2008 Annual Report
In spite of being used in California for the last 30 yr and for many eradication programs throughout the Pacific, male annihilation with methyl eugenol was still not legally available in Hawaii for control purposes except on an experimental basis until now. In 2008 the first provisional methyl eugenol end product registration for the Dow AgroScience product SPLAT-MAT-ME spinosad sprayable formulation was obtained by ARS scientists in the Tropical Plant Pests Research Unit in Hilo, HI through the US Environmental Protection Agency. The product will reduce the use of organophosphate insecticides, improve area-wide control of oriental fruit fly, and help guarantee sustainability of the Hawaii Area-Wide Pest Management program after ARS funding ends in FY-08. This environmentally friendly product will impact fruit fly control worldwide.

The 2007 invasion of the African continent by Bactrocera latifrons shows that there is an invasion threat posed by this species, which has been established in Hawaii for over 20 years, but for which little research had been directed toward developing methods of control. Through research efforts by scientists at the Tropical Plant Pests Research Unit, U.S. Pacific Basin Agricultural Research Center, with collaboration with scientists at the University of Hawaii, potentials for control of B. latifrons were documented in the areas of biological control, male annihilation and use of bait sprays. Natural parasitization rates of B. latifrons were found to be very low in Hawaii suggesting that efforts to improve the effectiveness of biological control against B. latifrons may help in the field. Additionally, male B. latifrons were found to show significant response to alpha-ionol + cade oil before the age of sexual maturity suggesting that male annihilation could contribute to population suppression of B. latifrons. Finally, protein bait sprays were found to have good effectiveness against B. latifrons and offer, at present, the best tool for population suppression. These results provide approaches for field suppression that could potentially minimize the impact of this species in Hawaii and in areas where B. latifrons invades.
