| Abstract: |
| The elm aphid, Tinocallis platani (Kaltenbach) (Hemiptera: Aphididae), is one of the most important pests in the urban green spaces that its damage is severely important on the elm trees. Currently, the general method to control the pest is using the chemical pesticides, which is caused to resistance of the elm aphid to many common insecticides. In addition, the indiscriminate usage of insecticides has led to damage to the natural enemies of the aphids. Therefore, use of safe and biocompatible botanical pesticides is very noticeable. Salpipest® (EC 20%) is a biocompatible botanical pesticide that is recommended to control white fly, Trialeurodes vaporariorum Westwood (Hemiptera: Aleurodidae). In this study, contact toxicity of Salpipest, Salpipest + Volk oil (0.025%) and Salpipest + Volk oil (0.05%) was investigated on the second instar nymph of T. platani. The lethal effect of Salpipest was examined using the dipping method and then the mortality was recorded 24 h after treatment. The experiment was performed at a standard environmental conditions (25±1ºC, 70±5% RH and L:D 16:8 h). Also, control treatments were considered at the same conditions with water and Volk oil. Data probit analysis demonstrated that the lethal concentration to cause 50% mortality (LC50) and their 95% confident limits of Salpipest, Salpipest + Volk oil (0.025%) and Salpipest + Volk oil (0.05%) were evaluated 110.90 (88.58-136.54), 3.76 (3.40-4.15) and 3.16 (2.20-7.65) ppm, respectively. According to the results, the toxicity of Salpipest + Volk oil (0.025%) and Salpipest + Volk oil (0.05%) were significantly higher than Salpipest. However, no significant differences were found between Salpipest + Volk oil (0.025%) and Salpipest + Volk oil (0.05%). Hence, the present results indicate that Salpipest + Volk oil is a suitable botanical pesticide to control the elm aphid. However, further assessment are needed to determine the toxicity effect of Salpipest on T. platani in the urban spaces. |
