The ecology of Culicoides paraensis was studied with human bait collections at an agricultural research station near Belém and within 2 neighborhoods of Belém, Brazil, from 1977 to 1978. From collections conducted along transects that were centered on a house, we found most dense populations of host-seeking midges within and near the house. Host-seeking activity was least in areas fully exposed to sunlight compared to the levels of activity indoors and in shaded areas outside. Numbers of flies biting under shade trees and within the house increased during intervals of rain; concomitantly the levels of activity decreased in open areas. Seasonal population densities correlated with the pattern of rainfall, with a 2-month lag due to the long maturation time of immature C. paraensis. The effects of temperature and humidity on host-seeking activity are discussed.
1977年至1978年期间,在巴西贝伦附近的一个农业研究站以及贝伦的两个社区内,通过人体诱饵诱捕的方式对副库蠓的生态学进行了研究。从以一所房屋为中心的样带采集的数据来看,我们发现寻找宿主的蠓虫在房屋内部及其附近的种群密度最高。与室内和室外阴凉处的活动水平相比,在完全暴露于阳光下的区域,寻找宿主的活动最少。在树荫下和房屋内叮咬的蠓虫数量在降雨期间会增加;与此同时,空旷区域的活动水平会下降。季节性种群密度与降雨模式相关,由于未成熟的副库蠓成熟时间较长,存在两个月的滞后。文中还讨论了温度和湿度对寻找宿主活动的影响。
