background:  the residual effect of triflumuron and pyriproxyfen on musca domestica l larval stages was studied in the laboratory. methods : both igrs at varying concentrations ranging between 0.5 to 2.5 mg/l were placed inside beakers with mice chow and vitamin b complex and water as food for the 1 st , 2 nd and 3 rd instars m.domestica larvae. results: both igrs inhibit m. domestica adult eme...

The results of a photometric programme aiming to investigate the hypothesis of a physical association between the Southern Coalsack and the Chamaeleon-Musca dark clouds are presented. The analysis is based upon uvbyβ photometry for 1017 stars selected from the Smithsonian Astrophysical Observatory star catalog to cover these clouds and the connecting area defined by the galactic coordinates: 30...

Thriving, permanent colonies of Musca xanthomelas and later of Musca nevilli were successfully established. However, because of the low reproduction potential of Musca lusoria a small colony only was kept for a limited period until life-cycle studies were completed. Larvae were reared on fresh dung from cattle fed lucerne, while in general adults were fed 0.3% citrated ox-blood, whole milk powd...

background: medicinal plant extracts such as those obtained from salvia species have a wide variety of chemical compounds in their essential oils. the repellency of a number of essential oils including those from the labiates like salvia against several insect species including the common house flies is reported. objective: the aim of this investigation was to find out the excito-repellency eff...

Fluralaner (Bravecto) is a recently marketed isoxazoline ectoparasiticide. This compound potently inhibits GABA-gated chloride channels (GABACls) and less potently glutamate-gated chloride channels (GluCls) in insects. The mechanism underlying this selectivity is unknown. Therefore, we sought to identify the amino acid residues causing the low potency of fluralaner toward GluCls. We examined th...

Musca domestica salivary gland hypertrophy virus (MdSGHV) is a disease that enlarges the salivary glands of Musca domestica (the common house fly), as well as causes infertility in female house flies. An infected female fly will no longer produce or lay eggs and will refuse a male’s mating attempts. Collaborating with the University of Florida’s Entomology and Nematology Department, we have hyp...

It is shown that a total of eight pre-existing genus-group names in Diptera were "borrowed" and deliberately given new identities in the systematic works of J.C. Fabricius: Bibio Fabricius, 1775, Ceria Fabricius, 1794, Hirtea Fabricius, 1798, Mulio Fabricius, 1798, Scatophaga Fabricius, 1805, Sicus Fabricius, 1798, Thereva Fabricius, 1798 and Voluccella Fabricius, 1794. These names are reviewed...

This study was carried out to determine the role of non-biting cyclorrhaphan flies as carriers of human intestinal parasites at Woreta, northwestern Ethiopia. In total, 6530 flies were collected from four breeding sites and then examined for human intestinal parasites, mainly using the formol-ether concentration method. Fly species identified were Musca domestica (32.9%), Chrysomya rufifacies (...

Diarrhea is an endemic disease in Indonesia and a potential Extraordinary Events (KLB) which are often accompanied by death. Based on data diarrhea cases at the Narmada Community Health Center 2017 there were 1.679 of from 11 villages District. One causes these presence house flies as vector carrying disease. The purpose this study was to determine bacterial culture streak method for inventory ...

In Drosophila, the clock gene period (per), is an integral component of the circadian clock and acts via a negative autoregulatory feedback loop. Comparative analyses of per genes in insects and mammals have revealed that they may function in similar ways. However in the giant silkmoth, Antheraea pernyi, per expression and that of the partner gene, tim, is not consistent with the negative feedb...
