| 中文摘要: |
| 为筛选出用于防治棕榈蓟马的有效药剂, 采用玻璃残留处理法测定了5种药剂对蔬菜上棕榈蓟马的室内毒力, 并进行了田间药效试验。室内毒力测定结果表明, 杀虫活性最高的是乙基多杀菌素, 其48 h的LC50值为0.19 mg/L; 其次是阿维菌素、溴氰虫酰胺和啶虫脒, LC50为54.45～76.48 mg/L, 呋虫胺的毒力最低。田间试验结果表明, 6%乙基多杀菌素悬浮剂和1.8%阿维菌素乳油对棕榈蓟马药后1～14 d的防效均达90.88%以上, 明显高于其他3种药剂。6%乙基多杀菌素悬浮剂是防治棕榈蓟马的首选药剂, 推荐轮换使用1.8%阿维菌素乳油和10%溴氰虫酰胺可分散油悬浮剂。 |
| 英文摘要: |
| In order to select effective insecticides to Thrips palmi Karny, toxicity of five insecticides to T. palmi on vegetables was determined using a residue on glass exposure method, and control efficacy was investigated by field trials. Laboratory bioassay demonstrated that spinetoram had the highest toxicity among all the tested insecticides, with an LC50 value of 0.19 mg/L after 48 h, followed by abamectin, cyantraniliprole and acetamiprid, with the LC50 values ranged from 54.45 to 76.48 mg/L, and dinotefuran showed the lowest toxicity. Field trial showed that the control efficacy of 6% spinetoram SC and 1.8% abamectin EC to T. palmi was were all above 90.88% after application for 1 to 14 days, significantly higher than that of the other three pesticides. So 6% spinetoram SC is the preferred insecticide to control T. palmi, and the recommended insecticides to rotate are 1.8% abamectin EC and 10% cyantraniliprole OD. |
