Entomology Quiz | Agriculture MCQ Practice for IBPS AFO 2026

1

What is the role of sanitation in IPM?

To ignore crop residues

To promote weed growth

To remove pest breeding sites and overwintering habitats

To provide shelter for pests

To attract more pests

Solution & Explanation Sanitation involves removing crop residues, weeds, and other debris that can serve as breeding sites or overwintering habitats for pests. This reduces pest populations and minimizes the need for chemical control, a key aspect of IPM promoted by ICAR.

2

What is the recommended humidity level during the late age (4th and 5th instar) silkworm rearing?

Solution & Explanation Maintaining a humidity level of 70-75% is recommended during the late age (4th and 5th instar) silkworm rearing. Adequate humidity prevents dehydration, promotes healthy growth, and reduces the risk of diseases. Higher humidity levels are maintained during early instars.

3

Which of the following is a potential benefit of using cover crops in IPM?

Suppression of weeds and provision of habitat for beneficial insects

Reduced soil fertility

Increased pest populations

Reduced water infiltration

Increased soil erosion

Solution & Explanation Cover crops can suppress weeds by competing for resources, improve soil health, and provide habitat and food sources for beneficial insects, such as predators and parasitoids. This enhances biological control of pests and reduces the need for chemical interventions, aligning with IPM principles advocated by ICAR.

4

Which insect pest is a major vector of Groundnut bud necrosis virus (GBNV)?

Aphids (Aphis craccivora)

Whitefly (Bemisia tabaci)

Thrips (Frankliniella schultzei)

Mites (Tetranychus urticae)

Leafhoppers (Empoasca kerri)

Solution & Explanation Thrips, specifically Frankliniella schultzei, are the primary vectors of Groundnut bud necrosis virus (GBNV). These tiny insects transmit the virus while feeding on groundnut plants, leading to significant yield losses.

5

Which of the following is a key principle of IPM regarding pesticide use?

Ignoring the impact on beneficial insects

Using pesticides only when necessary and based on economic thresholds

Applying pesticides preventatively on a calendar basis

Using the highest dose of pesticide possible

Relying solely on pesticides for pest control

Solution & Explanation IPM emphasizes using pesticides judiciously, only when pest populations reach economic thresholds and other control methods are insufficient. This minimizes pesticide use, reduces environmental impact, and prevents resistance development, aligning with ICAR's sustainable agriculture goals.
