Microwave Energy in Controlling Warehouse Insects (Sitophilus oryzae L) and Determining the Percentage of Killing on the Unit Weight of Wheat Seeds

Abstract

Sitophilus oryzae L (Coleoptera) is a primary pest of stored grains in many regions of the world. This research paper aims to use non-traditional methods to control some insects on stored grain. The use of insecticides and their side effects on health and the environment, in general, are proven Pest control should take another direction. Wheat samples were taken with different weights of 10, 20, 40, 60, 80, 100, 200 g for three separate packages, and (30) insects of Sitophilus oryzae L were added to each sample and were mixed randomly., 5, 10, 15, 20, 25 '30' seconds to calculate the time on the amount of weight of treated seeds to give the best results weight 10 g, microwave treatment, time of 20 seconds, the killing rate was 100%, and 15 seconds was 90%. Weight 20g Microwave treatment for 25 seconds (100 percent kill rate) and 20 seconds (92.30 percent kill rate) for optimal results. Weight 40g Microwave treatment for 20 seconds (100 percent kill rate) and 15 seconds (76.10 percent kill rate) for optimal results. Microwave 60g for 25 seconds for a 100% kill rate and 20 seconds for an 88 percent kill rate for optimal outcomes. Microwave 80g for 25 seconds for a 100% kill rate and 20 seconds for an 86.60 percent kill rate for optimal outcomes. For optimal results, microwave 100g for 30 seconds for a 100% kill rate and 25 seconds for a 99.80% kill rate. Microwave 200g for 35 seconds for a 100% kill rate and 30 seconds for a 99.60% kill rate for optimal outcomes. From this, we can deduce that the time needed to kill all insects in the sample preparation for testing must be doubled for every 20 g of wheat seeds added.
