摘要

对采自尼日利亚南部城市阿贝奥库塔冈比亚按蚊复合体Anopheles gambiae complex的形态特征进行了研究.依据2005年8月至2006年7月灯诱捕获的364个冈比亚按蚊复合体标本,分别对它们的触角、翅、喙、前足、中足和后足6个部位的长度进行了测量,对月平均值进行回归分析,同时利用差异系数(co-efficient of difference,CD)进行近缘分析.分析显示,各特征的长度平均值雨季大于旱季,但是回归分析表明长度变化与季节不显著相关(P>0.05).差异系数分析结果表明,仅触角长度和翅长显示此复合体为两个不同的种群(CD>1.28),而其他特征值表明为同一种群.因此,该研究结果提示触角长度及翅长对冈比亚按蚊复合体近缘种的区分有重要参考价值.%Morphometric analysis of Anopheles gambiae complex Was carried out in Abeokuta metropolis.Six characters including the antennal length,wing length,pmboscis length,fore leg length,mid leg length and hind leg length,were measured in 364 individual samples of Anopheles gambiae complex collected between August 2005 and July 2006 using light traps.The monthly mean length of each character was subject to regression analysis while co-efficient of difierence (CD) was used to determine the presence of sibling species.The results revealed that the mean length in each character was higher for the wet season population as compared with the dry season population.However,the regression analysis showed that the variation was not season specific(P>0.05).Only the antennal length and wing length indicated two distinct populations when subjected to co-efficient of difierenee(CD>1.28),while other characters indicated one population.The results therefore suggest that the antennal length and wing length may be of significant value in sorting siblings of A.gambiae complex in the study area.
