Y- Tube Olfactometer Studies of Sitophilus Oryzae L. Feeding on Split Pulses
نویسندگان
چکیده
Behavioural responses of S. oryzae to odours/volatiles from sorghum, red gram, chick pea, black gram, green gram, fried gram and lentil were compared in Y-tube olfactometer bioassay. Results indicated that sorghum populations were more attracted towards sorghum followed by split pulses. Whereas pulses populations were more attracted towards red gram followed by green gram, chick pea, black gram, lentil and fried gram. In sorghum populations the maximum preference was observed in sorghum (70 and 80%) followed by red gram (40 and 50%) in uninfested and infested grains respectively. Whereas pulses populations the maximum preference was observed in red gram (80 and 90%) followed by green gram (70 and 80%) in uninfested and infested grains respectively.

BIOLOGICAL ACTIVITY OF ESSENTIAL OILS FROM LEAVES AND FRUITS OF PEPPER TREE (Schinus molle L.) TO CONTROL RICE WEEVIL (Sitophilus oryzae L.)
Rice weevil (Sitophilus oryzae L.) is a primary insect pest of stored grain. The development of resistance resulted in the application of synthetic insecticides. In recent years many plant essential oils have provided potential alternatives to currently used insect control agents. The Brazilian pepper tree (Schinus molle L. var. areira (L.) DC.) (Anacardiaceae) has different biological properti...
