| 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 <0.01, F = 367.71; df = 7; P <0.01, F = 121.11; df = 7; P <0.01 for the first, second and third week after the experiment, respectively). This result was also confirmed by a decrease in the number of eggs laid by females DPH (F= 53.89; d.f=7; P< 0.01). All treatments significantly diminished the egg laying of DPH compared with control. The two of non-chemical treatments, Kaolin and coconut oil soap showed high efficiency in decreasing population of DPH without destructive effects on the environment, we can suggest these two eco-friendly products be used safely against Dubas bug. In addition, kaolin may contribute in decreasing the sunburn effects which is suggested to be studied by further research. | ||
