Effect of different type of rice grains on angoumous grain moth, Sitotroga cerealella (olivier)

A study was carried out to know the effect of different type of rice grains on development and survival of Angoumois grain moth, Sitotroga cerealella (Olivier). The maximum adult emergence were recorded in dehusked grain, which was significantly superior over rest of the grain types and was followed by grain with husk, degermed grain soaked in water and degermed grain without soaking. The growth index was highest in dehusked unpolish grain and was followed by the grain with husk. The pest could not developed on polished rice grains. .
