Survey ofLymantria obfuscata and its natural enemies in India

The status ofLymantria obfuscata Walker in India is discussed. Notes on its taxonomy, distribution, life-history and economic importance are given for comparison with those of the gypsy moth,Lymantria dispar (L.). Parasites ofL. obfuscata in India are reviewed. A survey in 1961–66 revealed an additional 50 species of natural enemies ofL. obfuscata in India. The incidence and biology of some of the important ones are presented. A comparison is made between these parasites and those ofL. dispar. Some of the natural enemies ofL. obfuscata already attackL. dispar in America. Others are closely related to the parasites of the gypsy moth. The scope for utilisation of parasites ofL. obfuscata in other countries is discussed. Possible use of parasites ofL. dispar from the U.S.A. or elsewhere againstL. obfuscata in India is suggested. Research financed in part by the U.S.D.A. under grant PL-480.
