Which compound is noted for its use as a Gylcoside insecticide?

The compound noted for its use as a glycoside insecticide is abamectin. Abamectin functions by interfering with the nervous system of insects, primarily acting as an insect neurotoxin that binds to glutamate-gated chloride channels. This results in paralysis and death of the targeted pests.

Glycosides are compounds formed from a sugar and another substance, which, in the case of abamectin, contributes to its effectiveness as an insecticide. Abamectin is derived from the fermentation of a soil bacterium and is widely used in agricultural and commercial pest control due to its effectiveness against a broad range of insects and mites.

In contrast, diatomaceous earth works mechanically by dehydrating insects, boric acid is primarily used as an insect stomach poison and desiccant, and Ficam is a brand name for a different type of insecticide that contains bendiocarb, which is a carbamate insecticide. Each of these substances operates through different mechanisms that are not associated with glycoside action, making abamectin the correct answer for this question.
