Hymenoptera: Braconidae) was the most dominant parasitoid and found in 35% of the parasitised host larvae in Karnataka, 38.5% in Kerala, and 33.1% in Tamil Nadu whereas the overall level of parasitisation, involving all the different parasitoids recorded, was approximately 41%-45% and did not vary significantly with location.
