MEDFORD MAIL TRIBUNE. MEDFORD. OR. 6 t : - ; Pestiferous Face Fly Found West Of Mississippi Washington - (Science Serv ice) - Face flies, the enemy agents that invaded New York from Nova Scotia in 1953, have . succeeded in pushing their psychological warfare campaign across the Mississip pi river into the central states. Although not known to be carriers of a fatal disease, these pests can worry a horse or cow to a frazzle by lapping up fluids around the eyes and nose and around open wounds. There are reports that horses are particularly hard to handle after irritating attacks from face flies, and that cows refuse to feed prop erly and their milk production drops. The face fly stayed in the New York state area until 1957-1958. Now, in three years, it has spread to every state east of the Mississippi river as far south as Ten nessee and West Virginia, and It is making a beellne for the West Coast. Minnesota, Iowa, Missouri and Nebraska have reported the pest. But western Pennsylvania is the hardest hit area at present. Not Too Much Known Entomologist W. G. Bruce of the U.S. Department of Ag riculture admits that not too much is known about the fly. There is no known effective control, but a mixture of syrup, water and DDVP is doing some good. DDVP is dichloro - diphenyl - vinyl phosphate. This fly does not attack In the shade, inside barns and other buildings. It usually stays out in the bright sun light except in the fall when the temperature drops. Some Canadian investiga tors believe this pest is as sociated with outbreaks of pink eye (infectious keratltl:), but this has not been proved. One reason the face fly has such a head start is that it looks much like the common house. fly. Farmers ignore It at first.' There are differences, however, in the head anatomy and in the veins of the wings. There is also a dl'ference In the mouth parts, since the lace fly does not ' bite, but rather laps up fluids. New Antibiotic Said Effective Against Staph London - (Science Service) -.A newly discovered antibi otic, demethylchlorte t r a c y cline (DMCT), shown to be nearly twice as effective against staphyloccal infection as the older antibiotic tetracy cline (TO, is reported In a study of its merits In the cur rent Issue of the British Medl . cal Journal. The report on this antibi otic, by a Boston and London medical team, states the new antibiotic may be "entirely new or prove to be related in structure and action to anoth er already known." Research has been in progress since DMCT was first reported three years ago by Dr. J. R. D. McCormick and his as sociates at the Loderle Labo ratories,, Pearl River, N.Y. Drs. Maxwell Finland of Harvard Medical School and L. P. Garrod of the Univer sity of London, aided in part hv a National Institutes of Health grant, report observa tions alter studying voluml nous works of researchers published and unpublished. M.riti Undaeidtd Although the final merits of this new antibiotic have not been decided, the invest!- gators-vpoint out the follow ina adVunlnecs: 1. DCMT has hiiih stability. 1 lie actlvilv against most bacteria exceeds that of TC by approximately two fold, (Only two daily doses are re quired, which Is an Important advantage for patients requir ing sleep.) 3. Urine elimination is less than half that of TC, allowing (inline concentrations of DMCT to remain in the blood for a much longer time alter dose.
