SHEDDING LIGHT ON IGRs AND END BUGS

摘要

Insect growth regulators are one of the mosi oft-used insecticides for bed bugs. Here's what we found when we systematically put them to the test... Insect growth regulators (IGRs) have a long history of effective use against urban pests, including fleas, cockroaches, termites, stored product invaders and mosquitoes. IGRs are attractive management tools because of their prolonged effect and low mammalian toxicity. They also have novel modes of action, making them useful when combatting resistant pestpopulations. Different types of IGRs have different modes of action. The class of compounds used to control termites disrupts molting by interfering with formation of chitin, a foundation of insect cuticle. IGRs the industry uses to fight fleas, cockroaches, mosquitoes (and bed bugs) on the other hand mimic insect juvenile hormone (TH). Naturally occurring levels of this hormone in insects regulate growth, development and reproduction.
