  Dengue is a vector-borne disease transmitted by the mosquito Aedes aegypti.
It has been observed that its incidence is strongly influenced by temperature
and other abiotic factors like rainfall and humidity. In this work we compare
the effects of seasonality in temperature that affect the entomological
parameters of the mosquito with precipitation that affects the hatchery
capacity. We also analyze its joint action using a dynamical model for the life
cycle of Aedes aegypti and historical weather data from 8 regions of Mexico. We
found that the joint action of different mechanisms can enhance the prevalence
of the disease, but also inhibit it when they act in an asynchronous way. We
found that for the studied regions, the seasonality of the low temperature
rather than mean temperature is the main driving force of Dengue outbreaks. We
also analyzed the role of the diapause in these kinds of outbreaks. The
methodology developed here can be used to discover the underlying mechanism of
Dengue outbreaks in different regions and thus help to apply targeted control
measures.
