Objective: To carry out the distribution survey of hard ticks of livestock in Boeen Zahra and Takistan counties of Qazvin province from April 2010 to September 2010. Methods:Nearly about 2 638 sheep, 461 goats and 318 cattle of 38 herds in different geographical areas were searched for tick infestation. Results:The species compositions collected from the livestock of Boeen Zahra and Takistan were Haemaphysalis concinna (0.63%), Haemaphysalis sulcata (12.66%), Hyalomma anatolicum (3.80%), Hyalomma asiaticum (3.16%), Hyalomma detritum (5.70%), Hyalomma dromedarii (28.48%), Hyalomma marginatum (13.29%), Hyalomma schulzei (1.89%), Rhipicephalus bursa (3.16%) and Rhipicephalus sanguineus (3.16%), and for Takistan’s livestock were Hyalomma dromedarii (9.86%), Hyalomma marginatum (13.29%), Hyalomma schulzei (1.89%) and Rhipicephalus sanguineus (3.16%), respectively. Hard ticks compositions in different topographic areas were different. Hyalomma species had the most prevalence in the areas. Conclusions:The veterinary and public health investigation of the above species should be taken.

Objective: To study agents of animal wound myiasis in various geographical districts of Fars province. Methods: This study has been done in Fars province, located in the southern part of Iran. Sums of 10 358 domestic animals have been visited from April 2011 to March 2012. The infected wounds in any parts of animal body were sampled by means of forceps. Results: About 61% of all animal wound myiasis were caused by larvae of Wohlfahrtia magnifica. The most wound myiasis cases due to this species occurred in central part of Fars province. There wasn't any significant difference between sheep and goat in infestation with myiasis (P>0.05). The infestation rate of myiasis in cattle community was 0.86%. Conclusions: The infestation rate of livestock was lower than other works in Iran and some other countries like Saudi Arabia. Chrysomya bezziana has been mentioned as main myiasis agent in Iran. But in this study it cleared that similarly to some European countries, the common animal myiasis agent in Iran is Wohlfahrtia magnifica. Introducing new species as principal agent for myiasis can help public health and animal husbandry policy makers to prepare sufficient and effective control and/or preventive measures for this disease.

Objective: To establish a spatial geo-database for scorpions in Iran, and to identify the suitable ecological niches for the most dangerous scorpion species under different climate change scenarios. Methods: The spatial distribution of six poisonous scorpion species of Iran were modeled: Hemiscorpius lepturus, Androctonus crassicauda, Mesobuthus eupeus, Hottentotta saulcyi, Hottentotta zagrosensis, and Odontobuthus (O.) doriae, under RCP2.6 and RCP8.5 climate change scenarios. The MaxEnt ecological niche model was used to predict climate suitability for these scorpion species in the 2030s and 2050s, and the data were compared with environmental suitability under the current bioclimatic data. Results: A total of 73 species and subspecies of scorpions belonging to 19 genera in Iran were recorded. Khuzestan Province has the highest species diversity with 34 species and subspecies. The most poisonous scorpion species of Iran are scattered in the semi-arid climates, at an altitudinal range between 11 m and 2 954 m above sea level. It is projected that O. doriae, Androctonus crassicauda and Mesobuthus eupeus species would be widely distributed in most parts of the country, whereas the most suitable ecological niches for the other species would be limited to the west and/or southwestern part of Iran. Conclusions: Although the environmental suitability for all the species would change under the two climate change scenarios, the change would be more significant for O. doriae under RCP8.5 in the 2050s. These findings can be used as basis for future studies in the areas with the highest environmental suitability for the most dangerous scorpion species to fill the gaps in the ecology of scorpion species in these areas.
