We exploited elevation gradients (1,500–2,400 m) ranging from plains to montane areas along the Poudre River and Big Thompson River in the northern Colorado Front Range to determine how mosquito...

The human-biting adult stage of the Rocky Mountain wood tick (Dermacentor andersoni) can cause tick paralysis in humans and domestic animals and is the primary tick vector in the intermountain west...
Understanding spatial patterns of human risk of exposure to arthropod vectors and their associated pathogens is critical for targeting limited prevention, surveillance, and control resources (e.g.,...

We examined host usage and seasonal activity patterns of the nymphal stage of the ticks Ixodes kingi and I. sculptus within a prairie rodent community in north-central Colorado. Ixodes kingi was...

We investigated whether host-seeking nymphs and adults of the western blacklegged tick, Ixodes pacificus Cooley & Kohls, the primary vector of Lyme disease spirochetes in far-western North America,...

In California, dense woodlands have been recognized as important biotopes where humans are exposed to the nymphal stage of the western blacklegged tick, Ixodes pacificus Cooley & Kohls, the primary...

In California, Ixodes pacificus Cooley & Kohls nymphs have been implicated as the primary bridging vectors to humans of the spirochetal bacterium causing Lyme disease (Borrelia burgdorferi). Because...

The primary aims of this study were to quantify the density of Ixodes pacificus Cooley and Kohls nymphs and adults of the same generational cohort collected within a single year in six oak or madrone...

Risk of exposure to Borrelia burgdorferi sensu lato (s.l.) spirochetes, which include the causative agents of Lyme disease, is, in part, determined by the density of questing infected vector ticks....

We investigated the experimental vector competence of Ixodes pacificus Cooley and Kohls and Ixodes spinipalpis Hadwen and Nuttall, and the reservoir competence of the dusky-footed woodrat (Neotoma...

The aims of this review paper are to 1) provide an overview of how mapping and spatial and space-time modeling approaches have been used to date to visualize and analyze mosquito vector and...

Recent Rapid Rise of a Permethrin Knock Down Resistance Allele in Aedes aegypti in México
García, Gustavo Ponce, Flores, Adriana E., Fernández-Salas, Ildefonso, Saavedra-Rodríguez, Karla, Reyes-Solis, Guadalupe, Lozano-Fuentes, Saul, ...
Pyrethroid insecticides prolong the opening of voltage-dependent sodium channels in insect nerves to produce instant paralysis and “knock-down.” Many insects have evolved knock-down resistance...
