MEDIUM FOR CULTIVATING MICROORGANISM, INSECT PEST CONTROLLING TOOL AND INSECT PEST CONTROL USING SAME MEDIUM

摘要

PURPOSE:To obtain a naturally degradable insect pest controlling tool having high insecticidal effects, capable of being readily arranged on trees from which insect pests have to be expelled by efficiently culturing microorganisms with which insect pests are infected or a spore thereof by using a microorganism culturing medium prepared by impregnating rice straw with a medium component. CONSTITUTION:A medium component is impregnated into rice straw sterilized preferably by hot water, especially rice straw rope to give a microorganism culturing medium capable of efficiently culturing microorganisms. A microorganism with which insect pests are infected and/or a spore thereof is cultured in the medium to give an insect pest expelling tool showing excellent insecticidal effects on insect pests such as long-horned beetles and May beetle. The insect pest controlling tool is readily arranged on trees from which insect pests have to be removed by winding the tool around trees or hanging from trees, has smaller harm to men and animals than a chemical insecticide and does not require recovery because of natural degradation.
