一、定义(Definition)影响昆虫的生长发育（抑制、促进）Insect Growth Regulators (IGRs), also called thirdgeneration insecticides, are pesticides that disrupt thenormal activity of the endocrine or hormone system ofinsects, affecting the development, reproduction, ormetamorphosis of the target insect.They have amuch slower mode of actionthan synthetic chemical insecticides
