| 摘 要： | 马桑种子提取物对黑肩毛胸榆叶甲成虫及幼虫具有明显的拒食作用，其拒食中浓度（ＡＤＣ（５０））分别为０．０４３６ｋｇ籽／Ｌ、０．０４０５ｋｇ籽／Ｌ。并能明显地改变雌成虫的生殖行为，极大地缩短雌成虫的寿命，降低其产卵量（在０．０４３６ｋｇ籽／Ｌ处理条件下较对照下降２５．９８％）。研究结果还表明，马桑籽提取物对该虫的卵有杀伤作用，其致死中浓度（ＬＣ（５０））为０．１１７１ｋｇ籽／Ｌ。

| Abstract: | The seed extract of Coriaria sinica Maxim showed a distinct antifeedant effect on adult and larval of Pyrrhalta maculicollis.The median antifeedant concentration(AFC(50)) for adult and larval P.maculicollis are 0. 0436kg(weight of the seed, the same below)/L and 0.0405kg/L respectively.The extract also showed an effect of changing the repropductive behaviour of the female adult, and of decreasing its life span and the amount of spawned eggs(decreased by 25.98% under the concentration of 0.0436kg/L compared with the control).The extract finally showed a poisoning effect on the eggs,and the median lethal concentration (LC(50)) is 0.117kg/L. |
