摘要
为了解埃及吹绵蚧在砂糖桔上的发生情况,采用5点取样法对其发生情况及特点进行了调查,并选用25%优乐得1000倍液、95%机油乳剂100倍液进行了防治试验。结果表明:高要市部分的砂糖桔果园上全年可见埃及吹绵蚧危害;25%优乐得1000倍液10 d和30 d的虫口减退率分别达87.1%和72.7%。95%机油乳剂100倍液7 d和30 d的虫口减退率分别达81.1%和42.1%,2种药剂均有较好的防治效果。
To understand the occurrence and damage and control measures of Icerya aegyptiaca on Citrus shatangju, 5 point sampling method was adopted, and 1 000 times of 25% buprofezin and 100 times of 95% petroleum spray oil was applied in the experiment. The results showed that the damage of I. aegyptiaca on C. shatangju in Gaoyao county could be observed in the whole year, and the two chemicals had better control effect, and the decreased rate of I. aegyptiaca reached 87.1% and 72.7% after 10 and 30 days of buprofezin application, respectively. Similarly, the decreased rate of I. aegyptiaca reached 81.1% and 42.1% after 7 and 30 days of petroleum spray oil respectively.
