Abstract. Mansouri NJS, Akbarzadeh K, Jahanifard E, Vazirianzadeh B, Rafinejad J. 2021. Species diversity and abundance of scorpions in Ahvaz city, Southwest Iran. Biodiversitas 22: 763-768. Arthropods are one of the most important and diverse phyla of the animal kingdom. This phylum includes several classes of insects and arachnids, which are of medical and veterinary importance. Scorpions are at the top of the group of venomous arthropods in terms of having venomous bites and causing death. Scorpions live mainly in tropical and subtropical regions of the world and therefore have higher diversity and richness in these regions. This study aimed to investigate the biodiversity and abundance of scorpions in Ahvaz city, Khuzestan province, Iran. It has the highest species diversity and species richness in Iranian scorpions. Scorpions were collected from five regions in Ahvaz using various methods. In total 237 scorpions were collected and identified. They belonged to two families, seven genera and seven species: Mesobuthus eupeus (65%), Hemiscorpius lepturus (23.2%), Androctonus crassicauda (3.8%), Compsobuthus rugosulus (3.4%), Orthochirus zagrosensis (2.5%), Apistobuthus susanae (1.7%), Buthacus macrocentrus (0.4%). Except for H. lepturus (Hemiscorpiidae), other species belonged to the Buthidae family. That all of them were non-burrowing. M. eupeus was the dominant species diversity analysis indicated higher species richness and species diversity for summer (Margalef = 1.07; Shannon = 1.55). Logistic regression analysis showed that the variables of geographical location, humidity, and temperature had a significant relationship with the abundance of scorpion species, while height had no statistically significant.

Biodiversitas 24: 1467-1472. Species diversity of medically important necrophagous flies in Southwest Iran. Biodiversitas 24: 1467-1472. The insects are the most successful group in the phylum Arthropoda. Flies are among the most diverse group of insects and organisms. Flies can affect human health in many ways, such as the transmission of a wide range of pathogens and myiasis. Species diversity is the middle level of the hierarchical system of biodiversity. Flies, like other insects, are sensitive to biotic and abiotic factors, and their biodiversity will change under different climatic conditions. This study was performed in Ilam province, in southwest Iran. Two methods were used for collecting the flies, including bottle traps and insect nets. Fly collections were done monthly at each collection site for a year, and to identify the trapped flies, reliable identification keys were used. Calculation of fly species diversity indices was done based on the Shannon-Wiener index, species dominance based on the Simpson dominance index, species richness employing the Margalef's index, and evenness was performed based on the Evenness index. Different aspects of species diversity were calculated using PAST V.3 software. The dominance and abundance of necrophagous flies were higher in the south of the province. The highest evenness was related to the north of the province. A comparison of the diversity of necrophagous flies also indicated that the north of the province has a high species diversity. A significant and positive relationship between fly frequency and the temperature was seen. There was also a significant and negative relationship between the frequency of flies and humidity. The results of this study completed one of the research puzzles on the biodiversity of Iranian flies. The abundance and diversity of necrophagous flies were high in the Ilam province, especially in spring.

Abstract. Amiri ZS, Akbarzadeh K, Douraghi M, Abdi KM, Afshar AA, Ghaffari J, Kordshouli RS, Akbari M, Rafinejad J. 2021. Effectiveness of maggot extractions and secretion (E/S) of Lucilia sericata in reducing wound surface in an experimental scalding burn injury. Nusantara Bioscience 13: 11-15. Lucilia sericata larvae have been successfully used as medicinal larvae for wound healing. This study was performed to evaluate the therapeutic effects of the primary ointment made from excretory-secretory substances of L.sericata larvae on experimental burn wounds on rabbits under laboratory conditions. Extraction of ES from the third stage of L.sericata larvae and antibiogram testing was done. Four rabbits were randomly divided into four groups; three standard third-grade burn wounds were created on the back of each rabbit for intervention groups (B, D) of wounds were used respectively from the original ointment made from ES and ES without accompanying material. Nitrofurazone ointment was used for the positive (C) and placebo ointment was used for the negative (A). On the 21st day, all scars of wounds in groups B and D were separated and the wound was free of infectious tissue, whereas in groups A and C that the scars were clinging to the base. The level of the ulcer was significantly lower in the E/S intervention group and the infectious tissue was not observed during the treatment of group B and D wounds. Methicillin-resistant Staphylococcus aureus (MRSA) did not show resistance to excretory-secretory substances of L. sericata larvae. The debridement and recovery process was faster in the ES-treated group and the initial ointment than in the control group. The results showed that maggot extractions and secretion (E/S) of L. sericata in reducing wound healing is appropriate for treatment.
