Book excerpt: Excerpt from A Maggot Trap in Practical Use: An Experiment in House-Fly Control It is the writer's intention here merely to point out that the disposal of manure on the platform maggot trap is but a slight modification of the method just mentioned. Figure 4 differs from a diagram given by Ringelmann only in the platform and in the outlets through which the drowned larvae may be washed into the cistern. Here is shown the cistern in which the liquid manure collects. Watering with the liquid manure adds to the heap the valuable Constituents of the urine and promotes the anaerobic fermentation. If it is true, as just suggested, that lack of oxygen and the presence of carbon dioxid render the manure unfavorable for the development of the larvae, it follows that compact heaping and watering, by excluding air and increasing the moisture content, also insure the greatest percentage of migration. As a matter of fact, compactness and high moisture content are the very factors which make the maggot trap mest effective, whether the explanation is to be found in the temperature, or moisture, or lack of oxygen.
