comment:
The leaf-roller, Diaphania (Margaronia) pulverulentalis (Hampson) (Lepidoptera: Pyralidae), a pest of mulberry, was first recorded in Karnataka during 1995. Seasonal occurrence of the leaf-roller and its parasitoids, Phanerotoma noyesi Zettel, Apanteles agilis Ashmead and A. bisulcata Cameron (Hymenoptera: Braconidae) was studied for three years from September 1995 to August 1998, near Bangalore, India. The leaf-roller infestation on mulberry begins after commencement of South-West monsoon during June and infestation is severe during North-East monsoon and winter, from October to December, and then declines and tapers off by next April. P. noyesi is the most common and widespread parasitoid. A. agilis occurred during winter, in the third year of survey. A. bisulcata occurred sporadically during rainy seasons. none
