RESUMO
Sandfly fauna of three districts of Rajasthan representing arid and semi-arid environments are described. A total of 2,042 sandflies belonging to two genera and seven species were collected. The arid district of Bikaner with irrigational development (by means of canal) showed considerably higher density of species Phlebotomus papatasi (16.5 PMH) as compared to Jodhpur district (1.0 PMH). The species encountered were Ph. papatasi, Ph. sergenti, Sergentomyia punjabensis, S. babu babu, S. clydei, S. bhagdadis and S. christophersi.

A survey undertaken in two desert (Jodhpur and Bikaner) and one non-desert (Jaipur) districts of Rajasthan indicated that medically important mosquitoes comprised of three genera and elevan mosquito species. Culex pseudovisbnui, C. malayi and Anopheles culicifacies were found in desert districts only and A. fluviatilis, C. gelidus and Aedes vittatus in non-desert Jaipur district only. Except A. subpictus, all the species in the desert region had peak density in RH range of 21-60 per cent while in non-desert area most of the species had highest density in RH range of 61-80 per cent. No species in non-desert area occurred at temperature more than 40 degrees C.

Plasmodium malariae infection was detected in Bastar district (M.P.) during malaria survey in 1981-83. The data collected during the survey was compared with the earlier records of P. malariae infection in the area. From the data it can be seen that the infection in this area has declined due to the ecological/developmental activities undertaken by Government. All the cases were found to be indigenous and approximately 62 per cent infection was found in age group of 10-14 years irrespective of sex. More than 60 per cent of P. malariae infections were positive for gametocytes. Three day regimen of 4-aminoquilines for the treatment was found quite effective.
