Abstract

This study was carried out during rabi 2018 and 2019 to assess the impact of elevated CO2 and temperature on biology and predation efficiency of a coccinellid Menochilus sexmaculatus (F.) on cowpea aphid Aphis craccivora Koch. The pooled data revealed that the total larval period, total developmental period, adult longevity and total lifecycle of M. sexmaculatus decreased and the feeding efficiency of both grubs and adults increased with the elevated CO2 and temperature conditions.
