Abstract

Incidence of parasites of Lymantria obfuscata (Lymantriidae: Lepidoptera) in Kashmir.

Abstract

The incidence of parasites of Lymantria obfuscata was studied in sites composed of favoured hosts of the pest, including apple, willow [Salix] and poplar [Populus], in Kashmir, India, during 1983 and 1984. The only egg parasite reared was the eupelmid Anastatus kashmirensis, parasitizing between 4.49 and 11.92% of eggs. From 15 study sites, as many as 10 475 larvae in different instars and pupae were collected and reared in the laboratory. The tachinids Exorista rossica and Compsilura sp. parasitized up to 8.42% and 0.89%, respectively, of the larvae of L. obfuscata. Of the 6 pupal parasites, the eulophid Tetrastichus sp. was dominant, accounting for 33.41% of the measured parasitism, followed by the ichneumonids Pimpla sp. and Theronia atalantae atalantae, which parasitized 6.84 and 4.03% of the pupae, respectively. The chalcidid Brachymeria intermedia parasitized up to 2.98%, whereas B. lasus, recorded for the first time in Kashmir, parasitized up to 2.01%, but was not widely distributed in the State.
