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.

The biological safety of Bacillus thuringiensis Strain YJ-2000 which acted the low toxicity to Bombyx mori newly hatched larvae and marked insecticidal activity to other lepidopterous insects was evaluated compared with other two Bt strains,i.e.

YJ 2 0 0 0菌株除导致 1龄幼虫历期延长 11 1%、取食量减少 0～ 6 0 0 %及体重降低 5 2 3%～ 6 2 5 %外，对 2龄及其以后各龄幼虫的存活率、发育历期、取食量、眠蚕体重、化蛹率、蛹期、全茧量、蛹重、茧层量、羽化率和产卵量等均无显著影响。

Subclones of the hybrid 741 took on a high insect-resistant identity to the larvae of leaf pests such as Clostera anachoreta Fabricius, Lymantria dispar Linnacus, Hyphantria cunea Drury ect., and the mean death rate of the grubs were all above the 85%, furthermore, the grubs' growth which survived could be restrained and the growth rate was reduced so that they couldn't tie cocoons as the usual.

项目简介：转双抗虫基因741杨是将部分改造BtCryIAc 基因与慈菇蛋白酶抑制剂基因，通过农杆菌介导法转化了优良白杨杂种741杨，并获得了一批具有高抗虫性无性系，对舞毒蛾和杨扇舟蛾，美国白蛾等鳞翅目幼虫死亡率达85%以上，并能抑制存活幼虫的发育，使其不能正常化蛹。
