Abstract

Modeling in the logit and probit models necessary to predict the life of sundaicus Anopheles mosquito egg development. Comparison of the best model selected with the smallest error rate. This study uses secondary data from the study the influence of salinity on egg development of the Anopheles mosquito research sundaicus. The aim of research to know the difference logit model and probit model to predict the development of eggs of the Anopheles sundaicus mosquito. This study uses non-reactive methods, conducted from April to June 2011. Secondary data sources are data that uses 420 Anopheles mosquito eggs laid in 42 sundaicus tube / vessel. Each vessel contained 10 eggs of mosquitoes. Salinity set at levels of 5% -25%. All mosquito eggs set at pH 6-8 and is at a temperature of 20  C - 28  C, pH and temperature is optimal for the development of eggs of the Anopheles sundaicus mosquito. Results of analysis showed that the variable salinity and pH influence, whereas temperature had no effect on the development of eggs of the Anopheles sundaicus mosquito. P of the goodness of fit of all models of 0.00 <0.05 indicates that all the models that form does not fit Biossay method using probit or logit model is the best analysis to predict the dose response relationships or effect levels / specific dose of a particular response. Model selection is determined by some statistical considerations. If found an association of non linear transformations then it should be done with the log, so it found a better model.
