In Guinea Bissau, West Africa, the shrub Hyptis suaveolens Poit. (Lamiaceae) and smoke of the bark of the tree Daniellia oliveri Rolfe (Caesalpiniaceae) traditionally are used to reduce numbers of mosquitoes indoors at night. We recorded the numbers of mosquitoes in the bedrooms of 30 households in a rural village, Mandinka-Rá in central Guinea Bissau. Each household was provided with bed nets and allocated randomly to 1 of 6 treatments as follows: (1) lambda-cyhalothrin-treated bed nets (10 mg/m2), (2) permethrin-treated bed nets (500 mg/m2), (3) burning of H. suaveolens, (4) burning of the bark of D. oliveri, (5) fresh H. suaveolens, and (6) control group using untreated bed nets and no plant products. In treatment groups 1-4, the mean number of mosquitoes was significantly less than the mean of the control. These results indicated that the use of burning H. suaveolens or D. oliveri indoors at night repelled endophagic mosquitoes and may contribute significantly to reducing the prevalence of diseases caused by pathogens transmitted by house-frequenting, nocturnally blood-feeding arthropods.
在西非的几内亚比绍，灌木香蜂草（唇形科）和奥利弗猴面包树（豆科）树皮的烟熏传统上被用于减少夜间室内的蚊子数量。我们在几内亚比绍中部一个名为曼丁卡拉的乡村记录了30户家庭卧室中的蚊子数量。每户家庭都配备了蚊帐，并被随机分配到以下6种处理方式中的一种：（1）氯氟氰菊酯处理过的蚊帐（10毫克/平方米），（2）氯菊酯处理过的蚊帐（500毫克/平方米），（3）燃烧香蜂草，（4）燃烧奥利弗猴面包树的树皮，（5）新鲜的香蜂草，（6）使用未处理蚊帐且不使用植物制品的对照组。在处理组1至4中，蚊子的平均数量显著低于对照组的平均值。这些结果表明，夜间在室内燃烧香蜂草或奥利弗猴面包树的树皮可以驱赶内食性蚊子，并且可能对降低由常在家中夜间吸血的节肢动物传播的病原体所引起疾病的流行率有显著贡献。
