Among the several insects infesting apple, Eriosoma lanigerum Hausmann is a major pest of apple in Bharsar, Pauri Garhwal, Uttarakhand. A survey of its natural enemies was conducted and studies on their population dynamics made during 2008 and 2009. Fourteen natural enemies were recorded belonging to Coccinellidae, Syrphidae, Chrysopidae, Forficulidae and Anthocoridae. Coccinella septempunctata played an important role in the spring season, while in summer common earwig, Forficula auricularia, green lacewing, Chrysoperla carnea and syrphid flies (Syrphidae) were important. C. carnea and syrphid flies were observed from August to October.
