摘　　要：本文以花生地下害虫花生新黑地珠蚧为研究对象,对其田间危害及虫体发育情况进行了调查,并利用分子生物学技术对其进行系统发育研究。田间调查结果表明,花生新黑地珠蚧在河南省一年发生一代,多发生于沙壤土,主要以珠体状的2龄若虫为害花生根部;雌雄珠体数量及大小差异均较大,单株花生上为害的雌珠体数17~78头,雄珠体数59~146头,雌雄珠体性比为1.00∶2.61,雌雄珠体直径分别为4.72~7.26 mm和1.83~2.65 mm。通过系统发育分析和传统形态学分类的综合分析表明本研究中所采集害虫为花生新黑地珠蚧,隶属于半翅目蚧总科珠蚧科。This study aims to investigate the field hazard and development of Neomargarodes gossypii,and reconstruct the phylogenetic relationship among different families.Field survey indicated that N.gossypii occurred one generation per year in Henan province which fed on the roots of peanut by its pearl shaped 2nd-instar nymph,and preferred sandy soil habitats.There were large differences on the amount and size between female and male pearl.The amount of female and male pearl per peanut was 17~78 and 59~146,respectively and the sex ratio was 1.00∶2.61.The diameters of female and male pearl were 4.72~7.26 mm and 1.83~2.65 mm,respectively.Through comprehensive analysis of phylogenetic tree and morphological classification,the samples collected in Henan peanut fields were identified as N.gossypii that belongs to Margarodidae(Hemiptera:Coccoidea).
