Studies were carried out in the villages of Kapkuikui and Maji-Ndege in the Loboi area of Baringo District, Kenya, to obtain baseline data on species identification of the Anopheles gambiae group, their feeding and resting behavior, and their frequencies of chromosomal inversions. This was carried out towards predicting the effect of introducing permethrin-impregnated cloths or other intervention measures. In this study, Anopheles arabiensis was identified as the only species of the An. gambiae group. This species contained 2 inversions, 2Rb and 3Ra, occurring at frequencies ranging from 55 to 60%, and from 5 to 11%, respectively. There was no evidence for nonrandom mating. Indoor- and outdoor-collected samples were significantly different in respect of inversion 3Ra in one village and in the distribution of the different sources of blood meals in both areas. In these villages, 37% of indoor-resting mosquitoes fed outside before entering houses to rest.
在肯尼亚巴林戈区洛博伊地区的卡普库伊奎村和马吉-恩德盖村开展了研究，以获取关于冈比亚按蚊种群的物种鉴定、其摄食和栖息行为以及染色体倒位频率的基线数据。开展此项研究是为了预测引入经氯菊酯处理的蚊帐或其他干预措施的效果。在本研究中，阿拉伯按蚊被鉴定为冈比亚按蚊种群的唯一物种。该物种包含2种倒位，即2Rb和3Ra，出现频率分别为55%至60%和5%至11%。没有证据表明存在非随机交配现象。在一个村庄，室内和室外采集的样本在3Ra倒位方面存在显著差异，并且在两个地区不同血餐来源的分布上也存在显著差异。在这些村庄，37%的室内栖息蚊子在进入房屋休息前在室外觅食。
