What are common types of insecticides used in pest control?

The selection of pyrethroids, neonicotinoids, organophosphates, and biological insecticides as common types of insecticides in pest control is correct because these categories represent widely used classes of compounds that target insect pests effectively.

Pyrethroids are synthetic chemicals modeled after pyrethrins, which are natural insecticides derived from chrysanthemum flowers. They work by disrupting the nervous system of insects, providing fast-acting control.

Neonicotinoids are another class of insecticides that act on the nervous system of insects but are specifically designed to mimic nicotine. They are notable for their systemic action, meaning they can be absorbed by plants and affect pests that feed on treated plants.

Organophosphates are a group of insecticides that function by inhibiting important enzymes in the insect's nervous system, leading to paralysis and death. They are effective against a broad range of pests.

Biological insecticides, on the other hand, include naturally occurring microorganisms or compounds derived from natural sources that control pests by various biological mechanisms, providing a more environmentally friendly pest management option.

The other answer choices do not adequately encompass the common types of insecticides used in pest control. Chlorinated hydrocarbons and carbamates, while also used in
