Abstract
In this article, life table parameters of the
yellow tea thrips, Scirtothrips dorsalis Hood (Thysanoptera: Thripidae),
were studied on three selected tea cultivars viz., TV1, TV17 and TV23 in laboratory condition. The study revealed that
the net reproductive rate (R0) was maximum on TV17 and minimum on
TV23. The intrinsic rate of increase (rm), finite rate of increase (λ) and
weekly multiplication rate (erm.7) were maximum on TV1 and minimum
on TV23. The doubling time was maximum for the population on TV23 and minimum
on TV1. The results indicated that the adult reproductive parameters were
affected by the three different cultivars of tea, which could be applied in tea
thrips control management.
