At first, attack area of AAM and kill probability of every characteristic point are obtained by combining trajectory calculation with kill probability calculation. Then, coordinates of a fire point relative to standard kill probability value in terms of standardization method are found. At last, equivalent kill probability curve equations are formulated by means of curve fitting method.展开更多

[Methods] Based on the investigation of termite damage to trees in Lijiakeng Village, Longmen Ancient Town, Luobu Ancient Town and Huanglin Village in Zhejiang Province, the indoor toxicity test of powder and bait was conducted to analyze the termite control effect of different agents. [Results] The experiment showed that 5% Fipronil powder was relatively better than 4.8% Imidacloprid powder, and 1.3% Fipronil was better than 2.5% Hexaflumuron. [Conclusions] It was found that the termite bait station combined with powder spraying and baiting has high social value for termite control in rural areas.展开更多
