Mediterranean fruit fly, Medfly |
Ceratitis capitata |
ARS scientists in Hilo, Hawaii are collaborating with ARS researchers at Weslaco, Texas, to investigate phloxine B, better known as the FDA-approved red dye number 28. The dye, might prove a safe, effective alternative to today's malathion insecticide. Medflies often share regurgitated food. This helps spread the insecticidal dye-and-bait blend through the population. |
