albopictus has expanded towards the border with Costa Rica since it was first reported in Panama City in 2002. aegypti has been widely distributed across Panama since its introduction in the 17th to 18th century, while Ae. The invasive spread of both species means they now coexist across much of their widespread geographical range, where they compete for space and resources. albopictus from Asia, these mosquitoes have converged on a similar ecology, ovipositing in man-made water containers and feeding on human blood. ĭespite having different biogeographical origins, with Ae. Both mosquitoes are suspected vectors of emergent chikungunya (CHIKV) and Zika (ZIKV) viruses within the Americas, yet their role in the transmission cycle of local/regional epidemics remains poorly understood. 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.Īedes aegypti and Aedes albopictus mosquitoes are aggressive invaders of anthropogenic environments capable of spreading dengue virus (DENV) with high efficiency, and can trigger epidemics even at low population density.
Garages trading used tires along highways should be targeted for the surveillance and control of Aedes-mosquitoes and the diseases they transmit. Identification of mosquito eggs by mass spectrometry depicted similar occurrence patterns for both Aedes species as that obtained with traditional rearing methods.
albopictus is associated with a decrease in road density by a log-odds of 0.36 (0.09 ± 0.63 P = 0.008). aegypti is associated with an increase in road density by a log-odds of 0.44 (0.73 ± 0.16 P = 0.002), while the presence of Ae. However, generalized linear models revealed that the presence of Ae. Resultsīoth Aedes species had a high infestation rate in garages trading used tires along the highways, providing a conduit for rapid dispersal across Panama. 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. 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. 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. The 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.
