摘　　要：通过筛选分离 ,获得了腺毛翠雀花 (Delphimium grandiflorum var.glandulosum)、大伞花楼梯草 (Elatostema umbellatum BL .var.majus Maxim)、毛莨 (Ranunculus japonica Thunb)、兔儿伞 (Syneilesisaconitif olia (Bge.) Maxim)等天然植物的提取液。以蟋蟀、蚱蜢、粘虫、毛虫为试虫 ,测定了各种提取液对试虫的毒杀活性 ,发现这几种植物均具有良好的杀虫活性。其中腺毛翠雀花、大伞花楼梯草在 30 min内对蟋蟀、蚱蜢 (体长≤ 3cm)杀死率达 90 %以上 。The 4 extracts are obtained using screening separation from Delphinium grandiflorum var. glandulosum [Ranunculaceae],Elatostema umbellatum BL. var. majus Maxim [Urticaceae], Ranunculus japonica Thunb. [Ranunculaceae] and Syneilesis aconitifolia (Bge.) Maxim [Composipae]. Crickets, grasshoppers, armyworms and caterpillars are used as experiment insects for determining the extracts insecticidal activities. The extract solutions of Delphinium grandiflorum var. glandulosum and Elatostema umbellatum BL. var. majus Maxim kill crickets and grasshoppers,whose body length is ≤3 cm,are 100% at 9 min,and 90% at 30 min respectively,but the extract solutions are saft for fishes.
