Tsetse flies as tools for minimally invasive blood sampling

Abstract

Collecting blood samples is an important aspect of wildlife studies where data on physiological parameters are required. To avoid stress to the test animals and its potential influence on the test parameters, minimally invasive blood sampling offers numerous advantages. Here, we describe using the African tsetse fly (Glossina brevipalpis) to sample blood from meerkats (Suricata suricatta) habituated to human presence. Prior to the experiments, test animals were trained with positive reinforcement to tolerate a box that enclosed the insects being attached to their neck. This method allows drawing blood samples at defined points of time and from specific individuals during captive studies. Additionally, because it presents the first example of an African haematophagous insect suitable for sampling blood, African field studies might benefit from this minimally invasive blood‐sampling technique without the risk of importing potentially invasive species. © 2013 The Wildlife Society.

Towards more compassionate wildlife research through the 3Rs principles: moving from invasive to non-invasive methods

“…While not completely non-invasive method, blood-sucking insects have been used as a 'gentle' stress-free method of DNA collection in several mammalian species (Voigt et al 2005, Calvignac-Spencer et al 2013, Habicher et al 2013, Lee et al 2015, Rodgers et al 2017, so-called invertebratederived DNA (iDNA). The potential of using terrestrial leeches (Haemadipsa spp.)…”
