Question

Aceria tulipea is a vector of
(A) Bean yellow mosaic
(B) Wheat streak mosaic
(C) Peanut bud necrosis virus
(D) Cowpea mosaic virus

• (A) and (B) only.
• (A) and (C) only.
• (A) and (D) only.
• (B) only.

Hint:

Eriophyid mites are tiny and cigar-shaped. Remember: Aceria = Wheat Streak Mosaic. They are often dispersed by wind.

Answer 1

The Correct Option is D

Step 1: Understanding the Concept:
Mites are not insects; they belong to the class Arachnida. However, certain families like Eriophyidae (gall mites) are important vectors of plant viruses.
Detailed Explanation:
Aceria tulipeae, commonly known as the Wheat Curl Mite, is a microscopic, four-legged eriophyid mite.
It is the primary and most significant vector of the Wheat Streak Mosaic Virus (WSMV).
The mite transmits the virus in a persistent manner. It acquires the virus as a nymph while feeding on infected wheat or grasses and retains the ability to transmit it throughout its life.
The virus causes yellow streaks on leaves, stunting, and failure to head in wheat crops.
- Bean yellow mosaic is transmitted by aphids.
- Peanut bud necrosis virus is transmitted by thrips.
- Cowpea mosaic virus is transmitted by beetles.
Therefore, Aceria tulipeae is specifically associated with Wheat Streak Mosaic.

Step 2: Final Answer:
Aceria tulipeae is a vector of (B) only.
