| 中文摘要: |
| 通过田间观察及气象因子分析,龙眼长跗萤叶甲成虫的发生与龙眼抽梢时间密切相关,而与温湿度无密切关系。该虫在广西南宁一年出现两个高峰期:3月下旬至4月中旬,6月下旬至9月下旬。室内外药剂筛选结果表明,90％晶体敌百虫、80％敌敌畏乳油、2.5％溴氰菊酯乳油、10％氯氰菊酯乳油、20％速灭杀丁乳油、48％乐斯本对龙眼长跗萤叶甲成虫有较好的防治效果。 |
| 英文摘要: |
| Based on field investigations and analysis of meterological factors, the occurrence of Monolepta occifuvis Gres-sitt et Kimoto adults was closely related to Longan growth period but, not to temperature and humidity. There were two emergense peaks a year i.e. later March to middle April and later June to later September. The effectiveness of insecticides such as 90% trichlorphon, 80% dichlorvos EC, 2.5% dectamethrin EC, 10% cypermethdrin EC, 20% sumicidin EC, 48% chlorpyrifos EC, were tested in the Laboratory and fields. The results showed that they were all effection in con-teallmy the adults of Monolepta occifuvis. |
