"[Deer Tick] nymphs, which will bite humans aggressively, are the main stage responsible for the transmission of disease to humans." The majority of larvae emerge from eggs in late spring and their peak period of activity is in the summer, predominantly August and September. There is also a...
The studies tended to find fewer ticks at the nymph stage, which is when they can transmit tick-borne encephalitis (TBE) virus and other diseases. But when they removed deer from smaller areas, they found more nymphs.Ivan OranskyThe Scientist...
Both have a dorsal plate on their back called the scutum, and their mouthparts are visible when viewed from above the tick. The males are slightly smaller than the females in the adult stage. Both species have six legs in the larval stage; eight legs in the nymphal and adult stages; ...
Acorn‐driven increases in the abundance of mice were correlated with a lagged increase in the abundance of questing nymph‐stage Ixodes scapularis ticks infected with Lyme disease bacteria. Abundance of white‐tailed deer 2 yr prior also correlated with increased density of infected nymphal ticks, ...
I. pacificus, the western black-legged tick, transmits the infection along the Pacific Coast. The ticks feed predominantly in the late spring and early summer during their nymphal stage, and Lyme disease usually results from bites of infected nymphs. Deer do not become infected but rather ...
and the consequential impacts on both the environment and public health. This contextual backdrop sets the stage for the two subsequent sections, which delve into specific examples of pathogen transmission involving white-tailed deer categorized by tick and mosquito vectors into tick-borne and mosquito...

Ixodes ricinus ticks usually become infected with TBEV in the larval stage and may, after one or more years as infective nymphs transmit the virus to humans. Thus, it is plausible that the temperature in the tick’s environment may affect the human TBE incidence after such a lag period of ...
The larval and nymphal stages of these ticks feed on a wide host range including small mammals such as the white-footed mouse (Peromyscus leucopus; a natural reservoir of B. burgdorferi), chipmunks and squirrels, birds, reptiles, and also larger animals such as white-tailed deer (WTD) (...
Transtadial survival of the babesia occurred between nymph and adult stages of the tick, and the adult stage transmitted the babesia.doi:10.7589/0090-3558-26.3.390Waldrup, K. A.Kocan, A. A.Barker, R. W.Wagner, G. G.J Wildl Dis...
