Explanation

Grain moisture is the critical factor for pest growth in stored grains, as most storage insects require specific moisture levels for reproduction and development. While temperature also affects pest activity (higher temperatures increase metabolism), moisture is the primary limiting factor - even at optimal temperatures, pests cannot thrive in very dry grain. Adequate moisture enables fungal growth, which further facilitates pest infestation.
