Match the following common names of the insect pests with their... | Agrigyan

• Ellis & Roberts Seed Viability Equation:

• Components:
• $v$: Probit percentage viability of the seed lot after storage time $p$.
• $K_i$: Initial viability constant, which is a genotype- and lot-specific parameter representing the physiological quality and potential longevity of the seed lot before entry into storage.
• $\sigma$: Standard deviation of seed lifespans, which depends on storage moisture content ($m$) and storage temperature ($t$).
• Conclusion: When a seed lot is transferred to a different storage environment (different temperature or RH), $\sigma$ changes, but the initial inherent seed quality $K_i$ remains constant and unaffected. (Correct answer: Option 2)

• Scientific Identification of Major Stored Grain Pests:
• Red Flour Beetle: Scientific name is Tribolium castaneum (Herbst) (Coleoptera: Tenebrionidae), a major secondary storage pest of milled cereals $\rightarrow$ (II)
• Saw-Toothed Grain Beetle: Scientific name is Oryzaephilus surinamensis (L.) (Coleoptera: Silvanidae), characterised by 6 tooth-like projections on each side of the prothorax $\rightarrow$ (IV)
• Rice Weevil: Scientific name is Sitophilus oryzae (L.) (Coleoptera: Curculionidae), a primary pest with a prominent rostrum possessing round snout $\rightarrow$ (I)
• Lesser Grain Borer: Scientific name is Rhyzopertha dominica (Fabricius) (Coleoptera: Bostrichidae), characterized by a deflexed head concealed beneath a tuberculate pronotum $\rightarrow$ (III)
• Systematic Match: (A)-(II), (B)-(IV), (C)-(I), (D)-(III) corresponds to Option 2.

Correct option: (2) (A) - (Il), (B) - (IV), (C) - (1), (D) ~ (ttl)
