摘要
茶小绿叶蝉Empoasca onukii Matsuda是茶园最难防治的主要害虫之一。为研究其微波防控技术参数,在室内分别以0、100、200、400、500、600和800W微波处理茶小绿叶蝉成虫1min,研究其对茶小绿叶蝉的杀死数量;另外以0、100、200、300、400、500和600 W微波分别辐射5、7、9、11、13、15、17min,记录茶小绿叶蝉成虫即时死亡头数。结果表明,不同功率微波辐射茶小绿叶蝉1min,对其16d的死亡数量影响不显著;其中,600W在第7d累计死亡率为64.4%。600W微波辐射茶小绿叶蝉7～17min,其即时死亡数量显著高于其他功率微波辐射的处理;600W微波辐射13、15和17min,即时死亡率分别为61.1%、83.3%和87.8%。因此,拟推荐微波功率600W、微波辐射时间13min的组合,作为防治茶小绿叶蝉的生产应用参考指标。
The leafhopper Empoasca onukii Matsuda is a difficult pest to control.As a result,high dosages of insecticide are often used in tea plantations.To search for an effective alternative,applying microwave to reduce the population was investigated.The mortality rate of E.onukii adults by exposing the insects to microwave power at 0,100,200,400,500,600,or 800 W for 1 min was determined in the laboratory.Meanwhile,the pests were also irradiated at microwave of 0,100,200,300,400,500,and 600 W for 5,7,9,11,13,15,and 17 min for an instant kill.Under the 1 min treatments,no significant differences were found on the insect mortalities in 16 d.The cumulated mortality was 64.4%on day 7 when 600 W microwave was applied.On the other hand,the same microwave power produced significant more instant deaths on E.onukii treated for 7-17 min than any other power levels.It killed the pests at the rates of 61.1%,83.3%,and 87.8%in 13,15,and 17min,respectively.Thus,an application of 600 W microwave for 13 min might be practical after further optimization on the treatment for a pest control measure on E.onukii.
