春季金银木蚜虫防控试验

Prevention and control forward of Semiaphis heraclei in Spring

该文研究了2种植物源药剂0.3%印楝素乳油(EC)500倍液、0.3%苦参碱水剂(AS)1000倍液,在春季日平均温度15℃和20℃时,对金银木蚜虫的防控效果。结果表明:日平均温度达到15℃时,0.3%印楝素乳油(EC)500倍药液防治金银木蚜虫效果相对较好,药效持续时间相对长。春季对金银木蚜虫防控,较好的控制了金银木蚜虫干母蚜种群数量,降低危害程度。

In this paper,effect on the prevention and control of Semiaphis heracleithe by two plant-derived pesticides 0.3%azadirachtin emulsion(EC)500 times liquid and 0.3%matrine water(AS)1000 times liquid were studied at 15℃and 20℃daily average temperature in spring.The results showed that n this paper,effect on the prevention and control of Semiaphis heracleithe by 0.3%azadirachtin emulsion(EC)500 times liquid was relatively good when the average daily temperature reached 15℃,and the efficacy lasted for a relatively long time.In the spring,effect on the prevention and control of Semiaphis heraclei moved forward the prevention and control time,which better controlled the population number of fundatrix,reduced the degree of harm.
