| 摘要: |
| 在广西柳州市选择危害街道或庭院绿化树白玉兰(Michelia alba DC.)和火力楠(Michelia macclurei Dandy)的丽绵蚜(Formosaphis micheliae Takahashi),于危害期用40%氧化乐果乳油(原液,15倍液和500倍液)和80%敌敌畏乳油(原液)进行刮皮涂干防治试验。结果表明,40%氧化乐果乳油原液刮皮涂干防治效果达94%以上,来年该虫的复发率仅8.8%;40%氧化乐果乳油15倍稀释液防治效果可达到90%以上,来年该虫的复发率达87%。40%氧化乐果乳油500倍稀释液和80%敌敌畏乳油原液防治效果较差,仅为28%和25%。这种40%氧化乐果乳油刮皮涂干防治丽绵蚜方法,可减少化学药剂对环境的影响,而且方法简便,成本低,效果好,适宜在人为活动较频繁的公园、机关大院、校园、庭院白玉兰被害木推广使用。 |

| Abstract: |
| Formosaphis micheliae Takahashi that harms Michelia alba DC and Michelia macclurei Dandy of kerbside or courtyard afforest tree in Liuzhou, Guangxi was selected and prevention and cure test is carried out, using 40% oxidation Dimethoate emulsifiable (primary liquid fifteen times liquid,five hundred times liquid) and 80% dichlorvos emulsifiable (primary liquid) in its harmful period. The results show that 40% oxidation Dimethoate emulsifiable primary liquid is put into scrape-off-bark and dry test, their effect being up to 97% and the insect pest recurrence rate being only 8.8% in the coming year. The effect of 40% oxidation Dimethoate emulsifiable fifteen times liquid is over 90%, the insect pest recurrence rate being 87%. The effect of 40% oxidation Dimethoate emulsifiable five hundred times liquid and 80% dichlorvos emulsifiable primary liquid is only 28% and 25%. The scrape-off-bark and dry test method on 40% oxidation Dimethoate emulsifiable primary liquid can reduce the effect of chemicals on environment.In addition, it is simple and convenient,less expensive and efficient. Therefore, this method can be popularized for victim Michelia alba in parks, residetal gardens, campus etc.. |
