Question

Given below are two statements, one is labelled as Assertion A and the other is labelled as Reason R
Assertion A: Inflorescence midge is a pest of mango.
Reason R: It can be controlled by summer ploughing of orchard, soil application of methyl parathion and spraying of dimethoate.
In light of the above statements, choose the correct answer from the options given below:

• A. Both A and R are true and R is the correct explanation of A
• B. Both A and R are true but R is NOT the correct explanation of A
• C. A is true but R is false
• D. A is false but R is true

Hint:

Remember inflorescence midge management:
- Summer ploughing: Destroys pupae
- Soil application: Methyl parathion
- Spraying: Dimethoate, malathion
- Cultural control: Remove and destroy infected inflorescences
- Integrated Pest Management (IPM) is recommended for sustainable control.

Answer 1

The Correct Option is A

Step 1: Understanding the Concept:
This question tests knowledge of mango pests and their management.

Step 2: Detailed Explanation:
Assertion A:
Inflorescence midge is indeed a pest of mango.
It is a small fly that lays eggs on the inflorescence, causing damage to flowers and fruits.
This statement is true.
Reason R:
Inflorescence midge can be controlled by:
- Summer ploughing: Destroys pupae in the soil.
- Soil application of methyl parathion: Kills pupae in the soil.
- Spraying of dimethoate: Controls adult flies and larvae.
These are effective control measures for this pest.
This statement is true.
Relationship between A and R:
R explains A by providing the control measures for the pest.
The reason correctly describes the management practices for inflorescence midge.
Thus, R is the correct explanation of A.

Step 3: Final Answer:
Thus, both A and R are true and R is the correct explanation of A, which corresponds to option (A).
