Toxicity of 96% chlorpyrifos TC, 98% imidacloprid TC, 93% thiamethoxam TC and mixed pesticides of chlorpyrifos with other two agents （D ＋ B, D ＋ S） to C. lanigera （Zehntner） were determined under laboratory cond...Toxicity of 96% chlorpyrifos TC, 98% imidacloprid TC, 93% thiamethoxam TC and mixed pesticides of chlorpyrifos with other two agents （D ＋ B, D ＋ S） to C. lanigera （Zehntner） were determined under laboratory conditions by leaf dipping method. The results showed that all of the pesticides had high toxicity with the order of thiamethoxam TC 〉 imidacloprid TC 〉 D ＋ B 〉 chlorpyrifos TC 〉 D ＋ S. The results provided theoretic basis for selecting suitable insecti- cides to control the C. lanigera （Zehntner）.展开更多

[Method] According to the outbreak characteristics of C. lanigera,multi-rotor unmanned aerial vehicle was applied for flying control test. Referred to the spraying characteristics of multi-rotor unmanned aerial vehicle,two kinds of microcapsule pesticides,ALV-1501 and ALV-1502,and two kinds of spraying additives,SPA-01 and SPA-02,were designed to control C. lanigera. [Result] The control effect of ALV-1501 at the dose of 2. 25 L/hm;was 60. 02% at 1 d post administration and 54. 14%at 5 d post administration; the control effects of ALV-1502 at the dose of 2. 1 L/hm2 were 76. 35% and 81. 35% at 1 and 5 d post administration,respectively.Compared to individual pesticide,the control effects of ALV-1501 were improved 1. 42-1. 47 times and 1. 16-1. 14 times by adding 0. 6 L/hm;SPA-01 and SPA-02 in pesticide liquid,respectively. The control effects of ALV-1502 were improved 1. 23-1. 25 times and 1. 15-1. 16 times by adding 0. 6 L/hm2 SPA-01 and SPA-02,respectively. The control effects against C. lanigera at three flying speeds of 3,5 and 8 m/s were 99. 72%-99. 97%,81. 6%-99. 81% and63. 52%-68. 77%,respectively. [Conclusion]The results will provide a reference for application of multi-rotor unmanned aerial vehicle in prevention and control of C. lanigera in sugarcane field.展开更多
