Abstract Background Various bleaching agents are used in food industries among which some reacts to form alloxan. Therefore, the alloxan can indirectly enter a human body and thus an important aspects for studying its effect on development. In present study, of was studied climbing ability, pupation emergence flies. Fifty first instar larvae were introduced separately vials containing 0.001, 0....

We studied the efficiency and toxicity of new insecticide “GET Dry” (active ingredients alpha-cypermethrin imidacloprid). The target as acute residual impact was studied, when agent applied against tropic bed bugs (Cimex hemipterus), German cockroach (Blatella germanica), false stable flies (Musca domestica) larvae leather beetles (Attagenus smirnovi). demonstrated strong effect (about 100%), c...

Non-native plants are invading terrestrial ecosystems across the globe, yet little is known about how invasions impact carbon (C) cycling or how these impacts will be influenced by climate change. We quantified the effect of a non-native C4 grass invasion on soil C pools and fluxes in a Hawaiian tropical dry forest over 2 years in which annual precipitation was average (Year 1) and 60% higher t...

Fresh grass in the cow diet improves the rheological and nutritional properties of butter. However, the relationship between the proportion of fresh grass in the diet and these properties is still unknown. The objective of the study was to determine the relationship between the proportion of fresh grass in the diet and the properties of milk and butter. Four groups of 2 cows were fed 4 isoenerg...

abstract during growing seasons of years 2006 & 2007, a faunistic survey on syrphidae family(diptera) in agroecosystems of neyshabor region, khorasan-e-razavi province was carried out. in this study, 3 collection methods: yellow water trap, malaise trap and sweeping net were applied. the results showed a large difference between different collection methods. specimens of 14 species collected by...

an outbreak of zoonotic cutaneous leishmaniasis caused by leishmania major was identified in ghanavat rural district, qom province, central iran, during 1999-2001. among 1069 inhabitants examined in dec. 1999, 5.14% showed evidence of active lesions and 12.44% had scar indicative of past infection. the most highly infected age group was 5-9 years old for ulcers with a rate of 6.56%. the inciden...

visceral leishmaniasis due to leishmania infantum is endemic in many rural areas of iran. an investigation was carried out during april to november 2001 in ghahan rural district of qom province, in order to identify the phlebotomine sand fly fauna. 971 sand flies were totally collected from outdoor and indoor resting places by sticky traps. ten species of phle botomine sand flies including 8 sp...

The sand fly Phlebotomus papatasi Scopoli, 1786, the vector of Leishmania major Yakimoff et Schokhor, 1914, is found in desert areas where sugars are scarce but also in habitats that abound in sugar sources. The sand flies require sugar meals from plant sources for their energy requirements and to hydrolyze these complex sugars, they need a repertoire of glycosidases. We presumed that there are...

Most of the 400 million grass pollen-allergic patients worldwide are co-sensitized to several unrelated grass pollen allergens. Based on frequent co-sensitization patterns determined in 200 grass pollen-allergic patients, three recombinant hybrid molecules were developed by polymerase chain reaction-based mending of cDNAs coding for the major timothy grass pollen allergens (Phl p 1, Phl p 2, Ph...
