What term describes the application of a pesticide that targets juvenile insects?

The application of a pesticide that specifically targets juvenile insects is referred to as "larvicidal." This term derives from "larvae," which are the immature stages of insects. Larvicidal products are designed to disrupt the development of these young insects, effectively preventing them from growing into adults and reproducing. This approach can be particularly effective in controlling pest populations by targeting them at a vulnerable life stage when they are more susceptible to pesticide action.

In contrast, adulticidal products are designed to target mature insects, while ovicidal products focus on killing the eggs laid by insects. Systemic pesticides are absorbed by plants and can act throughout their tissues, targeting insect pests that feed on them, but they do not specifically target juvenile forms. Each type of pesticide has a distinct purpose in pest management, and understanding these differences is crucial for effective and responsible use in agriculture.
