Abstract

Natural parasitization in eggs of Lymantria obfuscata Walk. at Srinagar (J. & K.).

Abstract

The timing and level of parasitization of eggs of the lymantriid Lymantria obfuscata (a defoliator of trees in India, particularly poplars [Populus], willow [Salix], walnut [Juglans] and apple) by the eupelmid Anastatus is described. Parasitization during a 6-month period from August 1983 to January 1984 ranged from a minimum of 15.78 (in November) to a maximum of 20.89% (in August). A proportion of the parasitoids emerged after diapause was terminated in the host eggs. It is concluded that Anastatus can overwinter in host eggs and emerge after the host completes diapause.
