| 摘要: |
| 钝绥螨属拉戈群的不少种类是叶螨、跗线螨和瘿螨的重要天敌。分清种类是利用它们的前提。拉戈群中的种间形态差异不大,鉴定时容易混淆。本试验用采自江苏和四川茶树的两种钝绥螨进行杂交和形态、生物学比较。研究结果表明,这两个种存在着明显的生殖隔离。二者胸板后缘形态差异显著,前者为江原钝绥螨(Amblyseius eharai Amitai et Swirski);后者为草栖钝绥螨[A.herbicolus(Chant)],德氏钝绥螨(A.deleoni Muma et Denmark)是它的同物异名。比较二者的发育速度、产卵量及分布地区,可看出江原钝绥螨更有利用价值。 |

| Abstract: |
| Some species of Largoensis group,Genus Amblyseius are important natural enemies of some mites for Tetranychidae, Eriophidae and Tarsonemidae.But diffrences of mophology among those species are not obvious.It is easy to be confused amorig those species. Hybridization and comparative studies of morphology and biology between two similar species of largoensis group,genus Amblyseius were conducted.Speci- mens were collected from tea trees of Jiangsu and Sichuan Provinces. Results indicated that:(1)These two spe... |
