During a period of two years a total number of 1998 mosquitoes were collected and examined. Percentage density of different genera was found as Anopheles-64.71%; Aedes-19.61%; Culex-11.61% and Mansonia-4.05%.  Key words: Mosquitoes, Jalna, diversity, Anopheles   Introduction Mosquitoes play an important role in spreading diseases, Anopheles-Malaria, Culex-bancroftain falariasis, Japannese encephalitis, Aedes-dengue and chikungunya fever, Mansonia-Malayan filariasis and chikungunya fever. Mosquitoes belong to class insect, order Dieptera and family culicidae. This family contains about 3500 species in three sub families anophelinae (3 Genera) and culcincae (at least 37 Genera), and the toxorhynchitinae (1 Genus). Mosquitoes play an importent role in ecosystem like food for aquatic organisms and they are vectors for various diseases. In most of the species females suck blood from the hosts. The mosquitoes are variable in their sizes. Mosquitoes weigh from 2-2.5mg. They can travel up to 1-2km/hr and reach at most up to 11 kms in search of food and mate. Most of the species are nocturnal or dawn or evening feeders (Jawetz, 1987). Jalna city is situated at the center of Maharashtra State and in northern direction of marathwada region. It lies between 19 O1 north to 21O3 north latitudes and 75O4 east to 76O4 east latitude.  Materials and methods The mosquitoes were collected from five sampling sites by using different aspirators and nets, resting boxes and repellents during the morning and evening hours.  A search for adult mosquitoes was made in every possible habitat like human dwelling, cattle shade, sites such as bushes, discarded containers and garbage dumped wet lands. After collection, samples were immobilized with 70% alcohol followed by their sorting up to genera level and their photography using dissecting microscopes and digital cameras. Identification was based on adult characters using standard taxonomic key and catalogues of mosquitoes identification key of Christopers (1933) and catalogue of Nagpal and Sharma (1995).   Results and Discussion Table 1,2, 3, 4 and 5 shows that during a period of  one years a total number of  1998  mosquitoes were examined. Percentage density of different genera was found as-Anopheles-64.71%; Aedes-19.61%; Culex-11.61% and Mansonia-4.05%. There are four genera found in Jalna urban at all the four sampling sites chosen. The present work states that the Anopheles mosquitoes were most abundant in number and their density that is, 64.71% followed by Culex i. e. 19.61%, Aedes 11.61% and Mansonia was lowest that is, 4.05%. The seasonal pattern of prevalence suggests that the maximum was during Jun Sept, followed by Oct-Jan. and lowest in the Feb-May2009. Anopheles mosquitoes are most dangerous amongst the four genera and are responsible for spreading of Malaria. Discarded coconut containers are the ideal breeding sites for Aedes mosquitoes which are dangerous because they are vectors for chickungunya and dengue fever. Culex mosquitoes are vectors for viral arthritis and bancroftain filariasis. Mansonia mosquitos are vectors for Malayan filariasis. There is acute need of action to reduce the breeding sites of mosquitoes and public awareness regarding mosquitoes and the diseases caused by them.  Table 1.
