The degree of different location will result the different temperature and humidity. The Ngringo village of Jaten sub district is located at 98 meters over surface sea level and Karanganyar village of Karanganyar sub district is 480 meters over surface sea level, they are the endemic village of DHF. In 2003, the Ngringo village had IR = 0,75 per 10,000 population and Karanganyar village was not found DHF cases. The objective of this research is to analyze characteristic difference of areas any at both high and low landscape.

Methods : This is an observational research using cross sectional design. The sample is 30 houses on Ngringo village and 30 houses on Karanganyar village, by applied ovitrap, larvae survey and capturing of Aedes Aegypti mosquitoes at the resting places surround the houses. Then, surgery was done to know parousity and dilatation. Data would be analyzed using chi square test at  = 0,05.

Results : The research found that the proportion of indoor and outdoor, the mosquito mosquito eggs , larvae, mosquitoes adult, parous mosquitoes and dilatation mosquitoes are more found at the low landscape than the high one. There is a difference of proportion of egg finding indoor (p = 0,001) between in the low landscape and the high one. There is no difference of proportion of egg finding outdoor (p = 0,09) between in the low landscape and the high one. There is a difference of proportion of larvae finding (p = 0,001) between in the low landscape and the high one. There is a difference of proportion adult mosquitoes finding (P= 0,001) between in the low landscape and the high one. There is a difference of proportion of parous mosquitoes finding (p = 0,001) between in the low landscape and the high one and there is no difference of proportion of dilatation mosquitoes finding (p = 1,00) between in the low landscape and the high one.

Conclusions : Same characteristics of mosquito are different between at the low and the high landscape. They are found higher at the low than the high landscape.
