Effect of insecticides and food source on progeny production of Rice weevil, Sitophilus oryzae; Insecticides (malathion, spinetoram, and lambda-cyhalothrin) applied to jute bags containing three commodities (maize, wheat, and rice). Adult weevils were continuously exposed for 21 days, followed by the removal of live and dead parental adults. Progeny reduction was assessed at 60 days post-exposure. The same colour bars sharing a common letter indicate non-significant difference in progeny reduction over control (Tukey’s HSD test).
