Carbofuran is a carbamate pesticide that has known to possess adverse effects in soil organisms including earthworms that potentially lead to changes in nutrient cycling. However, little is known about the effects of carbofuran,either dirrectly or indirrectly, on the earthworm Pheretima javanica. This research is intended to know the effect of carbofuran at sublethal doses on the food consumption rate, assimilation efficiency and growth rate of Pheretima javanica worms. Six concentration levels of treatment were prepared by concecutively adding carbofuran granules as much as 0 mg (for control), 0.1mg, 0.2mg, 0.3mg, 0.4mg and 0.5mg into the worm foods (100 mg of cow manure). The feeding parameters were based on the dry weight of the worms, food given and remnant food, and worm feces (casts) during three days of treatment. Growth rate of the worms was based on the weekly weight gain of the young worm treated for eight weeks. The results showed the consumption rate decreased, assimilation efficiency increased and growth rate decreased significantly by the increased concentration of the pesticide (α = 0.05). Thus, it can be conclusively suggested that carbofuran (Furadan 3G) highly harmful to earthworms, even at low concentrations.
