Aim: This study aims to identify the relation between the physicochemical factors of water and the number of larvae contained in each natural breeding site (phytotelmata).

Method:  Cross sectional study by stratified random sampling was conducted from January to May 2017. Water samples were obtained from 6 residences with the highest or hyperendemic dengue cases. The observed water parameters include temperature (oC), turbidity (NTU), carbon dioxide (ppm), ammonia (ppm), nitrate (ppm), sulfate (ppm), pH, and DO (ppm). Data was then analyzed to determine its correlation with the number of larvae. The data analysis applied IBM SPSS 21. Komologrov-Smirnov was used for the normality test prior to the correlation test with Spearman correlation.

Results: 691 Ae.albopictus larvae and 23 Ae.aegypti larvae were obtained. There were 55 natural breeding sites(phytotelmata) for Aedes aegypti and Aedes albopictus, these phytotelmatas were divided into 4 categories: axillary leaves, tree holes, bamboo stumps, and fruit peel. It can be seen from the results that the DO parameters showed a significant relationship with the number of larvae (p = 0.039).

Conclusion The distribution of phytotelmata types in each Kabupaten varied, but did not differ significantly. Of the 8 parameters studied, only the DO parameters showed a significant relationship with the number of larvae (p = 0.039), while the other parameters such as temperature (p=0,054), turbidity (0,97), carbon dioxide (0,38), ammonia (0,87), nitrate (0,6), sulfate (0,54), and pH (0,62) showed no significant relationship.
