Therefore, the immunity of an insect can be controlled artificially by inorganic ions.CONSTITUTION: Insecticide susceptibility of a noxious insect is induced quickly and exactly by using one ion of inorganic ions such as calcium, magnesium, sodium and potassium. Therefore, these inorganic ions are added to an insecticide during the production of insecticides.© KIPO 2002
