Abstract

In Nilgiris, the larval population of diamond backmoth Plutella xylostella L. in cabbage was more from December to May with its peak activity during April. Diadegma semiclausm (Horstmann) and Cotesia plutellae (Kurdjumov) are widely established larval parasitoids. Activity of D.semiclasm was more during September. Level of parasitism by D.semiclausm was not influenced much by weather elements and host density. The parasitism by C. plutellae was more in hot-weather period and parasitoid activity was influenced by host density. Maximum temperature, and morning relative humidity had positive influence whereas, evening relative humidity had negative influence on C. plutellae p
