Question

Match List-I with List-II:

• A. (A)-(I), (B)-(II), (C)-(III), (D)-(IV)
• B. (A)-(II), (B)-(I), (C)-(IV), (D)-(III)
• C. (A)-(II), (B)-(I), (C)-(III), (D)-(IV)
• D. (A)-(I), (B)-(III), (C)-(IV), (D)-(II)

Hint:

Encarsia species are important biological control agents against whiteflies, reducing pesticide use in integrated pest management.

Answer 1

The Correct Option is C

Rugose spiralling whitefly: Controlled by Encarsia guadeloupae (A
II)
Spiralling whitefly: Primary parasitoid is Encarsia noyesi (B
I)
Silverleaf whitefly: Effectively managed by Encarsia inaron (C
III)
Coconut whitefly: Targeted by Encarsia sophia (D
IV)

Answer 2

Host-specificity elimination:
Each Encarsia species listed is a specialist parasitoid associated with one particular whitefly host, so the correct pairing can be found by matching known host records rather than memorising a table order. Encarsia guadeloupae is documented specifically as a parasitoid of the rugose spiralling whitefly, while Encarsia noyesi is the recorded parasitoid of the ordinary spiralling whitefly. Encarsia inaron is a well-known parasitoid used against silverleaf whitefly populations, and Encarsia sophia has been recorded parasitising the coconut whitefly. Matching each named parasitoid strictly to its documented host, rather than the other way around, converges on the same final set of pairs.
The correct matching is A-(II), B-(I), C-(III), D-(IV).
