摘  要：
采用海绵水盘法研究了苹果Malus pumila Mill.、接骨木Sambucus illiamsii Hance、苦楝Melia azedarach L.、火炬树Rhus typhina L.对二斑叶螨Tetranychus urticae Koch生长发育和繁殖的影响,并分别采用凯氏定氮法、索氏提取法、蒽酮比色法、Folin-Denis比色法测定了植物叶片全氮含量、粗脂肪含量、可溶性糖含量、单宁含量。结果发现:苹果和接骨木叶片的全氮(分别为2.98%和4.00%)和可溶性糖(分别为19.92%和12.81%)含量较高,有利于二斑叶螨生长发育和繁殖。而火炬树叶片的全氮量(2.60%)、可溶性糖含量(4.98%)最低,单宁含量(11.45%)最高,对二斑叶螨具有较强的抗性。单宁可能是植物抗螨性形成过程中起主要作用的次生物质。

摘  要：
Effects of Malus pumila Mill., Sambucus williamsii Hance, Melia azedarac L. and Rhus typhina L. on the development and fecundity of Tetranychus urticae Koch were investigated by means of leaf disk rearing method. Kjeldahl method, Soxhlet extraction method, Anthrone colorimetry, and Folin-Denis colorimetry were also applied to measure the contents of nitrogen, crude fat, soluble sugar and tannin, respectively. The results showed that M. pumila and S. williamsii with high content of nitrogen (2.98% and 4.00%, respectively) and soluble sugar (19.92% and 12.81%, respectively) were suitable for the development and fecundity of T. urticae. R. typhina with the lowest content of nitrogen and soluble sugar and the highest content of tannin (11.45%), however, was baneful to T. urticae. Therefore it can be concluded that tannin, as the secondary compound of plants, may play important role in resistance of plants to mites.
