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。

Vg could be detected in haemolmph of the water—fed female at 48h after eclosion, too.

用10％的蜂蜜和清水分别饲喂两组成虫(简称"蜜组"和"水组")，以研究成虫期的营养对Vg发生和卵巢发育的影响，结果显示，成虫期营养对于Vg的启动合成并不起关键的决定性作用，两组成虫均可以在羽化的48小时检测到Vg，且水组中的血淋巴水平并不低于蜜组对照，但绝大多数水组个体的卵巢发育停留在卵黄沉积的某一时期，此时在血淋巴中也检测不到，只有约20％的饲水个体卵巢可以发育成熟，出少量卵；用高剂量的ZR515于羽化当日点滴处理饲水个体，可以使所有接受处理的饲水个体的卵巢发育成熟，但是产卵〓依旧低于对照组的，不能恢复正常；这说明成虫期营养对卵巢中全体卵母细胞的成熟是必需的，其作用的产生是通过内分泌系统途径实现的。

每对引物均获得清晰的扩增图谱，共检出222个清晰可辨的不同扩增片段，其中多态位点189个，占85.1%；UPGMA和NJ聚类分析图显示，来自空间诱变组的M5单独聚类，而其它58个个体聚为另一类，其他太空诱变组与地面对照组的个体交叉聚类，地面对照和太空诱变组遗传差异不明显。

The results are as follow:(1) During the IR, heart rate, arterial blood pressure and myocardial oxygen consumption are decreased progressively. The epicardial electrographic ST-segment is elevated significantly during ischemia (P＜0.001) and recovers to baseline during reperfusion.
