2012 Annual Report


4. Accomplishments
1. Salivary gland hypertrophy virus of house flies. Flies prevent becoming infected from ingested pathogens by surrounding their gut contents with a protective, impermeable membrane. ARS researchers at Gainesville, Florida, improved the permeability of this membrane to salivary gland hypertrophy virus (SGHV) by giving the flies drugs that disrupt the membrane. This makes the flies more vulnerable to infection and the resulting knock-out of the fly’s reproduction. Results may lead to new methods for infecting flies with SGHV and other biocontrol agents that must be administered orally.

2. Parasitoids of stable flies and house flies. For many years there has been an ongoing debate over the best way to collect parasitic wasps that attack fly pupae on livestock farms. ARS researchers at Gainesville, Florida, developed a new method, the “improved sentinel station”, that allows collection of large numbers of wasps from closely targeted habitats. The new stations are highly sensitive and can be used to collect species that are rarely collected using traditional methods.

3. Color and contrast of insecticide-treated targets for stable fly management. When blue and black cloth targets were developed for use against tsetse flies, it was important to find blue cloth with pigments that would reflect sunlight in wavelengths most attractive to the fly. Using a target made of a blue cloth panel sewed to a black cloth panel was also considered important for maximum attraction. Recent work in Africa has shown that juxtaposition of blue and black cloth panels is not important and that black cloth worked fine by itself. ARS researchers in Gainesville, Florida, developing similar cloth panels to attract stable flies, needed to know if both cloth colors are necessary for maximum attraction. Capture rates for stable flies were not significantly different among blue/black, blue, or black cloth targets. Results will allow the use of targets of both colors or either color, depending on availability, cost, and desired use.

4. Insecticide-treated targets and flies as autodissemination vehicles for pyriproxyfen. ARS researchers at Gainesville, Florida, developing visual targets for a house fly attract and kill system, have switched from pesticides, to which most flies are resistant, to the growth regulator pyriproxyfen, an agent that blocks the development of immature fly stages so no adults are produced. When flies visit pyriproxyfen–treated surfaces, they carry the material with them and will deposit it when they lay their eggs, thus affecting the immature stages of other flies. Results could lead to development of self-treating stations and greatly reduce pesticide use.
