What does susceptibility refer to in the context of pesticides?

In the context of pesticides, susceptibility specifically refers to the sensitivity of a pest to a pesticide treatment. This means how adversely a pest reacts when exposed to a particular pesticide. For effective pest management, understanding susceptibility is crucial, as it influences the choice of pesticide to be used, the dosage applied, and the timing of application. Different pests have varying levels of susceptibility to different active ingredients, which can be affected by factors such as their life cycle, behavior, and any prior exposure to specific pesticides. Recognizing this sensitivity helps in managing resistance and ensuring that pest control efforts are both efficient and environmentally responsible.
