• Biology and Field Infestation of Potato Tuber Moth (Phthorimoea operculella):
• Adult Oviposition and Larval Entry: Female moths cannot burrow into firm, uncracked soil. In the field, moths preferentially lay eggs in soil cracks on potato tubers that are exposed to or close to the soil surface.
• Management via Earthing-Up: Deep planting and regular earthing-up to cover all tubers with at least 5 cm of uncracked soil effectively prevents tuber moth infestation, demonstrating that they cannot infest well-covered hidden tubers.
• Conclusion: Statement (I) is incorrect but Statement (II) is correct (Option 4).

• Insect Cuticle and Animal Names:
• Pair-by-Pair Matching:
• Arthropodin $\rightarrow$ (II) Zone beneath the wax layer: Arthropodin is the water-soluble structural protein of the untanned procuticle, situated directly beneath the epicuticle.
• Cement layer $\rightarrow$ (I) Tectocuticle: The outermost lipid-protective layer of the epicuticle (secreted by dermal glands) is termed the cement layer or tectocuticle.
• Pavo cristatus $\rightarrow$ (IV) Peacock: Scientific name of the Indian national bird (Indian Peafowl).
• Sus scrofa $\rightarrow$ (III) Wild boar: Scientific name of the wild swine/boar, an agricultural mammalian pest.
• Correct Choice: Option 3 maps (A)-(II), (B)-(I), (C)-(IV), (D)-(III).

Correct option: (3) (A) - (II), (B) - (1), (C) - (V), (D) - (ttl)

• Feeding Habits of the Cigarette Beetle (Lasioderma serricorne):
• Pest Biology: The cigarette beetle (family Ptinidae/Anobiidae) is an omnivorous pest of stored commodities.
• Hosts: It feeds vigorously on cured tobacco and dried pyrethrum flowers (resistant to nicotine and pyrethrins due to symbiotic yeast Symbiotaphrina), as well as high-protein animal meals such as meat meal and dried fish meal.
• Conclusion: Feeds normally on (A) Pyrethrum and tobacco and (B) Meat and fish meal (Option 1).

Correct option: (1) (A) and (B) only.
