Abstract

Mesocyclopssp.is the zooplankton which include in crustacean class. They are effectively become as biological agent to control mosquitoe larvae. The treatment in this study was using Ipomoea reptana and Eichhornia crassipes as food sources and immersion time (5, 10, 15, 20 days). Concentration of media were used Food Sources : PDAM water (1 : 9) with the difference immersion time. The parameter observed were long period of the life cycle, survival ability and percentage ofMesocyclopssp. offspring produced. The result showed thatIpomoea reptana and

Eichhornia crassipesas food sources and the difference immersion time took effect on the fastest period of the life cycle for 16 days on Eichhornia crassipes 20 days. Survival ability is need Mesocyclops sp. from copepodit to mature stage the value 76 % onEichhornia crassipes20 days. Interaction between Ipomoea reptana and Eichhornia crassipes as food sources and immersion time gave the highest tiller produce (p<0.05) with an average of 32 head/individual onEichhornia crassipes20 days.
