Tick surveillance

The surveillance of vectors and vector-borne diseases is essential for their control. Vector-borne diseases have a severe impact on animal and human health and many are expanding their range into new areas. Adequate surveillance systems are necessary to monitor disease outbreaks and introductions into new areas.

Tick sampling

Ticks are collected, sent to an appropriate laboratory alive, or preserved in ethanol (70%), then further processed. For surveillance purposes, ticks are trapped, identified, sorted by sex, age, physiological type etc., counted and stored for further studies.

Tick sampling /collection methods

Different sampling methods for ticks are available, some of them adapted to the biology and behaviour of the tick species that one wants to collect, while others are more general in a sense that they can be applied to collect a variety of ticks. Especially free-living ticks with a “hunting” behaviour, like Amblyomma species, are sampled using dry ice traps as they mimick the carbon dioxide produced by their hosts. Questing ticks like larvae of the one host tick Rhipicephalus (Boophilus) microplus, vector of bovine babesiosis and anaplasmosis, are sampled using the dragging apparatus. The parasitic stages (on-host) of most ticks species can be collected on the host itself.
