In this paper, we introduce a predator-prey model to analyze
the population dynamics of the Aedes aegypti mosquito which is fairly blamed
for the transmission of dengue in Cali, Colombia. The model describes an
interaction of an aquatic predacious species deliberately introduced into local
mosquito breeding habitat, where the Aedes aegypti immature stages (eggs, larvae, and pupae) are already present and constitute the prey population. The
model also accounts for local population of adult female mosquitoes (or mature stage) emerging from the breeding site. This population is considered
as a target for reduction by deploying an adequate predacious species since
only female mosquitoes are held responsible for transmission of dengue and
other vector-borne diseases. Having analyzed the model, we have derived the
mosquito survival threshold with predation as a function of predator’s biological
characteristics. The model’s parameters were adjusted to the average seasonal
temperatures of Cali, Colombia and explicit conditions for biological characteristics of prospective efficient predators were established. Numerical simulation
with introduction of an efficient predacious species in local mosquito breeding
habitats revealed the possibility of eventual mosquito extinction in such localities. Finally, some particular biological species were proposed as potential
candidates for efficient predators
