The complete DNA sequence of the mtDNA cytochrome oxidase II gene from house fly, Musca domestica, face fly, Musca autumnalis, stable fly, Stomoxys calcitrans, horn fly, Haematobia irritans, and black garbage fly, Hydrotaea aenescens, are reported. The nucleotide sequence codes for a 229 amino acid peptide. The COII sequence is A + T rich (74.1%), with up to 12.3% nucleotide and 8.4% amino acid...

Species composition, seasonality and distribution of immature fly populations on a southern Queensland feedlot during 2001-2003 were determined. Similar data were collected on feedlots in central New South Wales and central Queensland. The fly species recovered in the highest numbers were Musca domestica L. (Diptera: Muscidae), Stomoxys calcitrans L. (Diptera: Muscidae) and Physiphora clausa Ma...

Several species of the family Apiaceae are aromatic herbs that produce essential oils usable on an industrial scale for pharmaceutical, cosmetic, and food purposes. In particular, some oils, such as green insecticides example, may replace synthetic insecticides, keeping most their efficacy avoiding environmental pollution or human poisoning. present study, we explored insecticidal potential Rid...

Under constant conditions, locomotor activity in about 50% of 63 adult Musca domestica continued to be rhythmic after bilateral severance of optic tracts or bilateral lobectomy. Apparently, the optic lobes of Musca do not contain the oscillator for rhythmic control of locomotor activity as has been proposed for other insects. In 20% of the individuals, several circadian components of activity r...

Hydrocarbons were the major lipid class extracted by hexane from the vitelline membrane surface of dechorionated eggs of the house fly, Musca domestica, the New World screwworm, Cochliomyia hominivorax, the secondary screwworm, Cochliomyia macellaria, the green bottle fly, Phaenicia sericata, the sheep blow fly, Lucilia cuprina and the Mexican fruit fly, Anastrepha ludens. The length of time th...

Adult muscoid flies collected from three dairies and eight commercial poultry ranches in San Bernardino County were tested for Salmonella enteritidis. Of the total 2,686 flies tested, 92.3% were Musca domestica, 5.5% Fannia canicularis, 1.9% Ophyra leucostoma, 0.2% Phaenicia sericata, and <0.1% Muscina stabulans. Whereas flies at the dairies belonged exclusively to M. domestica, faunal composit...

The house fly, Musca domestica, is a very significant pest due to transmitting of various human and animal pathogenic diseases. In a response to environmental threats of chemical insecticides, toxic and biochemical effects of a relatively new plant extracts of willow (Salix aegyptiaca L.) and chasteberry (Vitex agnus-castus L.) comparing with NeemAzal T/S were studied on 3 larval instar of M. d...

Yolk spheres present in mature invertebrate oocytes are composed of yolk proteins and proteolytic enzymes. In the fly Musca domestica, yolk proteins are degraded during embryogenesis by a cathepsin-like proteinase that is stored as a zymogen. An acid phosphatase is also active in the yolk spheres during Musca embryogenesis. In this paper we show that procathepsin and acid phosphatase are initia...

The ultrastructural superficial changes in third instar house fly (Musca domestica) and blow fly (Chrysomya megacephala) induced by eucalyptol oil were observed using scanning electron microscopy. Dipped in 0.902 g/ml eucalyptol for 30 sec, the larvae integument of both species showed significant aberrant appearance of the body surface, particularly swelling integument, bleb formation, partial ...
