Efficacy of Different Synthetic Insecticides against Citrus psylla Population Liviidae: Hemiptera at District Peshawar

Abstract

The study was conducted to check the efficacy of different insecticides against Citrus psylla at ARI Tarnab Peshawar during the year 2024. Randomized complete block design (RCBD) was used having five treatments including control via Malathion, Lambda Cyhalothrin, Pyriproxifen, Polytrin-c replicated three times. After first spray application lowest mean population was recorded in Polytrin-c followed by Lambda cyhalothrin and highest mean population was recorded in control. Second spray data indicated that lowest mean population was recorded in Lambda cyhalothrin followed by Polytrin-c and highest mean population was recorded in control. All the insecticides were influential in regulating the population of Citrus psylla, and revision of spray significantly reduced their occurrence. Lambda cyhalothrin and Polytrin-c proved to be highly effective and it should be sprayed twice with an interval of three weeks.
