研究背景入侵性疾病媒介埃及伊蚊和白纹伊蚊的远距离传播已将节肢动物携带的病毒引入新的地理区域，造成重大的医疗和经济负担。废旧轮胎行业是伊蚊传播的有效途径，但缺乏研究来确定伊蚊的发生和影响其分布沿着当地交通网络的因素。为了评估巴拿马主要交通网络沿着的虫害，我们记录了所有现有的在高速公路上交易旧轮胎的车库，并调查了Ae的子集。埃及伊蚊和埃及伊蚊。白纹伊蚊我们还评估了一种质谱方法的能力，通过比较我们的研究结果的基础上，传统的幼虫surveillance.ResultsBoth伊蚊种蚊卵分类有很高的侵扰率在车库交易二手轮胎沿着的高速公路，提供了一个渠道，在巴拿马迅速扩散。然而，广义线性模型显示，Ae的存在。埃及伊蚊与道路密度增加相关，对数几率为0.44（0.730.16; P=0.002），而埃及伊蚊的存在。白纹伊蚊与道路密度降低相关，对数比值为0.36（0.09 +/- 0.63; P=0.008）。鉴定蚊子卵的质谱描绘了类似的发生模式，为两种伊蚊与传统的饲养methods.Conclusions车库交易二手轮胎沿着高速公路应有针对性的监测和控制伊蚊，蚊子和他们传播的疾病。使用质谱法鉴定蚊卵可以快速评估伊蚊的存在，与传统的病媒监测相比，具有时间和成本优势;这对疾病风险评估非常重要。
BackgroundThe long-distance dispersal of the invasive disease vectors Aedes aegypti and Aedes albopictus has introduced arthropod-borne viruses into new geographical regions, causing a significant medical and economic burden. The used-tire industry is an effective means of Aedes dispersal, yet studies to determine Aedes occurrence and the factors influencing their distribution along local transport networks are lacking. To assess infestation along the primary transport network of Panama we documented all existing garages that trade used tires on the highway and surveyed a subset for Ae. aegypti and Ae. albopictus. We also assess the ability of a mass spectrometry approach to classify mosquito eggs by comparing our findings to those based on traditional larval surveillance.ResultsBoth Aedes species had a high infestation rate in garages trading used tires along the highways, providing a conduit for rapid dispersal across Panama. However, generalized linear models revealed that the presence of Ae. aegypti is associated with an increase in road density by a log-odds of 0.44 (0.730.16; P=0.002), while the presence of Ae. albopictus is associated with a decrease in road density by a log-odds of 0.36 (0.09 +/- 0.63; P=0.008). Identification of mosquito eggs by mass spectrometry depicted similar occurrence patterns for both Aedes species as that obtained with traditional rearing methods.Conclusions Garages trading used tires along highways should be targeted for the surveillance and control of Aedes-mosquitoes and the diseases they transmit. The identification of mosquito eggs using mass spectrometry allows for the rapid evaluation of Aedes presence, affording time and cost advantages over traditional vector surveillance; this is of importance for disease risk assessment.
