摘要
对一品红花卉烟粉虱的田间消长规律及药剂防治效果进行了调查试验。结果表明,7月中旬始见成虫,8月下旬出现第1次成虫高峰,9月上旬出现第2次成虫高峰,此后虫口逐渐下降,10月中下旬以后随着一品红移入温室,烟粉虱进而继续在温室为害;使用的药剂以阿维菌素、吡虫啉和扑虱灵对烟粉虱的防治效果较好,药后7d防效均达90%以上,在生产上这3种药剂可轮换使用。
The dynamics of B. tabaci is studied in the field of Euphorbia pulcherrima Willd in this paper. From middle tenday of July to last ten-day of October,there are two peak of Euphorbia pulcherrima Willd, population, which appears in last ten-day of August and first ten-day of September. Through comparing the effect of five pesticides on Euphorbia pulcherrima Willd in the fields,Abamecitin, Imidacloprid and Buprofezin show better control effect. The control effect on the adults and larvae of B. tabaci was over 90% after seven days. The controlling of B. tabaci can replace with use this three pesticides.
