Abstract
Studies on natural parasitism on eggs ofP. perpusillabyParachyryso charis javensis were undertaken during two consecutive years i.e. 1992–93 and 1993–94 at G.S. Sugarcane Breeding Institute farm. High parasitism level (42.50% and 37.57%) during August 1992–93 and 1993–94 indicated that P.javensis. is the important mortality factor in the 2nd generation ofPyrilla. The parasitism level was found sharply decreased in the month of September due to oviposition in leaf-sheath and fall in temperature under agro-climatic condition of Eastern U.P., India.
