In this paper, we determined the toxicity of transgenic Betula platyphylla with Bt spider peptide gene. Larvae of Lymantria dispar were feed on leaves of transgenic Betula platyphylla with Bt spider peptide gene, The mortality, reduced ratio of weight, ecdysis index and schedule time of every instar.

本文对转Bt C肽蜘蛛杀虫肽的白桦进行杀虫性测定，对取食对照和转基因植株舞毒蛾幼虫的死亡率、体重降低率、蜕皮指数、幼虫各龄级历期等指标进行了分析，证明外源基因已经成功插入白桦基因组中，并且能够表达杀虫蛋白。

They have the same expression trend:In the 5~ instar,the expression level is lowest,which increases great with eclosion and declines a little at 5 hours after eclosion,then increases again at 7 hours and 1 day after eclosion.

它们都有一个相同的表达趋势：在5龄时，表达量较低；在羽化时，有了很大的增加；但是在羽化后5小时，MLC2的表达量有稍微的下降；随后在羽化7小时和羽化1天时，基因表达量都是增加的。

The SGC-7901GA cells and control cells SGC-7901Neo were cultured in vitro,and then were respectively injected into the endermic tissue of 6-weeks-old BALB/C node mice to create the animal models of tumor. The neoplasia and growth of tumor were observed. Use MTT method to detect the difference of growth capability of two kinds of cells in vitro.
