Produktbeschreibung
Excerpt from Flies and Mosquitoes, as Carriers of Disease It is now well known that the common house fly and the mosquito are not merely nuisances but enemies to mankind and positive dangers to health by becoming at times the medium for disseminating disease germs. We hear much of flies being the indirect cause of typhoid fever, and of some species of mosquitoes causing malarial fever. Both typhoid fever and malaria, though occurring to some extent in cities, are considered to be chiefly country or farm diseases; hence this subject ought to interest the farmer. It is not necessary for our purposes to explain at length how diseases are transmitted by insects. Suffice it to mention that some insects, like flies, carry disease mechanically by transferring the germs by means of their bodies, wings and feet from human excreta to our food, while others, like some species of mosquitoes, become the host of disease germs, with which they inoculate human beings through their bite. It is now firmly asserted that one species of the mosquito, the anopheles, is the only contributing cause of malaria, and that this illness may be entirely avoided by preventing persons from being bitten by infected mosquitoes of this species. Taking the above statements as a basis, we wish to point out that on many farms, in farmers houses and about their barns, flies abound in warm weather, while in other country localities the life of the occupants of farm cottages is rendered miserable by the ravages of mosquitoes. While both flies and mosquitoes are bad enough at certain times in the city, they constitute in agricultural districts a veritable pest, a source of annoyance to horses, cattle and men, a cause of physical discomfort, such as loss of sleep, and a nuisance whereby health may become seriously affected. Let us see, then, how far in rural districts the evil can be controlled, and inquire what the farmer can do to assist in the crusade aiming at their extermination. Let us study what conditions are met with in the country and on the average farm, which favor the existence and breeding of both flies and mosquitoes. Let us explain what remedial measures can be readily applied by the farmer who anxiously seeks for improved surroundings.
