Ophyra aewesgeres (Wi ed. ) -- the black dump fly. The Ophyra 

 aenesaens laboratory colony originated from adults collected on a west 

 Florida poultry farm in December of 1976. Eggs were set in pans 25 cm 

 in diameter and 8 cm deep containing the fortified diet of CSMA, horn 

 fly dry mix, and water as shown in Table 4 of the results section. 

 Pupae were separated from the medium by flotation 7 days later, dried, 

 and placed in a colony cage as for house flies. Besides the water and 

 nasogastric mix put in the house fly cages (Table 5 of the results 

 section), adult dump flies were supplied with cane sugar and dry fish 

 meal . 



Eggs were collected in moistened fish meal from 5 _ to 7 _ day-old 

 females. Approximately 500 to 1000 eggs were set twice a week to 

 maintain the colony. 



Hevmetia '.Zlucens (L.) — the black soldier fly. This fly was 

 reared in the laboratory on many occasions, but attempts to colonize it 

 did net succeed. Females placed in jars readily laid eggs on moistened 

 CSMA or the screened jar lids. Eggs were then set in moistened CSMA as 

 for house flies. In the growth chamber, larval development required 

 25 days and pupation another 10 days. Eggs were set primarily to provide 

 a source of early instar larvae for testing purposes. Besides CSMA, 

 S. itluaens was reared in chicken feed, fish meal, and mixtures of fish 

 meal and CSMA, all moistened with water. 



Phormta regina (Me i gen) -- the black blow fly. This fly was 

 attracted to the laboratory during the cooler months of the year and 

 it was colonized for testing purposes. Females oviposited in moistened 

 fish meal. Eggs were set in a mixture of 1 part fish meal, 1.5 parts 

 CSMA, and 1.8 parts water. A medium of fish meal and water was
