This report contains a description of the karyotypes of Musca sorbens Wied., Musca vetustissima Walker, several strains of the subspecies domestica and the subspecies curviforceps and calleva of Musca domestica L., Musca autumnalis De G., Muscina.stabulans Fall., Orthellia nudissima (Loew), Ophyra leucostoma Wied., Phaonia basalis Fabr., and Phaonia variegata Fabr. Species M. stabulans, O. nudissima, and P. variegata have 2n = 10 chromosomes and all the others 2n = 12, but some specimens of M. domestica curviforceps have only 11. The sex chromosomes of M. autumnalis and O. leucostoma are very small and this pair has apparently been lost in the 10-chromosome species. It is suggested that species having 10-chromosome karyotypes may have originated independently in different subfamilies and genera of the Muscidae.

Differential Dna Replication

The karyotype of Musca domestica L. ocra strain, consists of the sex chromosomes and five autosomal pairs. The heteromorphic sex chromosomes are heterochromatic and mitotically unpaired, whereas the autosomes are euchromatic and mitotically paired. All autosomal pairs and both X and Y chromosomes are cytologically recognizable.The relative labelling rate, R (in terms of the number of grains counted per 100 labelled metaphases per μ of chromosome length) for the sex chromosomes and for each autosomal pair was followed from 1.5 hours to 8 hours after H3TdR injection. The pattern of labelling rate was similar for the different autosomal pairs in the XX cells but this pattern for the autosomal pairs in the XY cells, though also similar for the different pairs, differed appreciably from that found in the XX cells. The pattern of the labelling rate for the X chromosomes was similar in the XX and XY cells. Also the pattern of labelling rate for the X and Y chromosomes was similar during the final part of the replication period. The two X chromosomes in the XX cells and the X and Y chromosomes in the XY cells completed labelling later than the autosomes.

AbstractFive species of Trichomalopsis Crawford associated with Haematobia irritans (L.) (horn fly), Musca domestica L. (house fly), Musca autumnalis DeGeer (face fly), and Stomoxys calcitrans (L.) (stable fly) in North America are reviewed. The species Trichomalopsis americana (Gahan), Trichomalopsis dubia (Ashmead), Trichomalopsis sarcophagae (Gahan), Trichomalopsis tachinae (Gahan), and Trichomalopsis viridescens (Walsh) are described, keyed, and differentiated from other recognized North American species. Lectotypes are designated for T. dubia, T. sarcophagae, and T. tachinae. Distribution and host associations are recorded for the species. Trichomalopsis americana and T. viridescens are newly recorded as parasitoids of M. domestica; T. dubia and T. sarcophagae are also newly recorded as parasitoids of Hypoderma lineatum (Villers) (common cattle grub) and Hypoderma bovis (L.) (northern cattle grub), respectively. Some previously published host associations and parasitoid identifications are corrected based on examination of voucher specimens. The known biology of each species is reviewed. The presence of Trichomalopsis albipilosa (Gahan) in North America is considered to be erroneous based on a misidentification of T. americana.

Musca Autumnalis

Musca domestica L., the house fly, has hitherto been the only species of the genus definitely known to occur in North America. West (1951) wrote: “This paucity of species in the New World is somewhat strange…it would not be surprising if one or more additional representatives of the genus Musca should sooner or later put in their appearance on the American scene.” An authentic record of a second species, M. autumnalis Deg. [=M. corvina Fab.], is therefore of considerable interest.
