Ecology and control of the principal flies associated with a compost plant

Summary:	Seasonal fluctuations of Diptera indigenous to domestic solid waste were examined at the Gainesville, Florida, municipal compost plant during 1968-1969. Population of both immature and mature forms were estimated and the efficiency of chemical and physical control procedures was tested. Adult dispersal studies were conducted during 1970 at the city landfill. The major fly source at the compost plant was found to be from larvae-infested incoming refuse. The greenbottle blow fly, Phaenicia cuprina (Shannon), comprised more than 90 percent of the larvae which migrated into protected areas where they developed into adults. Approximately 450,000 adult flies per week were produced during the summer months. This figure could be reduced by more than 63 percent by procedural and good housekeeping. The daily application of dichlorvos sugar bait reduced the number of flies by 66.7 per cent while a single application of dimethoare reduced the population by more than 50 percent for 1 week. {Illegible} were also effective as shown by laboratory tests. The number of house flies captured on sticky tapes was shown to be proportional to the number present in a large outdoor cage. Sticky tapes were used to show seasonal fluctuations of house flies in the digester building. House flies were the predominant insect breeding in compost. They were limited to the top 2.5cm in the digesters because of temperature. The optimum moisture content for house fly breeding was 75 percent to 14 percent of the eggs placed in compost at 45-55 percent moisture (normal operating conditions) developed into pupae. Egg survival to pupae decreased significantly when placed in refuse after 5-10 days of composting. P. cuprina males flew an average of 19,405.4 m and a maximum of 30,137 m when attached to a flight mill until death. Females flew an average of 25,235.2 m and a maximum of 45,030 m. Wild P. cuprina and M. comestica were marked and released 1 mi from a landfill and later recaptured at the landfill. An average of 10.17 percent of the wild P. cuprina and 1.66 percent of wild K. domestica released at the landfill on days followed by 24 hr without rain were recaptured 24 hr after release. An average of 10.7 percent of the wild P. cuprina released at the compost plant were recaptured in the same area 24 hr later. An average of 11.3 percent of laboratory-reared P. cuprina released at the landfill were recaptured 24 hr later. Baited traps surrounding the landfill recaptured only 2 flies after a total release of 255,000 flies.  Read more...
