Man vector contact in microfilaraemic and amicrofilaraemic human population--a case control study.

A case control study was undertaken in rural areas of Varanasi, U.P., to study the relationship of Culex quinquefasciatus landing on microfilaria--carriers and amicrofilaraemic controls. No statistically significant difference was observed in the vector landing in these two groups.

Larvivorous fishes in controlling mosquito breeding from draw wells.

Culex quinquefasciatus have been found to breed in about 29 per cent of the wells in semi-urban area and 14 per cent of the wells in rural areas of Varanasi at one time or other. Majority of such wells are used-ones. Effectiveness of Poecillia reticulata, Esomus danrica and Trichogaster fasciatus in controlling well breeding is evaluated in the present study with successful results.
