A Renewed Way of Malaria Control in Karnataka, South India

LARVAL SOURCE MANNGEMENT Larval source management (LSM) in vector control has not got much importance due to various factors. The major reason was the lack of confidence in employing at the grass root level. In rural settings, besides scattered human settlements, there are vast breeding habitats of mosquitoes. In the beginning of the twentieth century, LSM was the only method of vector management, and got less importance after the arrival of DDT. It lasted for almost four decades, and it was realized the need of the alternate strategy when there was a resurgence of malaria in the mid 1970s. Even today LSM has received a low profile in vector management. Fillinger and Lindsay (2011) have given a detailed account on the use of this strategy, and pointed out that most of the developed nations are using this strategy to manage mosquito control. They questioned why this strategy has not got due importance in the African countries where the real problems exist.
