The leaves, bark and seeds of Bakain (Melia azadarach) and Leaves,
bark of Ak (Calatropis procera) were tested for their deterrent/repellency
in powder form against Rhyzopertha dominica
F in wheat grain. The data showed that all of the treatments i.e. powders of Leaves,
bark and seeds of Bakain and Leaves, bark of Ak significantly
deterred/repelled the tested insect (R. dominica) in grains compared
to control. Best results were obtained with the application of bakain's bark powder with
98.95 percent insect deterrent/repellency of the insect, followed by powder of Ak's leaves
and bark of Ak with 89.25 and 86.50 percent deterrent/repellency of R. dominica
respectively. Seed of bakain with 73.75 percent insect deterrent/repellency
was found significantly least effective, followed by leaves of bakain with 82.50
percent repellency of the tested insect.
