abstract
The present study was conducted in New Developmental Farm (N.D.F), The University of Agriculture Peshawar during 2014-2015 to determine the prevalence of insect pollinators in systemic insecticide treated and densely grown pea fields. Insects were observed on each second day at morning (9:00 am - 12:00 pm) and evening (3:00 pm- 5:30 pm) of the flowering season i.e. 16/2/2015 to 28/3/2015. The experiment was comprised of four treatments, that were Recommended plant population (T1), Dense plant population (T2), Recommended plant population treated with Imidacloprid insecticide (T3) and Dense plant population treated with Imidacloprid insecticide (T4). Each treatment in each replication was given a time of 5 minutes such that to record the density of insect pollinators. It was observed that highest total numbers of insect pollinators in morning and evening both during the whole observation period was recorded in T3 with a value of 515 pollinators having a percentage of 28, followed by T4 with a value of 497 pollinators having a percentage of 27. Lowest insect pollinators were reported in T2 and T1 with values of 416 and 419 having percentages of 22 and 23 respectively.
