Abstract :
Chemical application is the most common practice widely used against date palm hopper (DPH), Ommatissus lybicus de Bergevin (Hem.: Tropiduchidae). Herein, we studied the efficiency of non-chemical approaches in suppressing DPH damage in the field condition. The study was carried out in a Randomized Complete Block design (RCB) with eight treatments, spraying micronized Kaolin (5% SP); Volck oil (1.5% EC); Citogate oil (1.5% EC); coconut oil soap (1.5% EC); yellow cards (six cards per 10 mature leaves and four cards per10 mature leaves); Diazinon (60% EC) and control, replicated three times. Results revealed that all treatments caused a sharp decrease in population of DPH (both adults and nymphs) up to the end of the third week and Diazinon was the most influential treatment (F = 623.92; df = 7; P
