Effect of temperature and relative humidity on the population dynamics of some insect pests of maize.

Abstract

These studies were carried out Entomological Research Area, Department of Agricultural Entomology, University of Agriculture Faisalabad during 2004-2005 on four verities of Maize (Neelam, Akbar, Sultan and Sadaf). The results show that the population of leaf hoper was found highest at temperature of 36.5C and relative humidity at 68%. The lowest population was observed at the temperature of 31.5C and relative humidity at 75%. The population of jassid was found highest at the temperature of 36C with relative humidity at 68% and lowest population was found at 35C relative humidity at 70%. The infestation of Chilo partelous was found highest at the temperature of 32.5C relative humidity at 68% and lowest infestation of chilo partellous found at the temperature of 32.5C relative humidity at 50%. The overall results of current research work showed that the relative humidity and temperature significantly effect on the population of insect pests of maize.
