Impacts of abiotic factors and pesticide on the development, phenology, and reproductive biology of pink bollworm, <i>Pectinophora gossypiella</i> (Saunders) (Lepidoptera: Gelechiidae).

ABSTRACT: The pink bollworm, Pectinophora gossypiella (Saunders) (Lepidoptera: Gelechiidae) is a serious insect pest of cotton crop. The studies to evaluate the impact of abiotic factors on cotton pests' biology are limited. The current study was undertaken to determine the impact of abiotic factors (temperature, humidity, photoperiod) and an insecticide (lambda-cyhalothrin) on the biological aspects of P. gossypiella. The results revealed that all the treatments showed a significant impact on different life parameters of P. gossypiella. The temperature exposure at 27 °C revealed a total life span of about 33 days. Maximum mortality for larvae (51.11%), pupae (59.04%) and adults (61.92%) were recorded at 33 °C exposure. Both low and high humidity levels caused negative impacts o
