What is the primary mode of action of a behavioral deterrent__________________?
Show answer Hide answer
Answer: C. Prevent feeding and oviposition of an insect
Explanation
Behavioral deterrents act primarily by preventing both feeding and oviposition behaviors in insect pests. These chemical compounds discourage insects from consuming treated plant tissues or laying eggs upon them. Disrupting these vital behavioral patterns protects crops without necessarily killing the insect directly. Behavioral deterrents include antifeedants and oviposition deterrents that alter normal insect response pathways. These compounds often stimulate sensory sensilla on the insect tarsi or mouthparts to signal unpalatability. Using deterrents is a key component of eco-friendly pest management designed to reduce crop damage safely.
Farmers apply behavioral deterrents to organic crops to protect yields while avoiding synthetic neurotoxic pesticides. Plant secondary metabolites often function naturally as behavioral deterrents against herbivorous insect attacks. This approach reduces selection pressure for pesticide resistance compared to lethal chemical knockdown agents. Preventing only feeding ignores the equally important role of stopping insect egg deposition on crops. Focusing exclusively on oviposition fails to account for the cessation of destructive feeding activity. Selecting none of the above is wrong because behavioral deterrents clearly inhibit both feeding and egg-laying.
