Design of Postharvest Control System for Pest in Grain Storage with High Frequency

This peper present about design of system for pest control in grain storage with high frequency. This experiment study effect of pest on high frequency radiation and experiment for using high frequency to pests controlled in storage grains. Experiment were conducted on two room to compare the changes in rice weight caused by the effects of pests between the two rooms, first room was pest controlled with high frequency, second room was not pest controlled to make the environment like a normal warehouse, in these experiments Using Sitotroga cerealella as grain moth, the weight of grains at any distances from the antenna are investigated. The results show weight of grains between two room are different, Room with pest controlled by high frequency had a lower rate of grains weight reduction than other rooms, in last month for experiment the weight of grains from room was pest controlled with high frequency is 990 g, while weight of grains from the room was not pest controlled is 874 g.
