Question

Match List I with List II
List I
A. Abate
B. Bromadiolone
C. Sulphur
D. Allethrin
List II
I. Mosquito larvae
II. Mosquito adults
III. House mice
IV. Dust mites
Choose the correct answer from the options given below:

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

Hint:

Remember these chemical uses: - Abate (Temephos) is a standard mosquito larvicide. - Bromadiolone is a common rodenticide for mice. - Allethrin is the active ingredient in many mosquito coils.

Answer 1

The Correct Option is A

Step 1: Understanding the Concept:
Chemical control of pests involves using specific pesticides targeted against target organisms, including insects, mites, and rodents.

Step 2: Detailed Explanation:
Let us match each chemical in List I with its target organism in List II:
- A. Abate (Temephos): This is an organophosphate larvicide widely used in water treatment programs to control I. Mosquito larvae by preventing them from developing into adults.
- B. Bromadiolone: This is a second-generation anticoagulant rodenticide used to control rodent pests, including III. House mice.
- C. Sulphur: Elemental sulfur is a traditional pesticide that serves as an effective acaricide/miticide to control agricultural and household mites, such as IV. Dust mites.
- D. Allethrin: This is a synthetic pyrethroid compound used primarily as an adulticide in household mosquito coils and vaporizers to knock down and kill II. Mosquito adults.
This gives the match: A-I, B-III, C-IV, D-II.

Step 3: Final Answer
The correct option is (A).
