Description Tomato is one of the important vegetable crops grown in Karnataka. Tomato crop
suffers from several biotic stresses among the important pest of this crop whitefly is one
of the most severe pest leading to heavy losses of the crop. Among the tomato cultivars,
longest life cycle of whitefly was recorded on Arka Abha; however on Arka vikas the
least life cycle period was recorded. The highest adult male and female longevity were
recorded on Arka abha and followed by Arka vikas and Avinash –II. Among the weed
species, longest life cycle of whitefly was recorded on Euphorbia spp followed by wild
radish. The highest adult male and female longevity was observed on Euphorbia spp.
followed by wild radish. Identification of whitefly biotype through RAPD-PCR analysis
of whiteflies revealed the presence of B biotype in Bangalore area on tomato. Among
these predator and parasitoids, Macrolophus pygmaeus and Axinoscymnus puttarudriahi
and Encarsia transvena (Timberlake) found in large numbers and can be used to control
this pest. Isolated the entomopathogenic fungi like Beauveria bassiana, Verticillium
lecanii, Metarhizium anisopliae and Paecilomyces farinosus from the infected whitefly.
In the varietal preference, the most preferred tomato cultivars for oviposition activity of
B. tabaci were Pusa ruby, PKM-1 and Arka vikas. Whereas Nandi, Sankranthi, and
Vybhav were least preferred cultivars. Vybhav and Nandi cultivars were relatively
resistant to B. tabaci. In the border crops, tomato- baby corn combination was best
followed by tomato – cowpea border crop resulted in reduced whitefly population
incidence in the main field. Among the botanicals Neem oil, NSKE and Pongamia oil
were found to be effective in bringing down whitefly population. Vertical and cylindrical
yellow sticky trap above the ground level proved to be effective monitoring devices of
whitefly. Among the entomopathogenic fungi Beauveria bassiana and Verticillium
lecanii was highly effective in the laboratory.
