The olfactory system of sexually immature 1-day-old flies is already functional. No clear differences exist between the responses of their olfactory cells and those of sexually mature flies to amylacetate, S-methylphenol, 2-pentanone and R(+)-limonene. However, the sensitivity to 1-octen-3-ol is lower in young flies than in old flies.

Chromatin condensation in the aging housefly
Experimental Gerontology, 1984Abstract Computer analysis of digitized images of Feulgen-stained optic lobe and Malpighian tubule nuclei from the adult male housefly has shown significant age-related changes in several image features. These features relate to the amount and spatial distribution of a high and medium density chromatin component (HDC, MDC).

Disrupting housefly gene reverses sex
Science, 2017Sex Determination Sex comes in many forms, even when considered at the molecular level. In different animals, the chromosomes and specific genes that function in sex determination vary widely. As a case in point, the familiar housefly displays a highly variable sex determination system.

Acetylcholinesterase isozymes from the housefly brain
Biochimica et Biophysica Acta (BBA) - Enzymology, 1970Abstract 1. 1. Cholinesterase activity in insect head extracts was investigated by disc electrophoresis followed by spectrophotometric analysis. The supernatant of 100 000 × g , 1 h, revealed the presence of four isozymes in the housefly, two in the American cockroach and only one in the southern army worm. 2. 2.

The sterol esters of housefly eggs
Comparative Biochemistry and Physiology, 1963Abstract 1. 1. The free sterols and sterol esters from adult female houseflies and eggs were separated by column chromatography. The sterol ester fraction accounted for about 41 per cent of the total sterol from housefly eggs but only about 8·4 per cent in the female flies. 2. 2.

Their habit of breeding in putrefying matter has led many of the higher flies into an interesting and sometimes important association with various animals (wild and domesticated) and with man. Although some maggots feed on living plants, it is possible that the original breeding material of the group was decaying vegetation, which is still the normal ...

Somatic crossing-over in the housefly
Molecular and General Genetics MGG, 1971X-rays were found to produce genetically marked cells and cell clones in heterozygous larvae of Musca domestica. The results favor the conclusion that these marked clones originated by somatic crossing-over. The technique should prove useful in developmental analyses of the housefly.

Measurement of narcotic potency using houseflies
Annals of Applied Biology, 1966SUMMARYA method is described for the measurement of narcotic potencies of chemical compounds, using houseflies. Narcotic potency measurements give rise to statistical problems which differ from those encountered in toxicity determinations in so far as the narcotic process is reversible, and successive values of the number of affected insects in a group

The housefly interfacetal hair
Cell and Tissue Research, 1976The external and internal fine structure of the housefly interfacetal hair and its sensory dendrite was studied with the scanning and transmission (high and low voltage) electron microscopes. The hair shaft contains no dendrites, and is usually situated within a socket on the lens surface.

The assessment of the current status and prospects for the control of houseflies is partly based on the literature, but primarily on 30 years of personal experience in housefly control in temperate Denmark and on visits to many parts of the world, including tropical and subtropical areas, where I observed and discussed control problems.
