Insecticide Resistance and Management Strategies in Urban Ecosystems.

The increased urbanization of a growing global population makes imperative the development of sustainable integrated pest management (IPM) strategies for urban pest control. This emphasizes pests that are closely associated with the health and wellbeing of humans and domesticated animals. Concurrently there are regulatory requirements enforced to minimize inadvertent exposures to insecticides in the urban environment.

Survey of Pest Management Practices on Washington Dairy Farms.

Washington state dairy producers were surveyed to determine pest and parasite prevalence and range of current pest management strategies. Nearly all respondents reported treating their cattle or premises for flies, while 62% reported treating their animals for external parasites. Use of pyrethroid and pyrethrins insecticides was common throughout the state.

Use of a highly sensitive immunomarking system to characterize face fly (Diptera: Muscidae) dispersal from cow pats.

We tested an immunomarking system that used egg white as marker and enzyme-linked immunosorbent assay as a detection assay to characterize face fly (Musca autumnalis DeGeer) dispersal from cow pats in a pastured beef cattle operation. In microcage assays, adult flies acquired marker after contact with cow pats that were treated with marker and field aged up to 11 d. In arena assays on sprayed full-size cow pats, 77% of eclosed face flies acquired the marker.

Evaluation of sunlight-exposed pyrethroid-treated netting for the control of face fly and housefly (Diptera: Muscidae).

Background: Face flies, Musca autumnalis De Geer (Diptera: Muscidae), and houseflies, Musca domestica L. (Diptera: Muscidae), have a significant impact on livestock and dairy production throughout North America. Pyrethroid insecticide efficacy can be affected by exposure to direct sunlight, and the rate of photodegradation is substrate and formulation dependent.
