(Diptera: Muscidae) over two summers. Horn flies were netted from cattle every 3–4 d for 2 wk before treatment, 2 wk during treatment (four treatments, with flies collected before each treatment), and 2 wk after treatments ceased. Blood meal weights were estimated by hemoglobin assay of excised abdomens. Other females were dissected to determine the number of active ovarioles and the stage of primary follicle development. Depending on year and herd, pretreatment males contained an average of 0.6–1.0 mg of blood, while females contained 1.7–2.7 mg. Pretreatment egg development (least developed oocytes were stage 1 and fully developed eggs were stage 5) averaged 3.7–4.3, and number of active ovarioles averaged 18.1 to 19.6/female. During treatment periods, significant reductions in blood weight were noted for females, but usually not for males, and females also often exhibited reduced mean oocyte stage and number of active ovarioles. Peaks in proportions of young nulliparous females (oocyte stages 1 or 2) were seen during some repellent application periods. This suggested older females had been killed or driven off from the local population by the treatments, and flies on cattle included more young flies that likely were recent arrivals. The repellent-oil mixture thus impacted blood feeding, reproductive fitness, and probably age structure in the field.}, number={2}, journal={JOURNAL OF MEDICAL ENTOMOLOGY}, author={Mullens, Bradley A. and Soto, Diane and Gerry, Alec C. and Fowler, Fallon E. and Diniz, Alesha N.}, year={2018}, month={Mar}, pages={408–416} }
 @article{fisher_fowler_denning_watson_2017, title={Survival of the House Fly (Diptera: Muscidae) on Truvia and Other Sweeteners}, volume={54}, ISSN={["1938-2928"]}, DOI={10.1093/jme/tjw241}, abstractNote={Abstract The house fly, Musca domestica L. (Diptera: Muscidae), is a disease vector of mechanically transmitted pathogens including bacteria, viruses, and protozoans. Opportunities for pathogen transmission can increase as fly longevity increases. Dietary preferences play an important role in insect longevity; therefore, we investigated house fly preferences, sucrose availability, and caloric constraints on house fly longevity. Experimental goals were: 1) to test the effects of calorie restriction on survival of house flies by manipulating concentrations of erythritol (low caloric content) and sucrose (high caloric content), and comparing commercial sweeteners of differing calorie content, 2) to identify house fly preferences for either erythritol or sucrose, and 3) to evaluate the insecticidal activity or toxicity of erythritol on house flies. Our data show that house flies may prefer high calorie options when given a choice and that house fly longevity likely increases as calorie content increases. Additionally, no significant differences in longevity were observed between the water only control (zero calories) and erythritol treatments. This suggests that decreased survival rates and death could be the result of starvation rather than insecticidal activity. This research furthers our understanding of house fly survival and sugar-feeding behavior.}, number={4}, journal={JOURNAL OF MEDICAL ENTOMOLOGY}, author={Fisher, Michael L. and Fowler, Fallon E. and Denning, Steven S. and Watson, David W.}, year={2017}, month={Jul}, pages={999–1005} }

Face flies were common only at Pomona (34°03′N, 117°48′W). Other irrigated pastures, even those only slightly inland from Pomona, were probably too warm for face flies, due to a steep west (cooler) to east (warmer) temperature gradient. Horn flies were abundant at all sites. Adult densities on cattle, adults emerging from dung pats, and prevalence of fly-positive pats were assessed for both fly species throughout a year at Pomona. Summer adult horn fly densities of 500–2,000 flies per cow, or face fly densities of 3–10 flies per face, were common. Summer prevalence of face fly-positive pats and horn fly-positive pats was about 20–40% and 30–70%, respectively. Face fly adults diapaused from late October until late March and early April. Horn flies probably diapaused as pupae from late October or early November to early-mid March, although some emerged in winter. Experimental cohorts of October-emerging adult face flies were held in a representative overwintering site. They exhibited hypertrophied fat body and undeveloped oocytes, which are characteristics of diapause, and survived until the following spring. The dominant diapause cues in face and horn flies are probably photoperiod and temperature. Despite warm winter temperatures that would permit activity of both species, and despite relatively long winter day lengths, face flies and most horn flies still diapaused at this latitude.}, number={6}, journal={JOURNAL OF MEDICAL ENTOMOLOGY}, author={Fowler, Fallon E. and Chirico, Jan and Sandelin, Broc A. and Mullens, Bradley A.}, year={2015}, month={Nov}, pages={1213–1224} }
