采用夹毒叶片法比较丁烯氟虫腈与氟虫腈对东亚飞蝗蜕皮后2d的3龄若虫的毒力。结果表明,丁烯氟虫腈与氟虫腈对东亚飞蝗若虫的毒力相当。比较两者LD50、LD90,丁烯氟虫腈分别为52.76μg/g和548.03μg/g,而氟虫腈分别为38.51μg/g和216.70μg/g,亦可以看出氟虫腈对东亚飞蝗的活性要高于丁烯氟虫腈。
The toxicity of buprenorphine and fipronil to 3rd-instar nymphs of 2-day-old migratory molting of Locusta migratoria manilensis was compared by sandwich leaf method. The results showed that the buprenorphine fipronil and fipronil to East Asian locust nymph toxicity. The results showed that fipronil exerted a good effect on East Asian flying when compared with the control (LD50, LD90, butylene-fipronil of 52.76μg / g and 548.03μg / g respectively) and fipronil of 38.51μg / g and 216.70μg / g Locust activity is higher than that of butene fipronil.
