The invasive Asian Tiger mosquito, Aedes albopictus, is an abundant and severe pest mosquito in urban and suburban environments across much of Illinois. Its aggressive daytime biting behavior can greatly impact residents’ quality of life, and there is considerable concern for its potential to support autochthonous transmission of introduced pathogens (e.g. Zika virus). The Asian Tiger mosquito only recently became established in Champaign County, providing an opportunity to study population-level traits critical to arbovirus transmission potential near the boundary of its current geographic range. In the summer of 2018, we used adult mosquito traps and human landing collections (HLCs) to compare the seasonal abundance and human-biting rate of host-seeking Ae. albopictus among several residential yards across Champaign-Urbana . The longevity of field-collected, adult mosquitoes was also measured post-capture to generate estimates of daily survival and age structure. At all residences sampled, Ae. albopictus was observed to be the most abundant mosquito attacking humans during the daytime (~95% of specimens collected by HLC). Average Ae. albopictus landing counts in Urbana-Champaign were found to be comparable to previously reported values from locales where this species is long-established and described as very abundant.
