Abstract

In the field the extent of parasitism of Plutella xylostelia larvae by Cotesia plutallae ranged from 5.50 to 36.80 per cent during 200t and 10.00 to 36.00 per cent during 2002 in Manipur. The Parasitoid was active from first week of February to second week of April. The maximum Parasitisation of 36.80 % on 3rd week of Murch, 2001 and 36.00% on 4th week of March, 2002 synchronized with the maximum incidence of host larvae. The activity of purasitoid was found to have a significant positivc correlation with incidence of host larval population, temperature mid sunshine, negative correlation with relative humidity and total rainfall in both the cropping seasons.
