【摘要】 大劣按蚊是海南省疟疾的主要传播媒介。本文应用气相色谱法,分析海南省不同地区、不同季节大劣按蚊的皮质烃类。经统计学分析,它们的成分无显著性差异。应用聚类分析法,它们的距离系数很接近。提示海南省的大劣按蚊很可能是同一种。更多还原

【Abstract】 In order to identify the members of Anopheles dims complex of Hainan Province,an analysis of relative content of cuticular saturated n-paraffins of Anopheles dirus collec- ted from different localities and in different months in Hainan Province was performed by using gas chromatography.The difference among the cuticular hydrocarbons n-pr.raffins components was atitistically insignificant.The values of stepwise cluster analysis (Q model) were very close for all the collected populations.These data suggested that there might be are species of Anopheles dims complex which was further confirmed by the similarities bet-ween blood preference,seasonal variation,and nocturnal activity.更多还原
