Abstract

Weather factors have always been found to be important for insect pests survival, growth, development, fecundity and reproduction. An investigation was undertaken to study the population of major insect pests of rice influenced under different weather parameters in rice field ecosystem of Eastern Uttar Pradesh, India for two consecutive years, 2014 and 2015. The population of major insect pests of rice were observed under particular weather parameters, i.e., temperature maximum, temperature minimum, relative humidity, and rainfall in different growth stages of rice. The influence of weather parameters on population of major insect pests of rice were inferenced by correlation coefficient. Of the total observed population of rice insect pests under damaging groups in all growth stages of rice under temperature maximum, temperature minimum, relative humidity, and rainfall, the correlation coefficients were - 0.669, - 0.649, - 0.564, and 0.821 for stem borers; 0.859, 0.846, 0.784, and - 0.
