There are many diseases which are transmitted by mosquitoes as vectors. The presence of mosquitoes is widespread throughout the world including in Indonesia with an estimated 3100 species from 34 genera. Vector control is the main thing to do in addition to treatment in patients. Morphological identification of mosquitoes aims to identify the character and number of species so that it becomes a picture of diversity in an area. Data collection was carried out by collecting data from the 2015 Special Research Report on Vector and Reservoir Diseases (Rikhus Vektora) in Central Java Province. The data obtained were analyzed descriptively. Mosquito samples in Rikhus Vektora in 2015 in Central Java Province were collected from 3 different ecosystems, namely forest (H), non-forest (NH) and beach (P).
