Abstract

Bud necrosis disease (BND), caused by peanut bud necrosis virus (PBNV) is an important disease of peanut (Arachis hypogaea L.) in India. Studies with Thrips palmi, Frankliniella schultzei and Scirtothrips dorsalis showed that only T. palmi transmitted PBNV. T. palmi acquired the virus as larvae, requiring a 5-min acquisition period, but only transmitted it as adults. Adults needed an inoculation feeding period of > 1 h to transmit, and the majority transmitted the virus throughout their life. In field situations, a virus-susceptible peanut genotype had higher densities of T. palmi than resistant genotypes. In peanuts, S. dorsalis was the dominant foliar species, T. palmi was on foliage and flowers, and F. schultzei was mostly on flowers. Several common weed species in peanut were infected with PBNV and were colonized by T. palmi.
