Review the solved problems below to understand question phrasing, answer choices, and step-by-step solution logic prior to starting the full interactive practice drill:

Sample Question 1
Entomology & Integrated Pest Management (IPM) MEDIUM • MULTIPLE_CHOICE
Pink bollworm (Pectinophora gossypiella) causes damage in cotton by:
A Root pruning
B Adults defoliating leaves
C Nymphs sucking phloem sap
D Larvae boring into squares and developing bolls, feeding on lint and seed
✓ Correct Answer: D - Larvae boring into squares and developing bolls, feeding on lint and seed
📖 Step-by-Step Solution & Conceptual Rationale:
Larval feeding inside cotton bolls leads to stained lint, hollow seeds, and rosetted blooms.
Sample Question 2
Entomology & Integrated Pest Management (IPM) EASY • MULTIPLE_CHOICE
Insects belonging to order Hemiptera (Aphids, Whiteflies) possess which type of mouthparts?
A Sponging
B Siphoning
C Piercing and sucking
D Chewing and biting
✓ Correct Answer: C - Piercing and sucking
📖 Step-by-Step Solution & Conceptual Rationale:
Hemipteran stylets pierce plant vascular bundles to feed on nutrient-rich phloem sap.
Sample Question 3
Entomology & Integrated Pest Management (IPM) MEDIUM • MULTIPLE_CHOICE
The insecticidal protein in transgenic Bt cotton (Cry1Ac / Cry2Ab) is derived from:
A Agrobacterium tumefaciens
B Bacillus thuringiensis
C Bacillus subtilis
D Escherichia coli
✓ Correct Answer: B - Bacillus thuringiensis
📖 Step-by-Step Solution & Conceptual Rationale:
Cry delta-endotoxin crystals bind to midgut receptors in susceptible lepidopteran larvae, lysing cells.
Sample Question 4
Entomology & Integrated Pest Management (IPM) MEDIUM • MULTIPLE_CHOICE
Economic Threshold Level (ETL) in IPM is defined as:
A The density where total crop failure occurs
B The pest population density at which management action should be taken to prevent reaching EIL
C The cost of insecticide
D Zero pest population
✓ Correct Answer: B - The pest population density at which management action should be taken to prevent reaching EIL
📖 Step-by-Step Solution & Conceptual Rationale:
ETL serves as an action trigger before pest numbers cause economic injury (EIL).
Sample Question 5
Entomology & Integrated Pest Management (IPM) EASY • MULTIPLE_CHOICE
Chrysoperla carnea (Green lacewing) is used in biological pest control as a:
A Parasitoid wasp
B Weed competitor
C Voracious predator of aphids, whitefly nymphs, and eggs
D Pathogenic fungus
✓ Correct Answer: C - Voracious predator of aphids, whitefly nymphs, and eggs
📖 Step-by-Step Solution & Conceptual Rationale:
Green lacewing larvae are aggressive generalist predators of soft-bodied agricultural pests.
Sample Question 6
Entomology & Integrated Pest Management (IPM) HARD • MULTIPLE_CHOICE
Which insecticide class acts as an acetylcholinesterase inhibitor in the insect nervous system?
A Organophosphates and Carbamates
B Diamides
C Neonicotinoids
D Pyrethroids
✓ Correct Answer: A - Organophosphates and Carbamates
📖 Step-by-Step Solution & Conceptual Rationale:
Inhibiting AChE causes continuous synaptic acetylcholine accumulation, causing paralysis and death.
Sample Question 7
Entomology & Integrated Pest Management (IPM) MEDIUM • MULTIPLE_CHOICE
Pheromone traps utilize synthetic female sex pheromones primarily for:
A Repelling birds
B Killing all pests directly
C Monitoring pest population dynamics and mating disruption
D Fertilizing plants
✓ Correct Answer: C - Monitoring pest population dynamics and mating disruption
📖 Step-by-Step Solution & Conceptual Rationale:
Pheromones attract male moths to sticky traps to establish population thresholds and disrupt mating.
Sample Question 8
Entomology & Integrated Pest Management (IPM) EASY • MULTIPLE_CHOICE
Locust swarms (Schistocerca gregaria) belong to which insect order?
A Coleoptera
B Diptera
C Hymenoptera
D Orthoptera
✓ Correct Answer: D - Orthoptera
📖 Step-by-Step Solution & Conceptual Rationale:
Desert locusts are Acrididae grasshoppers displaying solitaria and gregaria phase polymorphism.
Sample Question 9
Entomology & Integrated Pest Management (IPM) HARD • MULTIPLE_CHOICE
Honeybees (Apis mellifera) communicate food source direction and distance via the:
A Stridor noise
B Antenna tapping
C Pheromone flight only
D Waggle dance (figure-eight dance)
✓ Correct Answer: D - Waggle dance (figure-eight dance)
📖 Step-by-Step Solution & Conceptual Rationale:
Karl von Frisch decoded the waggle dance, showing how angle relative to gravity encodes solar azimuth.
Sample Question 10
Entomology & Integrated Pest Management (IPM) MEDIUM • MULTIPLE_CHOICE
Which pest is the primary vector of Citrus Tristeza Virus (CTV)?
A Citrus leafminer
B Fruit fly
C Whitefly
D Citrus aphid (Toxoptera citricida / Aphis gossypii)
✓ Correct Answer: D - Citrus aphid (Toxoptera citricida / Aphis gossypii)
📖 Step-by-Step Solution & Conceptual Rationale:
Aphids transmit CTV non-persistently during phloem probing.
