在山东省寿光市开展利用胡瓜钝绥螨控制日光大棚甜椒上的西花蓟马的研究与应用结果显示:①利用胡瓜钝绥螨能有效控制西花蓟马的种群增长;②在甜椒的整个生长季节(270 d)中需释放2～3次胡瓜钝绥螨:苗期每次释放5～10头/株,结果期每次释放20～30头/株;③释放胡瓜钝绥螨的生防区比常规化防区减少农药使用10次;④释放胡瓜钝绥螨的生防区在释放后25 d左右,对西花蓟马种群控制效果为81.1%～86.7%,35 d左右达92.7%,55～85 d期间一直维持在91.4%～94.5%之间;常规化学防治效果分别是第25 d左右为41.1%～53.9%,35 d左右达56.9%,第55～85d期间一直维持在73.7%～74.9%。试验表明,胡瓜钝绥螨对为害甜椒上西花蓟马有良好的控制作用,明显好于常规的化学防治控制作用。
The research and application results on the control of western flower thrips on the sunlight pepper in the sunflower in Shouguang, Shandong Province showed that: (1) the use of the cucumber amblyseius Amblyseius can effectively control the population growth of the western flower thrips; (2) (Cucurbita moschatae) was released 2 or 3 times during the whole growing season (270 days): 5 ~ 10 heads per plant at seedling stage and 20 ~ 30 heads per plant in the result period; Of the biological defense zone than the conventional zone to reduce the use of pesticides 10 times; ④ release cucumber Amblyseius biological control zone 25 days after release, the control effect on the population of western flower thrips was 81.1% ~ 86.7%, about 35 d up to 92.7% , And maintained between 91.4% and 94.5% in 55-85 days. The results of conventional chemical control were 41.1% -53.9% at 25th day and 56.9% at 35th day, respectively, and kept at 73.7 during 55th-85th day % ~ 74.9%. Tests showed that cucumber Amblyseius cucumeris had good control effects on the damage of sweet pepper on the western flower thrips, which was significantly better than the conventional chemical control.
