侧柏毒蛾幼虫酯酶对马桑毒素及4种杀虫剂的应激性反应

在比较马桑毒素及４种杀虫剂对虫体内酯酶活力影响的基础上，分析了酯酶应激性反应的异同性。结果表明，马桑毒素Ｂ及４种药剂处理后试虫酯酶相对活力发生了显著变化。其酯酶基因的表达有３种类型，即稳定型、应激型和可抑型。同工酶谱分布频率、相似系数Ｒｉｊ、聚类分析及基因表达率分析结果表明，马桑毒素Ｂ与其它４种药剂处理间的相关性较小，但处理１２ｈ后马桑毒素Ｂ与捕杀特的Ｒｉｊ值为０．８７６４，即由马桑毒素Ｂ所引起的

Comparing Activate Reaction of Larva Esterase Isozyme of Parocneria Furva Caused by Cariaria Lactone and 4 Insecticides

Comparing influence of esterases activity caused by Cariaria Lactone B(CLB) and 4 insecticities, the difference in activate reaction of esterase was studied and analyzed.The results showed that the relative activity of esterase chang,d obviously.There are three gene expression types of esterase isozyme-stable, such as activate reaction and restrainable types.The research indicated feeble relativity existing in CLB and 4 insecticides through appearing frequency of esterase isozyme, similar coeffident R_ij cluster analysis and expressive frequency of gene.And after 12 h,R_ij=0.8764 of CLB and Pusete, that is to say,gene expression standard and biochemistry reaction type caused by CLB resembled that of Pusete; CLB could cause activate reaction of esterase isozyme firstly and later produced restrained activity when it intruded upon insect-body.
