河北省白洋淀蝗区防治蝗虫替代药剂研究

河北省白洋淀是华北地区最大的淡水湖,也是全国重点湖泊蝗区之一,该地区的蝗虫以东亚飞蝗为主。目前对于该地区东亚飞蝗的治理仍以采用马拉硫磷、氰戊菊酯等有机磷类和菊酯类为主。这些药剂的用量较大,长期使用造成了严重的环境污染、害虫抗药性增加等问题。本研究自行研制了防蝗替代药剂5%吡虫啉OL,并进行了田间试验,明确其田间用量和防治效果。结果表明：与其他药剂相比,该药剂更适用于该地区控制蝗虫为害。

Study on Substituted Insecticides on Controlling Locusta migratoria manilensis in Baiyangdian Lake of Hebei Province

Baiyangdian Lake was the largest freshwater lake in North China,and it was also one of the major area damaged by L.migratoria.Malathion and fenvalerate were commonly used to control it.The environment was polluted seriously,and the resistance of locusts to insecticides was increasing quickly because of the abusing of these pesticides.5% imidacloprid OL was developed by ourselves,and its dosage and field control efficiency were studied.The results showed that it was more suitable for controlling L.migratoria.
