based on specimens collected from east azerbaijan province during 2009-2012, five genera and nine species of the family scathophagidae are recognized. eight species including: cordilura rufipes (meigen, 1826), gimnomera montana ozerov et krivosheina, 2013, norellisoma spinimana (fallén, 1819), parallelomma albipes (fallén, 1819), scathophaga kaszabi (šifner, 1975), scathophaga lutaria (fabriciu...
Horse and cow dung were tested as substrates for oviposition by the stable fly Stomoxys calcitrans (L) (Diptera: Muscidae) in laboratory cages. Odour alone from either horse or cow dung was sufficient to attract flies for oviposition. This was confirmed in wind tunnel experiments, where both horse and cow dung were shown to attract gravid stable flies. However, when S. calcitrans was offered a ...
Veterinary pharmaceuticals excreted in the dung of treated livestock can have strong non-target effects on the dung organism community. We report results of ecotoxicological tests with ivermectin for 21 species of temperate (Europe, North America) and tropical (Asia, Central America) black scavenger flies (Diptera: Sepsidae), using standardized methods developed previously for the yellow dung f...
Aging of bovine dung for 3-5 years under refrigeration resulted in smaller sizes of horn fly, Haematobia irritans (L.), pupae. Growth of horn fly larvae in mixtures of aged and fresh dung resulted in production of larvae and pupae stunted in proportion to the relative amount of aged dung. Reduction of size of pupae produced in aged dung was because of nutrient limitation, which was partially re...
Under experimental conditions an African face fly (Musca xanthomelas) preferred to feed on cattle dung when provided with a choice of 3 different meals namely sucrose, cattle dung and blood. Flies starved overnight fed well on the eyes of cattle and rabbits, but were reluctant to feed again within 2 h after being allowed to feed on cell culture medium or on the eyes of wildebeest, and when they...
The coexistence of ecologically similar species (i.e. species utilizing the same resource) is a major topic in ecology. Communities are assembled either through the biotic interactions of ecologically similar species, e.g. competition, or by the abiotic separation of species along gradients of environmental conditions. Here, we investigated the temporal segregation, succession and seasonality o...
The coprophagous fauna associated with the mammals of Africa plays an important role in the recycling of nutrients and in the destruction of the habitat of many dung breeding flies [1], The failure of this process has been recorded in Australia where cattle were introduced without the associated insect fauna, resulting in the deteriora tion of the pastures [2] and the uncontrolled increase of ...
Pyrethroid insecticides are widely used to control ectoparasites of livestock, particularly ticks and biting flies. Their use in African livestock systems is increasing, driven by the need to increase productivity and local food security. However, insecticide residues present in the dung after treatment are toxic to dung-inhabiting insects. In a semiarid agricultural habitat in Botswana, dung b...
11 Evidence for selective disadvantages of large body size remains scarce in general. Previous 12 phenomenological studies of the yellow dung fly Scathophaga stercoraria have demonstrated 13 strong positive sexual and fecundity selection on male and female size. Nevertheless, the body 14 size of flies from a Swiss study population has declined by almost 10% from 1993 to 2009. 15 Given substanti...
