ABSTRACT

 

Although individual protection from bites of adult nopheline mosquito, by smoke and other fumigant devices was well known in the past, large scale use of insecticides proved to be unexpected by successful since last 40 years in India. Insecticides acts slowly and some of them irritate the mosquitoes, leading to their flight towards the light and usually out of the domestic places. Large scale application of insecticides, will have a marked effect on those Anopheline species of mosquitoes, which preferably feed on man or take shelter in human dwellings, sheds of domestic animals. In Anopheline mosquito population which are susceptible to the insecticidal action are gradually killed and thus the proportion of the resistant mosquitoes are able to increase very rapidly. Now a days the great increase of resistance of mosquitoes to chlorinated hydrocarbons, organophosphates and carbonates has stimulated some attempts to produces compounds of different concentration and structure. The dosage and cycles of their application should in such a way (3%,4%,5%. DDT Malathion, Pyrethrum) that only the mosquito population involved in the transmission of malaria is affected or killed. WHO test kite used in this approach.
