§    ABSTRACT: The dengue is a tropical disease transmitted by the female of the mosquito Aedes aegypti, for which a vaccine doesn't exist. In countries as Brazil, the control of the disease is made through the control of the mosquito. An important aspect of this control is, undoubtedly, the understanding of the cycle of life of this mosquito. Therefore one of the main objectives of this work is to study the oviposição. In such way, is important to understand details related to the amount of put eggs, in order to control the proliferation of the mosquito.  The aim of this work is to analyze the number of eggs of the mosquito Aedes aegypti by means of models for count data.  After the introduction of the statistical models, we will obtain maximum likelihood estimates of the parameters to these models and we will check the hypotheses of interest using test score. We will make a graphical analysis to identify the behavior of the models studied in order to verify the adequacy of these models subject to the number of eggs of the mosquito Aedes aegypti.

§    KEYWORDS: Excess of zeros; negative binomial; Poisson; dengue; maximum likelihood estimates; score test.
