Abstract:

The toxicity and residual effects of malathion, dimilin and "Neem extract factor B" (NfB) were tested against adults of rice weevil, Sitophilus oryzae (L.). The LD50's by impregnation method were 1.04, 28.0 and 86.46 igicm2 for malathion, dimilin and NfB, respectively. The highest concentration used (malathion 0.05%, dimilin 0.25%, NfB 0.5%) were effective upto 7-10 days after treatment.
