Mosquitoes are involved in the transmission of a wide range of diseases and among them, Culiseta longiareolata, acts as a vector of avian malaria, tularemia and several arboviruses like West Nile fever. The current study was conducted to determine the susceptibility of C. longiareolata against deltamethrin 0.05% (pyrethroids), fenitrothion 1.00% (organophosphate) and bendiocarb 0.10% (carbamate). Mosquitoes were collected from different parts of Urmia county, the capital of West Azerbaijan. In the current study, 443 empty 3 - 5 days old adult female C. longiareolata were used for susceptibility tests. The susceptibility status of C. longiareolata was determined using WHO's recommended procedure. The results indicated higher mortality rates of Culiseta longiareolata against studied insecticides. Culiseta longiareolata, was resistant to all studied insecticides (deltamethrin, mortality rate: 62.50%, fenitrothion, mortality rate: 35.96% and bendiocarb, mortality rate: 20.16%). The current study represents the first report of susceptibility status of C. longiareolata to fenitrothion and bendicarb in Iran. Considering the climatic diversity and geographical conditions of northwestern Iran, reports of resistance of other mosquitoes' of this region, the susceptibility status of medically and veterinary important mosquitoes should be given serious attention.

Objective: Delusional parasitosis (DP) is one type of psychotic disorders. It is a multifactorial disorder with different etiologies. Given that very little attention is paid to entomological survey in these cases, a comprehensive study was designed and performed for the first time in Iran on a suspected DP case and its home from Shiraz during 2018–2019. Methods: In this study, entomological survey, dermatological studies, and psychological and psychiatric interventions were done respectively on a 40‐year‐old man who was referred to as a suspected case of DP. Results: No medical importance arthropods were collected from the patient's home. He was not infected with lice and other ectoparasites. Skin samples were negative for scabies, but he was infected with Demodex folliculorum at low level. Psychiatric studies showed that he was a secondary DP case with depression. No effect and partial remission were reported after treatment with risperidone (2–6 mg/d) and olanzapine (5 mg/d), respectively. Therapeutic effects of hypnotism were also not satisfactory. Conclusions: In Iran, the most important challenges these patients faced with are as follows: the absence of a specific referral center, patients resort to self‐treatment or traditional methods, and lack of a certain duration and dosage of antipsychotic for these cases. Comprehensive clinical trials should be done on this rare syndrome at the national level for better understanding the epidemiological profile of DP and finding the best method of treatment for Persian community.

Anopheles maculipennis complex species is considered as one of the most important species complexes with 12 species and significant role in the transmission of important diseases such as malaria, lymphatic filariasis and multiple Arboviral infections. The aim of the present study was to analyze Internal Transcribd Spacer (ITS) 2 fragment among Anopheles maculipennis species complex in West Azerbaijan Province, Iran and also to identify different species of An. maculipennis using ITS2 fragment. Adult and larval specimens of different mosquitoes' species were collected from the northern, southern and central parts of West Azerbaijan Province. Adult mosquitoes were collected using standard methods of indoor and outdoor hand catch, human and animal bait and light traps. Also larvae were caught using dipping method during May- Sep 2016. After DNA extraction, ITS2 fragment was amplified and analyzed using Bioinformatics tools. Totally, 271 specimens belonged to Genus Anopheles [158 samples of An. maculipennis (adult: 50, Larvae: 57), 101 An. claviger (adult: 21, larvae: 80) and 12 specimen of An. superpictus (adult: 3, larvae: 9)] were collected from different parts of the province. Also, the presence of at least two species of Anopheles maculipennis species complex (An .maculipennis and An. Persiensis) was concluded. Based on the reported differences between these species, accurate identification of these species in terms of their ecology, vectorial capacity and their insecticide resistance profile is recommended. Also, other molecular markers such as COI, should be examined for better resolution of species composition in An. maculipennis. [ABSTRACT FROM AUTHOR]

Objective: Among the mosquitoes, Culiseta longiareolata plays a notable role in the transmission of avian malaria, tularemia and arboviral diseases, including West Nile fever. We conducted this study to characterise the cytochrome oxidase I (COI) and internal transcribed spacer 2 (ITS2) fragments of Cs. longiareolata in northwestern Iran to determine the classification status of this species., Methods: The COI and ITS2 fragments from six populations of Cs. longiareolata were amplified, sequenced and analysed. For phylogenetic analysis, the evolutionary history was estimated using the Tamura-Nei-based Maximum Likelihood approach., Results: Thirteen sequences (six for ITS2 and seven for COI) from six populations of Cs. longiareolata were acquired and deposited into the GenBank. Phylogenetic analysis showed that the COI sequences from the current study cluster together with the same species from other parts of the world. Moreover, the ITS2 sequences of the current study and sequences retrieved from the GenBank, despite intraspecies variation, fall into a distinct clade with acceptable bootstrap values., Conclusion: Notable genetic variations were observed between various Cs. longiareolata populations based on the evaluations of ITS2 and COI fragments. By conducting such studies, the exact classification status of this species can be determined.
