摘要
为了解天牛取食对象的改变与虫体酯酶变化的关系，采用垂直板聚丙烯酰胺凝胶电泳及酯酶染色的方法，对取食不同树种的桑天牛幼虫酯酶同功酶进行了研究。ＰＡＧＥ分析表明，取食７个树种的桑天牛幼虫均有３条相同的酯酶同功酶谱带，其中取食毛白杨和苹果时则多出１条迁移率为０．６７的谱带。
In learning the relationship between the host tree species and the esterase in Apriona germarii fed with,the PAGE was used to study the effect of different tree species on esterase isozymes in larvae of the insect.The results showed that all the larvae fed with 7 different tree species shared 3 identical zymogram bands,but those fed with Populus tomentosa and apple leaves had one band more with migration rate 0 61.
