abstract
Different temperature has significant impact on the life cycle of Plutella xylostella (L.) and for effective management of diamondback moth (DBM) requires knowledge of effect of temperature on different stages of DBM. In current study survival rate from egg to adult emergence was found to vary from 80 to 69 %. Maximum survival was observed at 20±1 ℃ (80 %), 25±1 ℃ (77%) and 27±1 ℃ (74%) whereas, minimum survival was observed at 30±1 ℃ (69 %). The survivorship curves were observed to be type III curves. Indicate that the mortality at later stage of development like pupa or adult would have greater impact on population. In general, the force of mortality was high in first larval instar and pupal stage however, during third and fourth larval instar death rate curve was more or less steady during all temperatures. The overall mean death rate during 20±1℃ was found to be low as compared to other temperatures.
