Co-evolution between developmental regulatory elements is an important mechanism of evolution. This work compares the hunchback-bicoid interaction in the housefly Musca domestica with Drosophila melanogaster. The Musca HUNCHBACK protein is 66% conserved and partially rescues a hunchback mutant, yet the BICOID-dependent promoter (P2) of Musca hunchback is unexpectedly diverged from D. melanogast...

Many non-biting muscids (filth flies) are characterised by the habit of visiting manure or rotting organic material to feed and/or oviposit. As these flies also often have close associations with human beings, as well as human habitations and domestic animals, they are potentially both a nuisance and a contributory factor in the transmission of diseases. The authors examine the biology, economi...

Comparative measurements are presented of the sequence complexity of the RNA stored in the eggs of two dipteran flies, Musca domestica and Drosophila melanogaster. The genome of Musca is about five times the size of the Drosophila genome and contains about 3.6 times as much single-copy sequence. As shown earlier, the interspersion of repetitive and single-copy sequence is of the short-period fo...

House flies (Musca domestica L.) are major disease spreading vectors in variety of both outdoor and indoor conditions, especially near livestock farms domestic waste disposal landfills. Presently no effective choices available for the control house as these flies’ have developed resistance to all synthetic pesticides. Pheromone traps play a vital role fly management conditions. The present stud...

NEVILL, E. M., 1975 Preliminary report on the transmission of Parafi/aria bovicola in South Africa. Onderstepoort J. vet. Res. 42 (1), 41-48 (1975) The filarial worm Parafi/aria bovico/a causes streaks of blood on the skins of live cattle and slimy bruise-like lesions on the subcutaneous surfaces of their carcases. To determine the vectors of this worm a field survey was conducted in November 1...

A total of 20 375 flies collected off cattle on 12 farms over 36 months were identified and examined for 3rd stage P. bovicola. The 3 vector species accounted for 64.1% of the flies collected and were the only fly species found to be infected. Musca lusoria was clearly the dominant vector fly, although large numbers of Musca sp. A appeared regularly between February and April each year. This ph...

Sex-lethal (Sxl) is the master switch gene for somatic sex determination in Drosophila melanogaster. In XX animals, Sxl becomes activated and imposes female development; in X(Y) animals, Sxl remains inactive and male development ensues. A switch gene for sex determination, called F, has also been identified in the housefly, Musca domestica. An active F dictates female development, while male de...

background: metarhizium anisopliae strain iran 437c is one of the most virulent fungal isolates against house fly, musca domestica . the objective of this study was to determine the interaction of this isolate with sublethal doses of spino­sad against housefly. methods: in adult bioassay, conidia of entomopathogenic fungus were applied as inoculated bait at 10 5 and 10 7 spore per gram and spin...

Kurşun, ağır metaller arasında oldukça toksik bileşiklerden biridir, organizmalar ve ekosistemler üzerinde ciddi problemlere yol açarlar. Bu çalışmanın amacı kurşunun adli açıdan önemli bir sinek olan musca domestica 'nın (diptera: muscidae) bazı gelişimsel parametreleri üzerindeki etkilerini incelemektir. Mevcut çalışmada 30 adet larvası dört farklı kurşun konsantrasyonuna maruz bırakılmış bes...
