Among avian pests, house sparrow caused serious depredations, not only
to seeds, but also seedlings of various crops particularly in the
organic farming. Different mechanical and chemical ways have been
reported to manage these losses all over the world. The present study
was aimed to investigate the efficacy of two bird repellents namely
methylanthranilate and anthraquinone to manage the depredations of wheat
seeds and seedlings against house sparrow in captivity. For this
purpose house sparrows were offered with treated and untreated seeds and
seedlings of wheat in two aviaries. By providing treated seeds and
seedlings with these repellents, the relative effectiveness was
appraised by comparing the consumed and unconsumed seeds and seedlings.
Feeding responses of these birds against different doses of these
repellents were investigated with the help of the closed circuit cameras
adjusted in the aviaries. During the whole experiment among trial and
control group highly significant differences (P<0.01) were seen in
both seeds and seedlings cases.
The mean consumption of wheat seeds
treated with anthraquinone and methylanthranilate was 24.04±2.50 and
26.28±2.02, respectively, which depicted anthraquinone is relatively
good repellent than methylanthranilate and a significant difference
(P<0.05) was also observed. Different concentrations of both
repellents showed a non-significant (P>0.05) variance when wheat
seeds and seedlings were offered to house sparrows. House sparrows were
influenced more quickly by consuming wheat seeds and seedlings treated
with both repellents. Sparrows displayed noticeable head-shaking and
feather ruffling behavior by consuming the treated seeds and seedlings.
