摘  要：
1997年7月至2000年6月在浙江黄岩进行了不同药剂防治方案对某些柑桔病虫害的防效及成本的比较试验。结果显示,与果农常规的以使用化学合成农药为主的防治方案相比,采用以使用机油乳剂和铜制剂为主的防治方案既能使柑桔病虫害得到有效的控制,又使果园生态得到改善、天敌群落密度及其对害虫的自然控制力得到恢复,进而使害虫得到可持续的控制。实施该防治方案的初期成本可能会稍高于常规防治方案,但持续实施后,天敌群落密度增加,对害虫的自然控制力提高,需要用药的次数减少,一年后其防治费用会降至常规防治方案之下。

摘  要：
A series of comparative tests of two control progiams against citrus pests were carried out since July. 1997 to June. 2000 in citrus orchard in Huangyan City, Zhejiang Province. The results showed that the citrus pests can be more effectively kept under control by adopting the control program spraying mainly with petroleum spray oils (PSO) and copper germicides, the ecological environment in citrus orchard was improved, the density and natural control level of natural enemies was recovered. This program was considered beneficial to the implementation of citrus pests sustainable management, comparing with conventional control program spraying mainly with synthetic pesticides. Owing to the expensive price of high precision PSO, the cost of the control program was rather high at the beginning of practice, but it was progressively reduced along with the enhancement of density and natural control level of natural enemies and the decrease of spraying times, and stepped down to the level lower than that of conventional control program one year later.
