| 中文摘要: |
| 2006年和2007年，对桃李间作果园和单作桃园害虫和天敌进行了调查。通过对主要害虫山楂叶螨（Tetranychus viennensis Zacher）和梨小食心虫［Grapholitha molesta (Busck)］种群动态的比较分析，发现桃李间作可以增加桃树上山楂叶螨的种群数量；从空间分布的角度发现，当梨小食心虫密度高时桃李间作可以降低梨小食心虫的空间分布聚集程度。天敌功能团的典范对应分析表明桃李间作对天敌群落的影响是不稳定的。 |
| 英文摘要: |
| The pests and predators in plum/peach intercropping orchards and plum or peach orchards were investigated in 2006 and 2007. The results showed that the red spider mite, Tetranychus viennensis Zacher, in the plum/peach intercropping orchards was more abundant than that in the peach orchards. The intercropping of plum and peach had diluted the assembly of the oriental fruit moth Grapholitha molesta (Busck) when many moths were distributed in the plum/peach intercropping orchards. The effects of plum/peach intercropping on the natural enemy community were insecure according to canonical correspondence analysis on the natural enemy guilds. |
