本文研究了有机苹果园常用的6种杀菌剂,包括农抗120、绿乳铜、高锰酸钾、大生M-45、成标和多菌灵对果园重要害虫苹果黄蚜Aphis citricola van der Goot及其天敌异色瓢虫Harmonia axyridis Pallas死亡率的影响.结果表明,这6种杀菌剂使用喷雾和浸叶饲喂法对蚜虫的死亡率均有一定的影响,但校正死亡率均小于21%.喷雾处理和二次中毒处理对瓢虫幼虫的死亡率均无显著影响.上述结果说明6种供试杀菌剂的常用浓度对蚜虫有较低的致死率,而对其天敌异色瓢虫则是安全的,因此我们推测上述杀菌剂的常规使用不会对果园昆虫的群落结构造成重大影响.

Impacts of six common germicides on mortality of the pest in organic apple orchard Aphis citricola and its natural enemy, Harmonia axyridis were tested. The results showed that all of the six germicides had toxicity to A. citricola whatever treated by spray or feed methods, however, the corrected mortalities were always less than 21%. The germicides did not increase mortality of larval H. axyridis treated by spray method or feeding with aphids treated by germicides. The above results indicated that the six germicides used in present study did not induce a high mortality to A. citricota and did not affect the mortality of H. axyridis either. Therefore, we concluded that the using of above mentioned germicides did not affect the insect community structure very much in apple orchard.
