Main Article Content
Abstract
Pectinophora gossypiella (pink bollworm) is major lepidopteron pest of many crops throughout the world, but it cause major infestation to cotton crop. Presently we have done the biology of pink bollworm on their natural diet cotton bolls, flowers, and squares and observed the effect of different temperatures (27, 31, and 35±1 °C) on their development rate. During present study the maximum development rate was observed on 27±1 °C while minimum development rate was observed on 35±1 °C. Total Cumulative percentage of survival was observed 69.5%. Highest mortality was observed in 1st larval instars and lowest mortality observed in 4th larval instars.
