abstract
A study was conducted to know the extent of field carryover to storage godowns for grain insect pests of rice, blackgram, greengram and groundnut in Guntur district during 2015-16 and 2016-17, that is responsible for initiation of insect pest infestations and serious damage to grains. Among the stored grain insect pests only Angoumois grain moth, Sitotroga cerealella was recovered from the field collected paddy grain samples. During 2015-16, 46% of the field collected paddy grain samples were infested with S. cerealella, whereas during 2016-17, only 15% of the samples were found with infestation. There was no field infestation of bruchids in pulses and groundnut. Field infestations were influenced by grain moisture, delayed harvesting, proximity to mills and stores, and weather conditions.
