Biological Control of Pests — Predicted 2026

AI-Predicted Question Angles for UPSC 2026

Based on trend analysis, current affairs, and recurring themes in Biological Control of Pests.

Application-based scenario questions

high

Instead of direct recall, questions might present a scenario (e.g., 'A farmer observes X pest on Y crop and wants an organic solution...') and ask to identify the most suitable biocontrol agent. This tests application of knowledge rather than just memorization. For example, a question might describe symptoms of root rot and ask which fungus would be beneficial, leading to *Trichoderma*.

Detailed mechanism of action for Bt toxin

medium

While the general mechanism of Bt is often asked, a slightly more detailed question focusing on the specific steps (solubilization in alkaline gut, activation by proteases, binding to specific receptors, pore formation) could appear. This requires a deeper understanding beyond just 'it kills caterpillars'.

Distinguishing between different types of natural enemies

medium

Questions might specifically ask to differentiate between predators, parasitoids, and pathogens, providing examples and asking for their correct classification or mechanism. For instance, 'Which of the following is a parasitoid?' with options including a ladybug, Bt, and *Trichogramma* wasp. This tests conceptual clarity on the roles of different biocontrol agents.

Impact of non-target effects and risk assessment

low

While NCERT emphasizes the benefits, a slightly advanced question might touch upon the potential (though rare) negative impacts of poorly chosen biocontrol agents, such as non-target effects or invasiveness. This would test a more critical understanding of the topic, though it's less common for NEET's direct recall focus.
