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.

Introduction
Maize occupies an important place in Indian
Agriculture. It is the third most important cereal in
India after wheat and rice. The major maize growing
states are Uttar Pradesh, Bihar, Rajasthan, Madhya
Pradesh, Punjab, Andhra Pradesh, Himachal Pradesh,
West Bengal, Karnataka and Jammu & Kashmir,
jointly accounting for over 95% of the national maize
production. The estimate of maize production in 2007
was 13-14 million tonnes from an area of 7.2 million
hectares with an average productivity of 2 tons/hectare
As mentioned earlier, maize is traditionally grown
during the summer (monsoon) season, which is
accompanied by high temperatures (<35 degrees) and
rains. Rabi (winter) cultivation of maize is are latively
new introduction started in mid sixties in some
pockets of Bihar and South India, but now in the
country as a whole. Rabi maize has comparative
advantage of low incidence of diseases and insect
pests, crops do not suffer on account of heavy rainfall,
slow growth of weeds, etc. The one reason of low
production is the attacks of various insect pests. The
damage due to insect pest complex depends upon the
population trends in the field which, in turn, rely upon
their dynamically of the physical factors of their
immediate environment (Isard, 2004). A thorough
understanding of the exact relationship between the
change in environmental factors and those in the pest
population may not only help anticipate the pest losses
to the crop, but also help avoid them through some
well timed pest control measure (Aasman, 2001).
