Hedya tritofa, new species, is described and illustrated based on eleven males and five females collected in northern Iran (Gilan, Mazandaran, and Golestan provinces). Morphology and diagnostic characters of Hedya Hübner, 1825, Metendothenia Diakonoff, 1973, the Olethreutes group of genera, and the Neopotamia group of genera are discussed. We propose the resurrection of the combinations Hedya atropunctana (Zetterstedt, 1840), revised status, and H. separatana (Kearfott, 1907), revised status, and the new combination H. inouei (Kawabe, 1987).

Twenty-seven species of the two tribes Platyptiliini and Exelastini are listed. The genus Exelastis and the following species are reported from Iran for the first time: Platyptilia calodactyla ([Denis & Schiffermüller]), P. nemoralis Zeller, P. farfarellus Zeller, Gillmeria armeniaca (Zagulajev), G. pallidactyla (Haworth), G. ochrodactyla ([Denis & Schiffermüller]), Stenoptilia zophodactylus (Duponchel), S. lucasi Arenberger, Paraplatyptilia metzneri (Zeller), M. asiatica (Rebel) and Exelastis atomosa (Walsingham).

Two species of hornets are present in Iran: Vespa orientalis Linnaeus, 1771, has a widespread distribution in most parts of Iran, except for the Caspian coast in northern Iran, but V. crabro Linnaeus, 1758, is present only on the Caspian coast. The ambiguity regarding these two species in Iran, their distribution patterns, diagnoses and agricultural aspects are discussed. © Kasparek Verlag, Heidelberg. Source

A multiclass and multi-residue method was optimized and validated for analysis of 19 pesticides of 16 chemical classes in greenhouse cucumber and tomato followed by high performance liquid chromatography-tandem mass spectrometry (HPLC-MS/MS). In this study a dispersive liquid-liquid microextraction (DLLME) technique was applied for extraction and pre-concentration of pesticide residues from QuEChERS (quick, easy, cheap, effective, rugged and safe) extracts. The DLLME method was carried out using carbon tetrachloride as the extraction solvent and QuEChERS extract as the dispersive solvent. The main parameters affecting DLLME efficiency including the type and volume of extraction solvent and the volume of dispersive solvent and salt addition were optimized for the proposed method. To validate this developed method, recovery studies were carried out at two concentration levels, yielding mean recovery rates in the range of 86 to 104% with relative standard deviations below 12%. Good linearity and precision, with relative standard deviations generally below 10%, were obtained for all 19 pesticides. The method limits of detection (LOD) between 3.4 and 10.4 μg kg-1 and method limits of quantification (LOQ) in the range of 11.2-34.5 μg kg-1 were obtained for the proposed method. Recovery rates and method LODs and LOQs of the validated method were compared with those of the routine QuEChERS method and results indicated the efficiency of the proposed method for routine analysis of 19 pesticide residues in cucumber and tomato. © 2013 The Royal Society of Chemistry.

Bacillus thuringiensis bioinsecticide has been widely used on crops worldwide to replace chemical pesticides. B. thuringiensis production by solid-state fermentation requires less capital investment and modest technical skills. The method is often considered unsuitable for growth of aerobic organisms. However, optimization of Bt production using solid-state fermentation can effectively contribute to promote use of this bacterium in insect pest management programs. Research into suitable nutrient concentrations of different media and characteristics of bacterial growth on these has enabled use of several agricultural or industrial by-products for mass production of several Bt strains. These materials include wheat bran, rice bran, rice crumb, and remaining barley from feeding of Sitotroga serealella. Wheat bran was the best of media for production of B. thuringiensis. ©JBiopest.
