ROVARTANI KÖZLEMÉNYEK (SERIES NOVA) XXVIII. 1. 1975 p. 127-136 House fly larvae as protein source from pig manure By L. PAPP (Received 10 November, 1974) Abstract: Experiments were carried out to judge the possible advantages of the processing of pig manure by house fly larvae and the limits of this method. Pro­duction yield was slightly above 8 % being close to the theoretical 10 % maximum On the basis of the results obtained the economicalness cannot be unequivocally decided, still the trial of our method is suggested under conditions of a small­scale agricultural plant. Some ecological data and some weight data on the pha­ses of ontogeny are also given. In our large agricultural concerns a grave problem is the elimination, destruction or consumption of the great quantity of manure; this had long been a task to solve. VOGT and BÖHME (1972) gave an excellent survey of manure utilization, among the possibili­ties offered the rearing of fly larvae on great quantities of various manures is discus­sed with a view to obtain pupae of high protein content which in turn are used as animal fodder. LINDNER (1919) suggested that perhaps fly larvae would be suitable to consu­me human waste in order to obtain feedstuff with good protein and fat content. Recently, American authors proved the high foraging value of house fly pupae (CALVERT et al. , 1969a, TEOTIA, MILLER, 1970b), and carried out experiments with house fly (Musca domestica L.) larvae to gain from the huge quantities of scarcely manageable chicken manure of high water-content a comparatively easily handled matter of granular' struc­ture with low water-content yet suitable for fertilization besides the mass of flypupae of high protein content (CALVERT et al. 1969b, 1970, MILLER, 1969, MILLER, SHAW, 1969, TEOTIA, MILLER, 1970a). The experiments has advanced so far that the method elaborated is ready for trial on a large scale .
