An insect growth regulator (IGR) is a chemical insecticide that kills insects indirectly by disrupting their life cycles. [1] . The term was initially proposed to describe the effects of juvenile hormone analogs. [2] . Although the term "insect growth disruptor" more accurately describes the actions of IGRs, it did not become widely used. [1] .
28 sty 2024 · Insect growth regulators (IGRs) are insecticides that mimic hormones in young insects. They disrupt how insects grow and reproduce. IGRs can control many types of insects including fleas, cockroaches, and mosquitos. Although they are rarely fatal for adult insects, they can prevent reproduction, egg-hatch, and molting from one stage to the next.
Insect growth regulators are compounds derived from, or inhibitory to, insect hormones and include methoprene, a juvenoid or juvenile hormone mimic, effective against mosquitoes, and diflubenzuron, which disrupts the synthesis of chitin and kills insects when they molt.
21 wrz 2023 · Insect growth regulators (IGRs) are products that affect insects’ ability to grow and mature normally, by disrupting life processes unique to insects. For example, for an insect to grow, it must molt, shedding its external skeleton (or shell) and produce a new, larger one.
10 cze 2021 · Insect growth regulators (IGRs) inhibit certain fundamental processes required for the survival of insects, thereby killing them. Furthermore, these compounds are highly selective and less toxic to nontarget organisms [ 23 ].
1 sty 1997 · The control of stored product insects with insect growth regulators (IGRs) was heralded in the 1970s as a potentially valuable alternative to the use of traditional insecticides. Initially, the IGRs included compounds that mimicked the insects' own juvenile hormone.
Insect growth regulators can be derived from plants or from a combination of synthetic and natural substances. Nowadays, research is being done on the chemical makeup of naturally occurring insect hormones, with the goal of creating analogs or mimics that will work against insects.
