Body composition and fatty acid profile of the body tissue of Caspian kutum (Rutilus frisii kutum) fish larvae were determined from fertilized egg to 50 days post hatching (dph). Feeding with rotifer started from day 3 to day 7 thereafter they were fed with dry food until the end of the experiment. The changes observed in lipid content and the decrease in lipid levels during larval ontogeny ref...

  Khark and Kharko Islands are located at far northern point of fringing coral reefs in the Iranian coast of the Persian Gulf. These coralline are the habitats of the wildlife refuge with total area of 2400ha and located in the territory of Bushehr province. The present study was carried out from July 2006 to June 2007 over 12 stations. Sampling was conducted obliquely from bottom using Bongo-n...

Tomato leafminer, Tuta absoluta Meyrick (Lepidoptera: Gelechiidae) is one of the most destructive pests of tomato in many parts of the world including Iran. The toxicity of emamectin benzoate alone and combined with acetamiprid, eforia (thiamethoxam + lambda-cyhalotrin) and hexaflumuron was evaluated against 2nd instar larvae of Tuta absoluta (Meyrick) under 25 ± 1 °C, the relative humidity of ...

Propolis is a substance derived from antimicrobial plant resins that honey bees use in the construction of their nests. Propolis use in the hive is an important component of honey bee social immunity and confers a number of positive physiological benefits to bees. The benefits that bees derive from resins are mostly due to their antimicrobial properties, but it is unknown how the diversity of a...

The underwater silk of an aquatic casemaking caddisfly larvae (Hesperophylax occidentalis) is viscoelastic, and displays distinct yield behaviour, large strain cycle hysteresis and near complete recovery of its initial strength and stiffness when unloaded. Yield followed by a stress plateau has been attributed to sequential rupture of serial Ca(2+)-cross-linked phosphoserine (pS) β-domains. Spo...

Although Professor Maden’s article was only 100 words long, it contained some profound and, I think, unfair and unsubstantiated, statements. Where is the evidence that patients with severe antisocial personality disorders who do not want to be treated, like many of those detained in the dangerous and severe personality disorder (DSPD) unit at Broadmoor Hospital, where Professor Maden is the cli...

background: the american foulbrood disease (afb), caused by paenibacillus larvae subsp. larvae, is one of the main plagues affecting honey bee (apis mellifera l.) colonies, and it has a high negative impact on beekeepers worldwide. objectives: the aim of this research was to describe the evidence of paenibacillus larvae larvae contamination of honey bee colonies, in the east azerbaijan province...

this paper reviews the research on taxonomy of the trombidioidea in iran, with an updated checklist of 32 species (+5 undetermined species) belonging to five families and 22 genera. among them, 27 species (+1 undetermined species) are reported based on larvae only, three undetermined species based on adults only, and six species based on both larval and post-larval stages. also, 14 species (+3 ...
