Peanut bud necrosis virus (PBND) is transmitted by:
(A) Aphis gossypii and Myzus persicee
(B) Aphis maydis and Toxoptera graminum
(C) Thrips palmi and Frankimella schultzei
(D) Planococcoides njalensis and Pentalonia nigronervosa

Answer 1

The Correct Option is C

PBND is transmitted by thrips species (Thysanoptera)
Primary vectors:
Thrips palmi (most efficient)
Frankimella schultzei (secondary vector)
Aphids and mealybugs cannot transmit this tospovirus
