| 中文摘要: |
| 利用胡瓜钝绥螨控制柑桔全爪螨和锈壁虱 ,研究结果表明 ,在不同生态区域胡瓜钝绥螨释放量为 90万头 /hm2,30d后防效可达 85%～95% ,控制害螨期长达 6个月 ,减少农药使用量40%～60%。生防园果实商品价值提高约1000元/667m2。本文还对在不同树龄、不同生态条件下使用捕食螨的适期、比例及配套技术等进行了研究 |
| 英文摘要: |
| The tests of predatory Amblyseius cucumeris to control Panonychus citri and Phyllocoptruta oleivora were studied in laboratory and fields in Fujian Province. Results showed that the control efficacy of A. cucumeris to the mites on citrus trees was 85%-95% with its release amount 900 000 larva/hm2 in different ecological areas after 30 days, and the control time could last six months. It could be decreased the chemical pesticides dose of 40%-60%, and the commercial value of the fruit in biocontrol citri orchard was better than that of the control. The output value increased RMB 15 000 yuan/hm2 . The optimum period of controlling two mites in different age of trees, ecological conditions, the rate of release amount of A. cucumeris and controlling release syetem were also studied in this paper. |
