Specimens of the genus Phalangium Linnaeus, 1758 (Phalangiidae Latreille, 1802) are reported from northern Iraq and wereidentified as Phalangium punctipes (L. Koch, 1878). These represent the first record of both, genus and species, for the Iraqi Opiliones fau-na. The characteristic features of the species and illustrations of their habitat are pre...
New locality records for Mesobuthus mesopotamicus (Penther, 1912) are given from Iraq. The populations from southeastern
Turkey, earlier identified as M. mesopotamicus by Kovařík et al. (2022) are examined and compared with the specimens from type
locality of M. mesopotamicus. These populations are described as a new species, Mesobuthus faiki sp. n...
Background and objective: Early diagnosis and proper awareness of Breast Cancer conditions may aid in reducing the morbidity and mortality rate among women. The main goal of this study was to determine the awareness and knowledge levels of women undergraduate students at three public universities in Duhok province (Duhok, Zakho, and Polytechnic) on...
New data on the wolf spiders of Iraq are provided. Two species, Arctosa similis Schenkel, 1938 and Lycosa piochardi Simon, 1876, are reported from Iraq for the first time, and additional records and a redescription are provided for Evippa amitaii Armiach Steinpress, Alderweireldt, Cohen, Chipman & Gavish-Regev, 2021. Photographs of specimens of bot...
An updated and annotated checklist of the spiders of Iraq, currently comprising 104 species in 75 genera and 29 families is presented, including six endemic and four subendemic species. Twenty-three records are considered misidentifications and therefore omitted from the checklist. Where possible, the misidentified records are attributed to other s...
This study gives the first record of the scorpion species Orthochirus mesopotamicus (Birula, 1918) from the Al-Muthanna Province, Iraq. This is the first scorpion record from the Al-Muthanna Province that has been given until now. The scorpion sample was collected in the Al-Warka area of Al-Muthanna Province. In the current investigation, illustrat...
Background:
Annually, thousands of scorpion stings and rare mortalities are recorded in the Kurdistan Region of Iraq. In the present study, we prepared a checklist for the geographical distribution of scorpion fauna composition, new localities data, and scorpion sting profile for the years 2019-2020 in the region.
Methods:
Random field surveys f...
Spider
Five describe spider funna in Iraq
The Iraqi spider fauna includes several dozens of species described and reported mostly by local researchers but still
there are considerable sampling gaps. For the first time in Iraq, Agelena orientalis C. L. Koch 1837 (Agelenidae), Oxyopes globifer
Simon, 1876 (Oxyopidae), and Thanatus formicinus (Clerck, 1757) (Philodromidae) are recorded. In ad...
Abstract. The knowledge of the scorpion fauna of Iraq and its geographical distribution is limited. Our review reveals the presence in this country of 19 species belonging to 13 genera and five families: Buthidae, Euscorpiidae, Hemiscorpiidae, Iuridae and Scorpionidae. Buthidae is, with nine genera and 15 species, the richest and the most diverse f...

Information regarding scorpion diversity and their envenoming within Iraq in general, and the Northern Iraq in particular, is limited. The number and distribution of scorpion sting cases and some details of the scorpion fauna of Zakho province were reported for the first time in this study. Overall, 2675 scorpion sting cases were reported between 2...
PhTX IC 50 µм (-100mV) PhTX-343 16.6 PhTX-12 0.93 Muscle-nAChRs
Philanthotoxin-433 (PhTX-433) is an active component of the venom from the Egyptian digger wasp, Philanthus triangulum. PhTX-433 non-selectively inhibits several excitatory ligand-gated ion channels, and we recently showed that its synthetic analogue, PhTX-343, exhibits strong selectivity for neuronal over muscle-type nicotinic acetylcholine recept...
Insect toxins comprise a diverse array of chemicals ranging from small molecules, polyamines and peptide toxins. Many target nervous system and neuromuscular ion channels and so rapidly affect the behaviour of animals to which the toxin is applied or injected. Other modes of action have also been identified. Wasps, bees, flies, beetles and ants gen...
Knowledge regarding the smoking prevalence among the Kurdistan general population is not clear, at least for males. Here in the Kurdistan Youth Smoking Survey and Behaviours (KYSS&B) we tried to further expand our knowledge about the smoking profile of school students across Kurdistan. Five hundred students from four Zakho male basic schools were t...
Philanthotoxin-433 (PhTX-433) is an active component of the venom from the Egyptian digger wasp, Philanthus triangulum. PhTX-433 inhibits several excitatory ligand-gated ion channels, and to improve selectivity two synthetic analogues, PhTX-343 and PhTX-12, were developed. Previous work showed a 22-fold selectivity of PhTX-12 over PhTX-343 for embr...
Philanthotoxin-433 (PhTX-433) is an active component of the Egyptian solitary digger wasp, Philanthus triangulum, venom which non-selectively inhibits several excitatory ion channels. With the aim of improving potency and selectivity, several synthetic analogues were developed based on the single or multiple modifications in the hydrophilic polyami...
Neuronal nicotinic acetylcholine receptors (nAChRs) are excitatory ion channels, which have wide subtype diversity due to the many possible subunit combinations, some heteromeric, others homomeric. Each subunit is composed of a large N-terminal segment containing the ACh binding site and four membrane-spanning segments named M1-M4. The pore lumen i...
