Abstract in Portuguese
O presente trabalho teve por objetivo estimar o tempo que os ovos de Aedes aegypti permanecem em condições de eclodir e produzir larvas viáveis após permanecerem armazenados por determinado tempo ( viabilidade) em diferentes tipos de recipientes. Para tal, usou-se a metodologia dos modelos lineares generalizados para dados na forma de proporção. Como função de ligação, optou-se pelas funções logística e probito, como preditores lineares retas paralelas e retas concorrentes. Foi realizado um experimento, em que procurou-se simular, tanto quanto possível, o efeito das condições ambientais que os ovos de Aedes aegypti são submetidos. Os ovos foram armazenados em três recipientes (copo plástico, saco plástico e envelope de papel) e tratados com água ao final de cada período de armazenamento estabelecido. Por meio do ajuste do modelo linear generalizado binomial com função de ligação logística e preditor linear retas paralelas, foi possível predizer a viabilidade dos ovos de Aedes aegypti. Como medidas da qualidade do ajuste, usou-se o desvio residual com valor de p (nível descritivo), calculado sobre os percentis da distribuição qui-quadrado e o gráfico de probabilidade normal padrão com envelope de simulação. Verificou-se comportamento semelhante entre saco plástico e envelope de papel com respeito a viabilidade estimada dos ovos de Aedes aegypti, ambos diferindo do recipiente copo plástico que apresentou a maior viabilidade.

Abstract in English
This work had like objective estimate the time in which the Aedes aegypti eggs remain in hatch conditions and produce viable larvae after remain a certain time (viability) in different storage types. To this, the generalized linear models methodology for data in proportion form was used. As link function was chose the logistic and probit and like linear predictors, parallel and intersecting lines. Was conducted an experiment, in which were simulated as much as possible the effect of environmental conditions in which the Aedes aegypti eggs are submitted. The eggs were stored in three containers (plastic cup, plastic bag and paper envelope) and treated with water at the end of each storage period. With the fit of the binomial generalized linear model with logistic link function and parallel lines like linear predictor, was possible predict the viability of the Aedes aegypti eggs. As quality measures of fit, the residual deviance with p-value (descriptive level), calculated on the chi-square distribution percentiles and the standard normal probability plot with simulated envelope were used. It has been found similar behaviour between plastic bag and paper envelope with respect to estimated viability of the Aedes aegypti eggs, both differing from the plastic cup that presents the highest viability.
