“…Changes in Tribolium can be explained by a deterioration of fitness in the pure + + cultures, rather than by an improvement in the Tribolium and housefly strains were chosen which from previous experiments were known to lack initial genetic facilitation, to permit an increase in facilitation to develop. Thus competition in Musca was between OL and bwb rather than OL and ge to avoid the known genetic facilitation of the latter (Bhalla and Sokal, 1964;Bryant, 1969). Tribolium mixtures in which bb was rare were similarly eschewed (Sokal and Karten, 1965).…”

“…Lewontin (1955), Lewontin and Matsuo (1963), Sokal and Huber (1963), Sokal and Karten (1965), Sokal and Sullivan (1963), Sullivan and Sokal (1965), and Bhalla and Sokal (1964) provide evidence for Drosophila, Tribolium and Musca. Decreased overlap in environmental requirements may be achieved by preferential utilisation of fine differences in the environment by different genotypes, or indirectly by the life processes of one competitor beneficially affecting the other, e.g.…”

“…through the enhancement of the substrate by desirable metabolites (Weisbrot, 1966;Bryant, 1969). The converse response to increased competition between species or strains may be reduced fitness of one or both competitors (genetic disoperation, Bhalla and Sokal, 1964).…”

These habits in combination with the house fly's capacity for disease transmission (Greenberg, 1973) have made it of medical and veterinary concern. The house fly has been implicated in the transmission and spread of a wide variety of human and animal pathogens (Sacca, 1964;Greenberg, 1973;.The house fly is an endopterygote insect and thus has complete metamorphosis accompanied by a pupal instar. The wings develop internally and the larval structure and habits differ from adults. After hatching from an egg, an individual passes through three larval instars, forms a sclerotized puparium and develops to the adult. At field temperatures (ca. 20-25° C), one day is required for egg hatch, 5-9 days for larval maturation, 6-11 days for adult development within the puparium and 3-6 days for a female to mature a batch of eggs (Larsen and Thomsen, 1940).Generation time is thus a temperature-dependent 14-27 dgys.Larvae mature and feed in decaying organic matter, animal excrement and spilled, fermenting animal feed. The growth of individuals occurs during the larval stage and is dependent upon the quality of larval breeding material. There is a strong negative correlation between adult size and larval density in the laboratory and field (Haupt and Busvine, 1968;. The number of eggs produced by females 2 is correlated with size and varies greatly within seasons (Black and Krafsur, 1956a).House flies are iteroparous, undergoing successive cycles of egg development and oviposition, the frequency of which is temperature dependent (Elvin and Krafsur, 1984). In temperate regions, house flies overwinter as small, slowly breeding colonies in livestock facilities et al., 1985). Stable age distributions were not detected . The Distribution of House Flies WorldwidePatton (1932, 1933, 1936, 1937) The subspecies domestica, vicinia and nebulo are distinguished on the basis of pigmentation and frons width (Sacca, 1964(Sacca, , 1957. Both characters were shown to be greatly influenced by temperature and crowding in the larval environment (Sacca, 1964).
