[Rearing the common housefly Musca domestica (L.) in small cages].

A simple and time-saving rearing method of the house fly (M. domestica L.) is described. Additionally a brief review is given on some manual techniques in breeding of flies. Rearing is carried out in small cages, which are completely supplied from outside. This method is especially suitable in case of many strains kept together in small rooms. Breeding is done in wire-frame cages in shape of a truncated pyramide covered with dederon wire-gauze. Flies are fed and lay eggs through the gauze. The breeding medium of larvae consists of wheat bran, fresh curdled whole milk and water with addition of dried yeast and methylhydroxybenzoat. Pupae weigh 25 to 31.5 mg, when stocking of the medium with larvae is near the optimum (1 larvae/1 g medium). The small cages admit 500 to 3,000 flies each.
