ABSTRACT
The infestation of stored grain insects depends upon both biotic and abiotic factors, but abiotic factors are directly related to storage stability. The optimum temperature and moisture content required for growth and development of stored grain insects. The moisture content considerably affects pest status, but it is not a factor which can be cost-effectively manipulated, in most cases, to achieve sufficient control of insect pests. Insect development and population growth rates are directly affected by temperature, moisture, and relative humidity. If stored grain contains some inert materials or broken grain, it would provide favorable condition for insect infestation, particularly, development of hot spot. The broken grain acts as harbor of greater number of mould spore and storage fungi. This grain tends to saturate inter granular air with humidity and availability of moisture content increases for insects and storage fungi.
