. Annals of the Entomological Society of America. Entomology. DISPERSAL OF MUSCA DOMESTICA LINNE. James Zetek, Ancon, C. Z. The latter part of May, 1913, unusual numbers of flies appeared at the Isthmian Canal Commission hotels and com- missary at Balboa, Canal Zone. An inspection revealed a pile of cow manure, etc., about 800 square feet in area, located at one corner of Ancon Cemetery, 2,500 feet distant in direct line from the hotel. This place is indicated by the letter "B" on the accompanying map. This manure was heavily infested with maggots, principally of Musca domestica, Hermeiia illucens, Volucella obesa, and Paralucilia macellaria. Puparia were very abundant and adults in countless numbers. This was the only manure pile found away from the Fig. 1. Map of the region. A pit was dug, into which was placed a small quantity of the infested manure. A cover of earth one foot deep was added as a protection from heat rays. Over this was placed a screened cage. On June 6th the cage contained about five thousand adult flies, most of them the common typhoid-fly. At 9:00 a. m. these were sprayed with an aquaeous solution of gentian- 70.
