    Feeding activity, a study of control measures, and a survey of black fly pests (Dipterai Simuliidae) of horses in Virginia
    Townsend, Lee Hill (Virginia Tech, 1975)
    The feeding activity of female black flies may cause considerable annoyance to saddle horses. Horses under attack become head-shy and difficult to manage, posing a potential hazard to riders. Stabling horses offers a means of protection against black fly feeding, but most horse owners cannot or will not stable their animals to prevent disturbance by noxious flies. Because stabling is an unsatisfactory control measure, I will evaluate various ear protectants to find easily applied materials of suitable effectiveness and duration on pastured animals to be of practical value to the owners.

    The synthetic pyrethroid Ectiban permethrin as a treatment in the pest management of flies in caged-layer poultry houses
    Townsend, Lee Hill (Virginia Tech, 1977)
    The objective of my research was to evaluate the synthetic pyrethroid permethrin (Ectibantm permethrin, ICI, Americas, Inc.) (Fig. 1) as a potential treatment in the integrated control of synanthropic flies in poultry houses. I used a variety of application techniques including feed additive, direct topical application to manure for larval control, and residual sprays for adult control. In addition to investigating the effects of the pyrethroid on the house fly, I determined its effect on selected nontarget parasites and predators which may occur in chicken houses. The goal of the research is potent insecticide compatible with an integrated control approach for synanthropic flies.
