Which insecticide group is known for its nervous system targeting properties?

The insecticide group known for its nervous system targeting properties is pyrethroids. Pyrethroids are synthetic chemicals modeled after the natural insecticides found in chrysanthemum flowers. They act on the nervous system of insects, disrupting normal nerve function. This mechanism typically involves the prolongation of sodium channel activation, leading to paralysis and ultimately the death of the insect.

In contrast, insect growth regulators (IGRs) focus on disrupting the development processes of insects rather than targeting their nervous systems. Herbicides are designed to control unwanted plants rather than insects, and fungicides specifically target fungal pathogens. This distinction highlights the specificity of pyrethroids in targeting insect physiology, making them particularly effective for managing pest populations.
