蚊子采样效率的CDC微型光陷阱，相对于夜间叮咬的收集，在坦桑尼亚沿海的两个地点进行了室内评估。我们发现，一夜之间通过灯光陷阱（挂在使用的蚊帐旁边）捕获的按蚊总数是通过人类诱饵收集捕获的按蚊数量的1.23倍。这种关系并没有受到蚊子密度，诱捕方法的顺序，采样日期，或家庭居住者的数量的变化显着，疟疾孢子率的两倍高的蚊子捕获的光陷阱相比，夜间叮咬收集。这是由于光诱倾向于捕捉更大比例的妊娠蚊子，这也有较高的子孢子率。根据腹部阶段的子孢子率的差异表明，光阱捕获的未进食的蚊子可以更精确地定义人类叮咬活动和子孢子率，如夜间叮咬收集所见。我们的研究表明，光陷阱，结合夜间叮咬收集，可以是一个有效的和敏感的手段，用于测量人类叮咬活动和子孢子率。
The mosquito sampling efficiency of CDC miniature light-traps, relative to night-biting collections, was evaluated indoors at two sites in coastal Tanzania. We found that the total number of anophelines captured overnight by light-traps (hung beside a bednet in use) was 1.23 times the number of anophelines captured by human-bait collections. This relationship was not affected significantly by changes in the mosquito density, order of trapping method, date of sampling, or number of household occupants, Malaria sporozoite rates were twice as high among mosquitoes captured by light-trap as compared to those captured by night-biting collection. This was attributed to the tendency of light-traps to capture a larger proportion of gravid mosquitoes, which also had high sporozoite rates. The differences in sporozoites rates according to abdominal stage indicates that unfed mosquitoes captured by light-traps may define more precisely the human-biting activity and sporozoite rates as seen by night-biting collections. Our study shows that light-traps, when used in combination with night-biting collections, can be an effective and sensitive means for measuring human-biting activity and the sporozoite rate.
