Biology of poplar leaf folder, Botyodes diniasalis Walk. (Lepidoptera: Crambidae) on populus deltoides bartr. ex marsh

Botyodes diniasalis was first time reared on P. deltoides and biology of this species was studied in detail. Damaging symptom and nature of damage was also studied during July to August.
