  Controlling diseases such as dengue fever, chikungunya and zika fever by
introduction of the intracellular parasitic bacterium Wolbachia in mosquito
populations which are their vectors, is presently quite a promising tool to
reduce their spread. While description of the conditions of such experiments
has received ample attention from biologists, entomologists and applied
mathematicians, the issue of effective scheduling of the releases remains an
interesting problem for Control theory. Having in mind the important
uncertainties present in the dynamics of the two populations in interaction, we
attempt here to identify general ideas for building release strategies, which
should apply to several models and situations. These principles are exemplified
by two interval observer-based feedback control laws whose stabilizing
properties are demonstrated when applied to a model retrieved from [Bliman et
al., 2018]. Crucial use is made of the theory of monotone dynamical systems.
