| 中文摘要: |
| 本文调查了蓝莓园蓟马的发生动态，并选取新型及常用针对蓟马的8种杀虫剂，采用常规喷雾法比较了不同药剂、不同稀释倍数的田间药效，结果表明，①蓟马危害蓝莓主要集中在6月中旬至8月中旬，期间出现两次活动高峰，分别为6月中旬、7月中旬。②20%呋虫胺可溶性粒剂及5%啶虫脒乳油在各供试浓度下，药后1、3和7d防治效果均在60.48%以上，因此，呋虫胺与啶虫脒是防治蓟马的首选药剂，其余6种药剂对蓝莓上蓟马亦具有一定的防治效果，但选择时需要合理选用浓度及综合考虑其速效性与持效性。 |

| This study investigated the population dynamics of thrips on blueberry the pand compared field efficacy of eight pesticides against blueberry thrips by using foliar spraying methods. The results showed that blueberry thrips harm stage in mid-june to mid-august, peak appears twice during the activity, respectively in mid-june and mid-july; The control effect of 20% dinotefuran SG and 5% acetamiprid EC was above 60.48% at 1, 3 and 7 days after spraying pesticides, therefore, 20% dinotefuran SG and 5% acetamiprid EC are the first choice for controlling of blueberry thrips, the other six kinds of pesticides against blueberry aphids also to have certain control effect, but when the choice needs to select appropriate concentration and considering its readily availability and effectiveness. |
