Abstract

Heterorhabditis indicus n. sp. is described from populations recovered from the sugarcane top borer, Scirpophaga excerptalis (Pyralidae : Lepidoptera) in the vicinity of Coimbatore, India. The new species can be separated from previously described heterorhabditids by its shorter infective stage juveniles, differences in ratio E (distance from anterior end to excretory pore divided by distance from anterior end to base of pharynx) and ratio F (body diameter of infective stage divided by length of tail) and the reduction of number and structure of the bursal papillae, especially the last two (numbers 8 and 9). Pot experiments showed that H. indicus n. sp. could infect larvae of the white grubs Holotrichia serrata and Leucopholis lepidophora (Scarabaeidae : Coleoptera). By growing H. indicus n. sp. in small drops of Galleria hemolymph, it was possible to produce a continuous series of hermaphrodites, without the intervention of a sexual cycle.
