Black legume aphid, Aphis craccivora Koch, is one of the most important pests on legumes and about 80 plant families. To control of this pest different chemical pesticides were used by farmers. In this research, a test was conducted in order to reduce the chemical pesticide application and the possibility of using the herbal pesticide Palizin. In this research toxicity of Palizin SL65% (Containing coconut oil soap and peppermint extract and eucalyptus extract) in three concentrations (2500, 1250 and 833 ppm) compared with the chemical pesticides imidacloprid (SC35%, 400 ppm), pirimicarb (WP50%, 700 ppm) and spirotetramat (SC 10%, 700 ppm) in the laboratory conditions on fifth instar nymph of this pest was assesed. For each treatment (concentration) six replications and within each replication, ten insects were placed. The leaf dipping method was performed in each solution for three seconds, then the leaves and treated insects were transferred to petri dishes on wet filter paper in the incubator at (25±1°C, 60±5% relative humidity (RH) and 16:8, D: L photoperiod conditions). The percentage of mortality was calculated at 24, 48 and 72 hours after application of the treatment. The results showed that Palazin pesticide with the concentrations of 2500 ppm and 1250 ppm at 24 hours after treatment caused 100% mortality and with the concentration of 833 ppm at 24 and 48 hours after treatment respectively caused 76.67 and 100% mortality. Among the chemical pesticides used, pirimicarb with 70, 100, and 100% mortality was better performance than spirotetramat with 63.83, 80.57, and 90%, and imidacloprid with 10, 43.33, and 73.13% mortality respectively at 24, 48 and 72 hours. Also, control treatment (water) caused 3.33, 13.33, and 46.68% mortality, respectively at test times. Therefore, according to the results obtained in this study, herbal pesticide Palizin can be application to produce healthy and organic products for control black legume aphid.
