Spatial–Temporal Dynamics Of Stable Fly (Diptera: Muscidae) Trap Catches In Eastern Nebraska, David B. Taylor, Kristina Friesen, Jerry J. Zhu

Spatial and temporal relationships among catches of adult stable flies, Stomoxys calcitrans (L.), on sticky traps in eastern Nebraska were evaluated. Twenty-five alsynite sticky traps were placed in a 5 by 5 grid with 1.6-km intervals in a mixed agricultural environment from 2003 to 2011. Denser grids of 45-90 traps were implemented for varying lengths of time during the course of the study. More than two million stable flies were collected over 9 yr. Seasonal abundances based upon total collections from the primary grid of 25 traps were bimodal most years with population peaks in June and September or October. …

A commercial vinegar product (ChinKiang) was found to be highly attractive to adult house flies, Musca domestica L. Field experiments on a Nebraska dairy demonstrated that traps baited with vinegar and brown sugar captured more house flies than those baited with other house fly attractants. Solid phase microextraction was used in the field to collect volatiles from the vinegar bait. Seven compounds were identified as, acetic acid, furfural, butanoic acid, isovaleric acid, hexanoic acid, 2-phenylethanol, and p-cresol. Electroantennograms showed that the seven vinegar components elicited significant responses from antennae of female and male house flies. Bioassays indicated that the vinegar …

Although insecticide resistance is a widespread problem for most insect pests, frequently the assessment of resistance occurs over a limited geographic range. Herein, we report the first widespread survey of insecticide resistance in the USA ever undertaken for the house fly, Musca domestica, a major pest in animal production facilities. The levels of resistance to six different insecticides were determined (using discriminating concentration bioassays) in 10 collections of house flies from dairies in nine different states. In addition, the frequencies of Vssc and CYP6D1 alleles that confer resistance to pyrethroid insecticides were determined for each fly population. Levels of resistance …

The stable fly, Stomoxys calcitrans (Diptera: Muscidae), is one of the most important pests of cattle and costs U.S. cattle producers billions of dollars in losses annually. In this study, the efficacy of catnip oil encapsulated in gelatin in oviposition deterrence and larval growth inhibition in stable flies was examined under laboratory conditions. More than 98% inhibition of stable fly larval growth and female oviposition was observed in larval and oviposition media treated with encapsulated catnip oil (0.5 g). Further, dose–response tests showed that as little as 0.1 g of encapsulated catnip oil provided >85% oviposition deterrence. The release of …
