摘　　要：为筛选出用于防治茶树茶小绿叶蝉的高效低毒药剂,选择8种杀虫剂开展了田间药效试验并进行了比较。结果表明:20%呋虫胺可溶粒剂对茶树茶小绿叶蝉的防治效果最好,药后1、3、7d防效分别为72.34%、90.34%和94.99%;其次为25%丁醚脲悬浮剂和20%氟啶虫酰胺悬浮剂,药后7d防效分别为89.88%和86.06%;150g/L茚虫威乳油、0.5%甲维盐微乳剂和15%唑虫酰胺悬浮剂对茶树茶小绿叶蝉速效性和持效性均不突出;10%联苯菊酯水乳剂和240g/L虫螨腈悬浮剂虽速效性较好,但持效性较差。8种杀虫剂在试验剂量下对茶树安全。In order to screen the high-efficiency and low-toxicity agents that can be used to prevent Empoasca pirisuga Matumura,8 insecticides were selected to conduct the field efficacy test.The results showed 20%dinotefuran SG had the best control efficacy,the results were 72.34%,90.34%and 94.99%1,3 and 7 days after treatment respectively.25%diafenthiuron SC and 20%flonicamid SC had the second best control efficacy,the results were 89.88%and 86.06%7 days after treatment respectively.The rapid efficacy and persistence of 150 g/L indoxacarb EC,0.5%emamectin benzoate ME and 15%tolfenpyrad SC were not prominent.Although the 10%bifenthrin EW and 240 g/L chlorfenapyr SC had good rapid efficacy,their persistence were poor.Within the testing dosage,these eight insecticides were safe for tea trees.
