Abstract:

A biological larvicide spherifix containing Bacillus sphaericus VCRC B 42 was investigated against Anopheles sundaicus in Klaces hamlet, Cilacap regency. This study was conducted to determine the effectivity of spherifix on An. sundaicus larvae at a dosage of 2.5 kg/Ha. Observations were conducted one day before application of the larvicide, 24, 36, 48 hours, day 4, 7, and 14 after application. The larval reduction rates were calculated using the formula of Mulia et al, 1971, and a reduction of the results were 16.69 % after 24 hours, 20.95 % after 36 hours, 34.07 % after 48 hours, 65.08 % after 4 days, 85.98 % after 7 days, and 90.81 % after 14 days. B. sphaericus has capabilities to function as a biological larvicide.
