Which one of the following pair is not correctly matched in the term of Disease and Insect (Vector)?
A. Banana bunchy top ⇔ Banana aphid
B. Cotton leaf curl ⇔ White fly
C. Katte disease of cardamom ⇔ Aphid
D. Groundnut bud necrosis virus ⇔ Moth
Answer: Option D
Solution(By Examveda Team)
A. Banana bunchy top ⇔ Banana aphidBanana bunchy top is caused by banana bunchy top virus (BBTV), a plant virus transmitted by a small black insect called the banana aphid (Pentalonia nigronervosa).
B. Cotton leaf curl ⇔ White fly
Cotton leaf curl disease (CLCuD) is a viral infection of cotton and other susceptible host plants that are transmitted by Silverleaf whitefly (Bemisia tabaci).
C. Katte disease of cardamom ⇔ Aphid
The plants infected by mosaic or Katte can survive for many years and act as the source of inoculum. The virus is transmitted through the aphid vector Pentalonia caladii.
D. Groundnut bud necrosis virus ⇔ Moth is not correctly matched.
Spread of this virus in peanut/groundnut is mostly monocyclic, and disease incidence in this host depends on infection by thrips, not by moths that acquire the virus from other crops or weed hosts.
