An evaluation of the larvicidal effects of ORIGIN 3-6-9.
The effect of ORIGIN 3-6-9, a combination of fatty acids and amino acids derived from castor beans, was evaluated against Aedes albopictus larvae in water containing varying concentrations of this compound. At rates above 50 ppm, it caused 100% mortality, whereas at 5 ppm or less, larval mortality was not significantly different from that of the control. Tests repeated at 7, 14, and 28 days posttreatment demonstrated no reduction in effectiveness against the test species.
