[目的]2010年在贵州首次发现检疫性害虫稻水象甲(Lissorhoptrus oryzophilus Kusche1),为了快速筛选出高效、低毒化学药剂,为贵州省稻水象甲成虫化学防治提供依据,采集田间稻水象甲成虫进行室内药剂生测筛选试验。[结果]48%毒死蜱EC对稻水象甲成虫防效最好,药后1 d各剂量处理防效在77%以上,药后3 d各剂量处理防效均达100%;其次为40%氯虫苯甲酰胺.噻虫嗪WG,药后1 d各剂量处理防效在72%以上,药后3 d各剂量处理防效在87%以上;10%醚菊酯SC在剂量为150、180 g a.i./hm2时,对稻水象甲成虫均有较好的防治效果。[结论]以上3种药剂防治稻水象甲成虫活性高且速效性好,可作为防治稻水象甲成虫的选择药剂。
[Objective] The quarantine pest Lissorhoptrus oryzophilus Kusche1 was first detected in Guizhou in 2010. In order to rapidly screen out high-efficient and low-toxic chemical agents, provide the basis for chemical control of adult rice waterfowl in Guizhou Province, Elephant adults for indoor pharmacy screening test. [Result] EC of 48% chlorpyrifos had the best control effect on A. asiatica, and the control effect of each dose on the 1st day after treatment was over 77%. The control effect of each dose on the 3rd day after treatment was 100%, followed by 40% Thiamethoxam WG, the control effect of each dose on the 1st day after the treatment was over 72%, the anti-efficacy of each dose on the 3rd day after the treatment was above 87%; 10% etofenproate SC at a dosage of 150, 180 g ai / hm2, have a good control effect on the waterfowl adults. [Conclusion] The above three kinds of agents had the high activity and good quick-effect to control the adults of Asiatic waterfowl.
