在斯里兰卡,浅色按蚊(Anopheles subpic-tus)是最主要的内栖性蚊。随着森林砍伐和灌溉面积扩大,这种蚊的密度也相应增加。本项研究目的在于更好地认识浅色按蚊在斯里兰卡疟疾传播中的作用。实验地点位于斯里兰卡东北省新的水稻灌溉区,在1989年和1990年的4～6月(季风间期晚期到旱季早期)和1989年11～12月(东北季风期)进行了三次取样调查。6:30～9:00am,两人一组每屋捕蚊15min,每次调
Anopheles subpic-tus is the most dominant mosquito in Sri Lanka. As deforestation and irrigated areas expand, the density of such mosquitoes has also increased. The purpose of this study is to better understand the role of Anopheles pandemic in the spread of malaria in Sri Lanka. The experimental site was located in a new rice paddy area in the northeastern province of Sri Lanka. Three sampling surveys were carried out between April and June 1989 (late monsoon period to early dry season) and from November to December 1989 (northeast monsoon period) in 1989 and 1990. 6: 30 ~ 9: 00am, two groups of mosquitoes per house 15min, each transfer
