Which anthranilic diamide is commonly recognized for its use in pest control?

1. Rynodine

2. Chlorantraniliprole

3. Fipronil

4. Abamectin

The correct answer is: Chlorantraniliprole

Chlorantraniliprole is a well-known anthranilic diamide that is extensively used in pest control due to its effectiveness against a variety of pests, particularly caterpillars and beetles. This compound works by interfering with the ryanodine receptor, which plays a crucial role in calcium regulation within muscle cells. When these receptors are activated in the target insects, it leads to uncontrolled release of calcium, ultimately resulting in paralysis and death. Its selectivity allows for safer use in integrated pest management (IPM) programs, reducing non-target effects on beneficial organisms. This makes chlorantraniliprole a sought-after option among pest management professionals for tackling pest populations while mitigating environmental impact. In contrast, the other options listed are not classified as anthranilic diamides. Rynodine refers to a class of compounds that includes chlorantraniliprole but is not itself used directly in pest control. Fipronil is a different type of insecticide that disrupts the insect's nervous system. Abamectin is an avermectin used primarily for its action against mites and some insects but does not belong to the anthranilic diamide group.
