甘薯小象甲是国内外重要检疫性害虫，明确中国不同地区甘薯小象甲的遗传多样性可为甘薯小象甲的鉴别检疫提供依据。本文通过对中国6个地区甘薯小象甲种群rDNA ITS-1序列的遗传变异分析探讨了中国6个地区种群的入侵来源。结合世界其他地区已公布35个甘薯小象甲种群序列，经系统发育分析表明，甘薯小象甲起源于印度次大陆，在亚洲地区随甘薯的调运而自东南向西北扩展，构建的系统发育树分为印度地区分支和亚洲东部分支两...
为给小麦孢囊线虫综合治理提供一定的理论依据，通过对苏皖鲁豫接壤地区30块田的调查和分析，探讨了这些地区麦田小麦孢囊线虫的发生情况及线虫群体之间亲缘关系。结果表明，采集的30份样品中都能检测到孢囊线虫，孢囊密度为每100 g土壤1~80个。进一步对30个小麦孢囊线虫群体的rDNAITS区PCR扩增、测序，对其序列进行比较分析发现，30个分离物的核苷酸序列同源性为97.1%～100%，与已报道的中国...
