摘要
通过对江西不同桔园 1997年至 1998年螨类自然种群消长动态的调查结果表明 :不同柑桔品种园中螨类组成有所不同 ,消长规律年与年之间有所差异 ,特别是种群数量方面。不同柑桔品种之间的柑桔全爪螨发生时间和数量不同 ,这也许是不同柑桔品种之间对柑桔全爪螨的抗性不同所致 ,这同时导致了不同柑桔品种之间长须螨和植绥螨发生有所不同。
Population dynamics of mites from varieties of citrus orchards in Jiangxi were investigated .The results showed the species of mites form different vatieties.Population dynamics of mites are not the same from year to year,especially the numbers of mites.The numbers and population dynamics of the red mite Panonychus citri McG.are often different in varieties of citrus trees.It may be the reason that the resistance of varieties of citrus tree to P.citri are different.In the same time,it may make the population dynamics of stigmaeid mites and photoseiid mites are different.
