苦参碱(Matrine)是由苦参的根、茎、叶和果实提取制成,是一种新型的生物防治制剂.试验设1%苦参碱可溶性液剂和4.5%氯氰菊酯乳油2个试验组,每试验组分3个剂量:1%苦参碱225、300和450 mL/hm~2;4.5%氯氰菊酯450、600和750 mL/hm~2,共6个处理.结果表明:3个剂量的1%苦参碱对防治荒漠草原蝗虫均具有一定的防治效果.450 mL/hm~2的1%苦参碱与常用农药4.5%氯氰菊酯450和600 mL/hm~2 2个剂量的防治效果无差异,因苦参碱为植物源杀虫剂,在防治荒漠草原蝗虫时可选择使用,以保护生态环境,减少污染.

Matrine, a new type of biological control agent extracted from the root, stem, leaf and fruit of Sophora flavescens, was used to study its effect on the control of grasshopper in desert grassland. Two experimental groups were designed with 1% of matrine extract and 4.5% cypermethrin and totally 6 treatments (1% matrine 225 mL/hm~2, 300 mL/hm~2 and 450 mL/hm~2; 4.5% cypermethrin 450 mL/hm~2, 600 mL/hm~2 and 750 mL/hm~2) were used. The results showed that 3 concentrations of 1% matrine showed control effect. The treatment of 1% matrine at dose of 450 mL/hm~2 showed no difference with the treatment of 4.5% cypermethrin at doses of 450 mL/hm~2 and 600 mL/hm2. So, the matrine should be the top-priority for the grasshopper control because of its environmental safety.
