sub-Saharan Africa and are the target of the Pan African Tsetse
and Trypanosomiasis Eradication Campaign (PATTEC). Glossina
palpalis gambiensis (Diptera: Glossinidae) is a riverine species that
is still present as an isolated metapopulation in the Niayes area of
Senegal. It is targeted by a national eradication campaign combining
a population reduction phase based on insecticide-treated targets
(ITTs) and cattle and an eradication phase based on the sterile
insect technique. In this study, we used species distribution models
to optimize control operations. We compared the probability of
the presence of G. p. gambiensis and habitat suitability using a regularized
logistic regression and Maxent, respectively. Both models
performed well, with an area under the curve of 0.89 and 0.92,
respectively. Only the Maxent model predicted an expert-based
classification of landscapes correctly. Maxent predictions were
therefore used throughout the eradication campaign in the Niayes
to make control operations more efficient in terms of deployment
of ITTs, release density of sterile males, and location of monitoring
traps used to assess program progress. We discuss how the models’
results informed about the particular ecology of tsetse in the
target area. Maxent predictions allowed optimizing efficiency and
cost within our project, and might be useful for other tsetse control
campaigns in the framework of the PATTEC and, more generally,
other vector or insect pest control programs. |
