| 摘 要： | 为了确定石菖蒲(Acorus gramineus Soland)提取物对褐飞虱Nilaparvata lugens St1的活性及使用浓度,研究了石菖蒲提取物对褐飞虱的触杀毒力,30%石菖蒲乳油及30%石菖蒲扑虱灵混配乳油对褐飞虱的室内盆栽试验及大田试验防治效果。结果表明,石菖蒲提取物对褐飞虱3龄若虫及长翅型雌成虫处理48h后的LD50分别为0.64和0.95μg/头。室内盆栽试验表明:30%石菖蒲乳油30倍、30%石菖蒲扑虱灵混配乳油50倍施药3d后对褐飞虱3龄若虫的校正死亡率分别为85.56%和96.67%。30%石菖蒲乳油20倍、30%石菖蒲扑虱灵混配乳油300倍,施药7d后,对褐飞虱的田间防治效果分别为78.46%和79.76%。 |

| Abstract: | Contact toxicity and control effect of Acorus gramineus Soland extract,A.gramineus extract 30% EC and buprofeizin 30% EC,against Nilaparvata lugens St1 were studied.The results show that after being treated with A.gramineus extract for 48 hours,the LD50 of 3rd instar and macropterous females was 0.64 μg/instar and 0.95 μg/adult.In an indoor potted test,a 30 times dose of A.gramineus extract 30% EC and a 50 times dose of dosage buprofeizin 30% EC showed significant control effect on the 3rd instar,achieving mortalities of 85.56% and 96.67% respectively three days after treatment.A field trial showed that the control effect of a 20 times dosage of A.gramineus extract 30% EC and a 300 times dosage of extract-buprofeizin 30% EC were 78.46% and 79.76% respectively after seven days. |
