摘要
采用浸渍叶碟法研究天葵块根提取物对菜青虫、小菜蛾生长发育的影响.结果表明,天葵块根提取物对菜青虫、小菜蛾具有明显的生长发育抑制作用,800mg/L对菜青虫、小菜蛾的生长发育抑制率分别为67.18%,68.31%.该提取物对菜青虫、小菜蛾生长发育抑制IC_(50)分别为389mg/L,251mg/L,对试虫的体重增加也有显著影响,处理组的平均体重增加值显著低于对照.
In this passage, it is reported that the root of Semiaquilegia adoxoides exhibits a higher level of growth disrupting effects on the larvae of Plutella xylostella L and Pieris rapae L. by dipping leaves methods. The results showed that The inhibit rate of development of Pieris rapae Land Plutella xylostella L. is 67.19% and 68. 31%, respectively, when the larva were fed with cabbage leaves dipped with 800 mg/L abstract. The IC50 value of the Semiaquilegia adoxoides abstract against the tested larvae of Pieris rapae Land Plutella xylostella L. were 389mg/L and 251mg/L, respectively, The root abstract of Semiaquilegia adoxoides also had notable influence on the body weight increase of insect tested. The increased amount of body weight of the larvae tested were lower significantly than the control.
