Abstract:
Stored grain products are damaged by various types of insects during preservation of T. castaneum and lesser grain borer are most dangerous insect of preserved food. Rhyzopertha dominica is inner feeder and influences the wide variety as good as high quality of grains. Spinosad insecticide are very potent to manipulate the stored grain pest. Current research work was performed in the Department of Entomology, University of Agriculture, Faisalabad. Five concentrations 0.01%, 0.02%, 0.03%, 0.04%, 0.05% along with one control treatment of Spinosad was formed in hundred ml of purified water from standard dilutions and 2, 4, 6, 8, 10% concentrations of each plants were prepared. Treatments were applied to check their possible toxic effects against T. castaneum and R. dominica. The data were recorded after 24, 48 and 72 hours, treatment means were compared with the help of (THSD) test. Spinosad gave maximum mortality 89.77% as compared to plant extracts lemon grass and tobacco 38.55% and 40.00% against lesser grain borer. Spinosad gives maximum mortality 87.27% as compared to plant extract lemon grass and tobacco 34.55% and 29.09% against red flour beetle.
