    abstract = {This study aimed to assess the effectiveness of chemical insecticides
against canola aphids during the winter of 2019 at The University of
Agriculture Peshawar. Treatments including Cypermethrin @ 3ml/lit,
Indoxacarb @ 0.5 ml/lit, Bifenthrin @ 2.5 ml/lit, lambda‐cyhalothrin @
1.5‐2 ml/lit and a control (tap water) were applied four times monthly at
7‐day intervals. Aphid population data were recorded, with the highest
infestation (3.1 Aphids leaf<sup>‐1</sup>) observed during the 2<sup>nd</sup> week of November.
Results indicated that lambda‐cyhalothrin resulted in the lowest mean
infestation (3.74±0.36), followed by bifenthrin (3.95±0.32), indoxacarb
(4.35±0.28) and cypermethrin (4.55±0.28). Furthermore, the maximum
yield (16.00±0.49 ha<sup>‐1</sup>) was obtained from lambda‐ cyhalothrin‐treated
plots, while the minimum yield (7.17±0.43 ha<sup>‐1</sup>) was recorded in the
control group. The highest mortality rate of 100% was achieved by
lambda‐cyhalothrin and cypermethrin after 72 hours of testing. Based on
these findings, further investigations into the potential side effects of
synthetic insecticides are recommended to better understand their
impact on the ecosystem.}
