HORTICULTURE

Detailed explanation-1: -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.

Detailed explanation-2: -Tebufenozide, methoxyfenozide, halofenozide, and chromafenozide are examples of this type of IGR. Other IGRs inhibit chitin synthesis (necessary for exoskeleton formation).

Detailed explanation-3: -Mechanism of action IGRs prevent an insect from reaching maturity by interfering with the molting process. This in turn curbs infestations because immature insects cannot reproduce. Because these IGRs work by interfering with an insect’s molting process, they kill insects more slowly than traditional insecticides.

Detailed explanation-4: -The Sterile Insect Technique Mating of released sterile males with native females leads to a decrease in the females’ reproductive potential and ultimately, if males are released in sufficient numbers over a sufficient period of time, to the local elimination or suppression of the pest population.
