Interpretive Summary: Toxicant systems that use insecticide-impregnated orlon yarn applied to fiberglass traps were devised in the 1980's for killing stable flies. But the length of time the yarn would continue to kill flies was not measured. Our tests showed that the impregnated yarn would kill stable flies for approximately 8 weeks under simulated field conditions. A relatively new trap with a cylindrical configuration was found to be acceptable for use with the impregnated yarn. By leaving impregnated yarn in the field for no longer than 8 weeks, the potential for development of pesticide resistance by the flies is minimized. Toxicant devices with pesticide-impregnated yarn could be used by cattle producers, both beef and dairy, to manage stable fly populations, with minimal amounts of pesticides being released into the environment.

Technical Abstract: A series of tests were performed to determine how long permethrin- impregnated yarn applied to fiberglass panels would remain effective as a killing device for stable flies. In simulated field tests, yarn remained effective for about 8 weeks, indicating that it should be in the field for no longer than 8 weeks to minimize the development of insecticide resistance in stable fly populations. A cylindrical trap configuration on which the impregnated yarn might be applied was tested and found to be suitable for this use.
