Abstract
Experiment conducted at The University of Agriculture Peshawar in winter 2022 aimed to investigate the density of sucking insect pests on canola crops. Data was collected on the population of aphids, whitefly, jassids and thrips, as well as their associated natural enemies. The findings revealed that the highest infestation of aphids occurred during the 2nd week of November, with 3.1 aphids per leaf. This was followed by whitefly, jassids and thrips, with population densities of 2.8, 2.7 and 2.3 per leaf respectively. Aphids exhibited the highest population density among the four sucking insect pests, while thrips had the lowest. Significant differences were observed in the mean numbers of predators between the first two observations, particularly in the population densities of ladybird beetles, green lacewing and syrphid flies at the study site.
