Abstract

Two trials were conducted in the Anca and Paku areas of the Lindu valley, Central Sulawesi against the schistosomiasis intermediate host Oncomelania hupensis lindoensis. The trials were conducted in sequence. Application of bayluscide monthly at 10-40 ppm for one year suppressed 50% of the snail population density in Anca and 23% in Paku. Application of bayluscide monthly at 10-40 ppm com­bined with installing drainage canals following the above mentioned trials reduced the snail population density in Anca 61% and 94% in Paku.
