Question

Match List-I with List-II 

List-I		List-II
A	Muller's organ	I	Pedicel of antenna
B	Johnston's organ	II	Tympanum
C	Pearman's organ	III	Cicadas
D	Tymbal	IV	Hind coxae of Psocoptera

Choose the correct answer from the options given below:

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

Hint:

Johnston's organ is always located in the antennal pedicel (Segment 2). Tymbals are the classic sound-producing organs of cicadas. Knowing these two allows you to solve the match.

Answer 1

The Correct Option is C

Step 1: Understanding the Concept:
Insects possess specialized physiological and sensory organs for hearing, mechanoreception, sound production, and taxonomic differentiation.
Detailed Explanation:
Let us match the structures in List I with their descriptions in List II:
- (A) Muller's organ: This is a specialized auditory structure consisting of a group of scolopidia associated directly with the inner surface of the auditory Tympanum (II) in grasshoppers and locusts.
- (B) Johnston's organ: This is a collection of sensory cells located in the second antennal segment, known as the Pedicle of antenna (I). It functions as a mechanoreceptor to detect vibrations, wind speed, and sound.
- (C) Pearman's organ: This is a specialized, sound-producing/micro-sensory structure located on the Hind coxae of Psocoptera (IV) (booklice).
- (D) Tymbal: This is a specialized, drum-like sclerotized membrane used to produce high-frequency mating calls by male Cicadas (III).
Matching these gives: (A) - (II), (B) - (I), (C) - (IV), (D) - (III).

Step 2: Final Answer:
The correct matching sequence is represented by option (3).
