CHEMOSYSTEMATIC GEOGRAPHIC VARIATION IN AEDES ALBOPICTUS

这项建议有三个广泛的长期目标：1)确定 根据选定的表型，世界各地地理位置的关联性 白纹伊蚊种群(双翅目：蚊科)，2 为以后的扩展研究提供研究基础 完成本研究，以及3)提供研究 关注健康的本科生心得体会 职业。白纹伊蚊，一种有效的媒介 病毒性疾病，最近已被引入北美。 这项建议的近期研究目标是：1) 毛细管气相色谱电子能谱的化学表征 冲击质谱学主要成分(大于0.5%的化合物 相对丰度)成年男性角质层碳氢化合物 和雌性Ae.白纹伊蚊；2)定量表征， 利用毛细管气相色谱，角质层碳氢化合物 Ae.白纹伊蚊的个体和地理分布 变种。角质层碳氢化合物将从单一 标本。角质层碳氢化合物峰，利用毛细管气体 层析分析，从至少14个样品中获得 来自亚洲和北美的人口将被用作 用于地理信息多元统计分析的字符集 变种。

This proposal has three broad long-term objectives: 1) to determine relatedness, based on selected phenotypes, of world-wide geographic populations of Aedes albopictus (Skuse) (Diptera: Culicidae), 2) to provide a research base for extended studies after the completion of the present research, and 3) to provide research experiences for undergraduate students interested in health professions. Aedes albopictus, an efficient vector of several viral diseases, has recently been introduced into North America. The immediate-research objectives of this proposal are to: 1) chemically characterize by capillary gas chromatography electron impact mass spectrometry the major (compounds greater than 0.5% relative abundance) cuticular hydrocarbon components of adult male and female Ae. albopictus, and 2) quantitatively characterize, using capillary gas chromatography, the cuticular hydrocarbon profiles of Ae. albopictus in terms of individual and geographic variation. Cuticular hydrocarbons will be extracted from single specimens. Cuticular hydrocarbon peaks, utilizing capillary gas chromatography analysis, obtained from specimens of at least 14 populations from Asia and North America will be utilized as character sets for multivariate statistical analysis of geographic variation.
