Abstract

These studies were carried out in Krishi Vigyan Kendra research area under Rajmata Vijyaraje Scindia Krishi Vigyan Kendra , Zonal Agriculture Research Station, Morena , M.P. During the year 2011~2012 in Kharif season on four verities PEHM-2, Maharaja, NK-6240, NK-30. The result shown that the different insect pest population such as Leaf hopper, Stem borer, Jassid, Aphid etc. The results show that the population of leaf hoper was found standard meteorological week 34 highest at temperature of 31.5℃ and relative humidity at 75%. The lowest population was observed SMW 31 at the temperature of 30.4℃ and relative humidity at 83%. The population of jassid was found standard meteorological week 34 highest at the temperature of 31.2℃ with relative humidity at 75% and lowest population was found standard meteorological week 32 at 28.6℃ relative humidity at 73%. The infestation of Stem borer (Chilo partelous) was found standard meteorological week 38 highest at the temperature of 29.5℃ relative humidity at 85% and lowest infestation standard meteorological week 34 of Chilo partellous found at the temperature of 31.2℃ relative humidity at 75%. The over all results of research work presented that the temperature, relative humidity are very responsible factor of the infestation of insect pest population in maize crops in Kharif season in Morena district.
