Host plant use by nymphs and adults of the nonnative speciesHalyomorpha halys (Stål) (Hemiptera: Pentatomidae) was investigated proximal to the location of its introduction, Allentown, PA. The seasonality ofH. halys in the United States had not been thoroughly studied before this work. It is reported to have 300 host plants in its native range that could make control and identiÞcation of small ...

an investigation was carried out in ahar district, (a new focus of visceral leishmaniasis), eastern azerbaijan, north-west of iran in order to determine the vector(s) of the disease, during the summer of 2003 sand-flies were collected using sticky papers, cdc light traps and aspirators. all of the collected sand-flies were dissected in a drop of normal saline for surveying of promastigotes. hea...

following annual report of new cases of cutaneous leishmaniasis from different areas of kuhpayeh district, esfahan county, an investigation was carried out on some ecological aspects of phlebotomine sand flies during 2000-2002. sand flies were collected biweekly from outdoor and indoor resting places with the aid of 30 sticky traps from the be ginning to the end of the active season. female san...

Some myotoxic or neurotoxic PLA2s (phospholipases A2) from pit viper venoms contain characteristic N6 substitutions. Our survey of the venoms of more than ten pit viper genera revealed that N6-PLA2s exist only in limited Asian pit vipers of two genera, Protobothrops and Gloydius, and exist as either monomers or the basic subunits of heterodimers in some New World pit vipers. For the newly ident...

OBJECTIVES This study was undertaken to isolate a fibrinolytic enzyme from the snake venom of Gloydius blomhoffii siniticus and to investigate its enzymatic characteristics and hemorrhagic activity as a potential pharmacopuncture agent. METHODS The fibrinolytic enzyme was isolated by using chromatography, sodium dodecyl sulfate-polyacrylamide gel electrophoresis, and fibrin plate assay. The c...

The Parsley frog is represented by single species from Anatolia which called Pelodytes caucasicus. This categorized as a near threatened in the conservation list and has very limited distribution along North East Black Sea its populations have been poorly studied. In this study, we analyzed morphological variation of 59 specimens different localities (Artvin; Karagöl, Rize; Çat Trabzon; Hıdırne...

Brown marmorated stink bug, Halyomorpha halys (Stål), injury to late-season apple cultivars was measured at harvest in 2011 and 2012 in commercial orchards in four mid-Atlantic states. In each orchard block, a border zone (adjacent to woods), an interior zone (near orchard center), and an intermediate zone (between border and interior zones) comprised 1-3 tree rows per zone, depending on block ...

Agkistrodon halys is one of several dangerous snake species in Iran. Among the most important signs and symptoms in patients envenomated by this snake is disseminated intravascular coagulation. A thrombin-like enzyme, called AH143, was isolated from Agkistrodon halys venom by gel filtration on a Sephadex G-50 column, ion-exchange chromatography on a DEAE-Sepharose and high performance liquid ch...
