Abstract

It is an open question whether the activity of host-seeking ticks is under endogenous circadian control or arises entirely as an exogenous response to external stimuli. We experimentally evaluated the chronotype of locomotor activity in individual unfed adult Dermacentor variabilis. Two major activity peaks in locomotor activity arose in response to an evenly split 24-hour photic cycle. Most individuals had either a chronotype with exclusively nocturnal activity or with both nocturnal and diurnal activity components. Our results indicate that diurnal behavior has an endogenous basis but suggest that nocturnal behavior is driven by an exogenous response to the photic cycle.

期刊介绍： Ticks and Tick-borne Diseases is an international, peer-reviewed scientific journal. It publishes original research papers, short communications, state-of-the-art mini-reviews, letters to the editor, clinical-case studies, announcements of pertinent international meetings, and editorials. The journal covers a broad spectrum and brings together various disciplines, for example, zoology, microbiology, molecular biology, genetics, mathematical modelling, veterinary and human medicine. Multidisciplinary approaches and the use of conventional and novel methods/methodologies (in the field and in the laboratory) are crucial for deeper understanding of the natural processes and human behaviour/activities that result in human or animal diseases and in economic effects of ticks and tick-borne pathogens. Such understanding is essential for management of tick populations and tick-borne diseases in an effective and environmentally acceptable manner.
