１９９６年６月至１０月，在陕西省汉中盆地对锐劲特（苯基吡唑类新型杀虫剂）进行了笼罩和田间实验。目的在于弄清该杀虫剂对稻蝗的作用方式及防治价值。结果如下：１）低剂量的锐劲特（４ ｇ／ｈａ和８ ｇ／ｈａ活性物质）对稻蝗有很强的触杀和胃毒作用。触杀击倒的作用较胃毒的作用迅速；２）锐劲特对稻蝗的控制作用长达３周以上，明显长于通用杀虫剂；３）两种剂量的锐劲特作用于稻蝗时，其区别只表现在施药后稻蝗存活时间的长短，在控制效果上无明显差异；４）与空白对照田的产量相比，施用锐劲特后可挽回１２％的稻谷损失。
From June to October 1996, the fenfloxacin (phenylpyrazole new insecticide) was shrouded and field experiments in the Hanzhong Basin, Shaanxi Province. The purpose is to clarify the insecticide on the role of rice locusts and prevention and treatment. The results are as follows: 1) Low doses of fipronil (4 g / ha and 8 g / ha active) have strong contact and stomach toxicity to rice locusts. The effect of contact and knockdown is more rapid than that of stomach poison; 2) the control effect of Regent on rice locust is more than 3 weeks, obviously longer than that of common insecticide; 3) When the two doses of fipronil act on the rice locust , The difference is only manifested in the survival time of rice grasshopper after application, no significant difference in the control effect; 4) Compared with the blank control field production, the application of fipronil can save 12% of the loss of rice.
