Question

Match List-I with List-II

List-I		List-II
A	Indian meal moth	I	Fluttering during courtship
B	Angoumois grain moth	II	The adult moth is larger than other moths
C	The almond moth	III	Initial infestation takes place in the grain at field itself at milk stage
D	Rice moth	IV	The larva first feeds on germ point

Choose the correct answer from the options given below:

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

Hint:

Remember that Sitotroga cerealella is famous for cross-infestation, meaning it begins its damaging infestation in the field itself at the milk stage of the grain.

Answer 1

The Correct Option is A

Step 1: Understanding the Concept:
Storage entomology deals with insect pests that damage stored grains and agricultural products.
Each species of stored product insect exhibits distinct behavioral, physiological, and morphometric traits that help in their diagnosis and management.

Step 2: Detailed Explanation:
Let us analyze the biological matching of the listed stored product moths:
1. Indian meal moth (Plodia interpunctella): During courtship, the males exhibit a characteristic fluttering behavior (rapid wing vibration) to disperse pheromones and court females. Thus, (A) matches with (I).
2. Angoumois grain moth (Sitotroga cerealella): This is a primary stored grain pest that can attack crops both in the field and in storage. The initial infestation typically occurs in the field itself on the standing crop when the grains are at the milk/dough stage. Thus, (B) matches with (III).
3. Almond moth (Cadra cautella): The young larva of this pest has a highly specific feeding preference, where it first attacks and feeds on the germ point (embryo) of the grain, leaving the endosperm intact initially. Thus, (C) matches with (IV).
4. Rice moth (Corcyra cephalonica): Among the common stored grain lepidopterans, the adult of the rice moth is significantly larger in size compared to other small moths like the Angoumois grain moth or the almond moth. Thus, (D) matches with (II).
This pairing perfectly corresponds to: (A) - (I), (B) - (III), (C) - (IV), (D) - (II).

Step 3: Final Answer:
Therefore, the correct matched sequence is option (A).
