摘    要:室内采用叶碟饲养的方法研究了苹果、桃、李、樱桃和杏等不同果树对山楂叶螨Tetrancychusvienensis生长发育和繁殖的影响。结果表明,在李树上山楂叶螨的发育历期短、生殖力强、存活率高,rm值大,而在樱桃和杏树上该螨的发育历期长、生殖力弱、存活率低、rm值小。寄主转换试验结果表明,当山楂叶螨由苹果转移至樱桃和杏树时,其生长发育的历期显著延长,rm值大幅度降低;而由苹果转移至桃树和李树时,其生长发育的历期虽也有所延长,但差异不显著,rm值则明显降低。表明山楂叶螨对新寄主的适应因不同寄主而异,在桃和李上经历1代后即可适应,而在杏和樱桃上经历2代后才能适应新的寄主。

关 键 词:山楂叶螨  苹果        樱桃  内禀增长率

Abstract:Hawthorn spider mite (HSM), Tetranychus viennensis Zacher, is an important and damaging pest in apple orchards worldwide and has become the most serious pest on apple in north China. The hosts of this pest are mainly fruit trees of the family Rosaceae. To assess host suitability of deciduous fruit trees in family Rosaceae, a leaf disc bioassay was employed to investigate the influence of five species of deciduous fruit trees, which included apple, peach, plum, cherry, and apricot, on the development and rep...
Keywords:hawthorn spider mite  intrinsic rate of increase  apple  apricot  cherry  peach  plum
