Abstract
Capsicum annuum is important vegetable and spice crop in India. Majority of the sucking pests in this crop are long lasting and cause more crop loss than borers and leaf feeders. The major key sucking pests are Thrips (Scirtothrips dorsalis Hood), Green peach aphid (Myzus persicae Sulzer), Cotton aphid (Aphis gossypii Glover) and Yellow mite (Polyphagotarsonemus latus Banks). Multimode of action is the speciality of botanicals. The bioassay studies were to explore the comparative evaluation of water extracts and hot water extracts of botanicals against sucking pests on Capsicum annuum in laboratory conditions. The botanicals Leaf powder of Sivanarvembu (Indigofera aspalathoides), Plant powder of Narrow leaved milkwort (Polygala elongata), Plant powder of Birthwort (Aristolochia bracteolata), Leaf powder of Green chirayta (Andrographis paniculata) and Leaf powder of Lippia (Phyla nodiflora) were tested against major sap feeders with three various concentrations of 1%, 3% and 5%. The observations were made on the mortality of test insects at 6h, 24h and 48h respectively. Two different types of bioassay viz., onplant and poison food bioassay were conducted. Results revealed that the Lippia 5% and green chirayta 5% showed with high mortality in both type of bioassays.
