Myiasis is the invasion of organs and tissues of humans or other vertebrate animals by fly larvae. The first reported case of myiasis in Iran was ophthalmic myiasis, which was reported in 1975. Since then about 81 cases of human myiasis have been reported in Iran up till 2017. According to this study, all types of myiasis were reported from different parts of Iran. Vectors species of human myiasis in Iran are: Oestrus ovis, Chrysomya bezziana, Dermatobia hominis, Hypoderma bovis, Rinoestrus purpureus, Lucilia serricata, Eristalis tenax, Sarcophaga haemorrhoidalis, Sarcophaga fertoni, Wohlfahrtia magnifica, Wohlfahrtia nuba, Wohlfahrtia vigil, Cynomyopsis cadaverina, and Psychoda albipennis. There were two age peaks of myiasis infection in Iran: 21- 40 years old, and 65 years old . Specific and primary treatment is removal of larvae from infected tissues . Ironing is an effective way to eliminate eggs, also wearing long sleeve clothes to cover wounds and avoiding outdoor sleep are another way to prevent infection with flying larva. The aim of this review was to determine the prevalence of myiasis in different parts of Iran in order to determine and prioritize the methods of control based on the results.

Objective: To evaluate the susceptibility of Anopheles stephensi (An. stephensi) Liston, the main malaria vector in southern Iran, to WHO recommended insecticides. Methods: Larvae of An. stephensi were collected from three different larval habitats in both urban and rural area of Bandar Abbas city and one rural area in Rudan county southern Iran. WHO standard method was used for evaluation of adult and larval mosquito susceptibility. Bendiocarb, permethrin, lambda-cyhalothrin, deltamethrin as insecticide and temephos and chlorpyriphos as larvicide were used at the diagnostic dosages recommended by WHO. Results: Findings of this study showed all larval populations of An. stephensi were completely susceptible to temephos and candidate for resistance to chlorpyriphos. Adult mosquitoes in rural areas of Bandar Abbas city were resistant to pyrethroid and carbamate insecticides. Conclusion: Comparison of the results of this survey with previous studies indicates that the resistance to pyrethroids and carbamates in this malaria endemic region is increasing. Wide use of pesticides in agriculture is certainly effective in increasing resistance. The inter-sectoral coordination and collaboration in health and agriculture seem to be necessary to manage insecticide resistance in malaria vectors.
