Carryover Effects of Thermal Conditions on Tick Survival, Behavior, and Simulated Detectability.

ABSTRACT: Carryover effects occur when environmental history of an organism influences its behavior, fitness, and population dynamics. Carryover effects have received some attention in the field of vector-borne disease ecology but are understudied in the context of ticks and tick-borne pathogen transmission where they may influence tick-host contact, pathogen transmission, and tick surveillance. Using controlled lab studies, we investigated how recent thermal history affects mortality and activity of adult Amblyomma americanum, an emerging vector of human and animal pathogens. To characterize thermal carryover effects on tick detection, we used our laboratory data to parameterize a simulation of tick trapping in the field. Ticks exposed to warm conditions for 4 weeks subsequently exhibited an
