Biorational Management of Pulse Beetle (Callosobruchus chinensis L.) in Gram Seed

Abstract: The pulse beetle, Callosobruchus chinensis is one of the major pests in stored pulse causes 40-50% losses of pulses in storage. Experiments were conducted to study the efficacy of some selected biorational insecticides on percent mortality of beetle, percent weight loss of seeds, no. of eggs laid per female, percent hatchability, larval duration, pupal period and adult longevity of pulse beetle, Callosobruchus chinensis under laboratory condition. Among the different botanicals, neem oil (77%) was found the mo… Show more

“…The experiment on modified atmosphere studies using elevated levels of CO 2 was carried out against C. chinensis in the Department of seed science and technology, OUAT, Bhubaneswar in specially designed airtight containers and the required concentration of CO 2 was released into these containers with the help of carbon dioxide cylinder fitted with an outlet tube containing a nozzle and a needle. Five pairs of freshly emerged adults were transferred to airtight plastic containers of 250 g capacity separately and directly exposed to five different concentrations of CO 2 viz., 20%, 40%, 50%, 60% and 80% with six different exposure periods viz., 30,60,90,120,150 and 180 minutes and each treatment was replicated thrice (Hasan et al, 2020). The chickpea seeds were observed after 2, 4 and 6 months of treatment for each concentration of CO 2 and the data on fecundity, adult emergence, seed damage and weight loss due to damage, moisture content and germination per cent were recorded and analysed statistically.…”
