Impact of Watermelon bud necrosis virus (WBNV) infected plants on the volatile emission pattern in cowpea plants

Pathogens, including tospoviruses, are known to manipulate the behaviour of vectors after virus acquisition by plants enhance transmission. Furthermore, as recently proven in maize chlorotic mottle pathosystem, vector's choice for virus-infected can change a preference noninfected uptake vector. A similar trend was observed cowpea - Watermelon Bud Necrosis Virus (WBNV) Thrips palmi (Karny) pathosystem. Similarly, no-choice bioassay, viruliferous T.palmi (carrying WBNV) settled preferentially more on healthy (56%) compared (47.3%), whereas non-viruliferous WBNV infected (58.67%) (44%). The changes thrips towards host before and may be due volatile cues. This study looked at headspace composition WBNV-infected that attract thrips. analysis revealed 1, 2-Propanediamine (0.62%) Tuaminoheptane (0.55%) from plants, well Tetradecane (0.35%) both have higher area percent than other volatiles. amine (53%) hydrocarbon (69%) groups organic compounds make up majority volatiles found plants. increased contact rates could transmission if feed them acquire pathogen prior dispersal recorded might useful vector management future.
