Abstract
Background and purpose: Çonsidering the role of mite in causing severe allergic reactions in sensitive individuals, particularly women, a study was done to determine the effects of mites in residents of sari township in 1999-2000
Materials and methods: This was a desciptive study done on the residens in sari. Sampling was done randomly in 80 residential places. Samples were collected from mattresses, pillows and carpets by vacume cleaner collected material was kept in a plastic bag and sent to the laboratory. 200 mgs of dust particles were placed in a petridish and observed under minocular considering the anti light property of mites, they remained under the layer of dust and were picked up by an entomology needle and kept in 70% alcohol. Lighting of sample, neutraliztion and finally assembling were done in hoyer solution for identification after mounting. Âll the data about the mites were recorded in a questionnair and analyzed statistically.
Results : Ïn this study, 3400 mites were hunted and 5 species could be identified as follows: D. Pteronyssinus, D. farinae, Glycyphagus domesticus, Ë. moynei and Çheylatus malayensis. Çonsidering the identified species, it was cleared that, 30 houses(37.5%) were infected by one or more species of mites, also it was noticed that, 15% of houses had more than 300 mites.
Çonclusion: The result of this study showed that contamination rate of house with mites contaning dust was 37.5%. Çonsidering the fact that Ë. mayei, D. pteronyssinus and
D. farinae play an important role in severe allergies, and 15% of these houses had the density of more than 300 mites, this could have a complete correlation with symptoms of bronchial asthma.

Abstract
Background and purpose: Lice are ecto-parasites that play an important role in the transmission of diseases such as typhus and relapsing fever, etc. and so they have attracted the attention of many researchers. Head lice are common in most of the countries and it is of high prevalence in children between 6-11 years old. The aim of this study is to evaluate methods of fighting head lice in primary school pupils in Âmlash, Guilan.
Materials and methods: Â total of 147 pupils infested with head lice (102 girls and 45 boys) were randomly selected from the primary schools of Âmlash and two formulations of permethrin shampoo 1% and lindane lotion 1% were employed. Ïn one group the shampoo was used with the help of the researcher and in the other group the infested pupils themselves used both the shampoo and the lotion.
Results: Results indicated that there was a significant difference in the effect of the shampoo and lotion on the two genders (P<0.05). However, no significant difference was found between the two methods of use, that is, by the pupils and the researcher (P>0.05).
Çonclusion: The results of this study showed that appropriate training of the pupils in the use of drugs and providing them with health tips will lead to better results in the prevention and control of this disease.

Abstract
Background and purpose: Pediculosis is a worldwide public health concern. This descriptive study was performed on primary-school-aged children to determine the prevalence of pediculosis and its risk factors in Mazandaran Province, Iran, on basis of geographic information system (GIS).
Materials and methods: A random sampling method was used to select 45237 school-aged children from Sari to Ramsar cities during September 2012 to June 2013. Data were collected from the selected schools by five trained nursing inspectors. A detailed questionnaire was filled for each child prior to hair examination following which examination was carried out to detect head lice as well as eggs/nits. Data were analyzed chi-square test. Finally, the GIS map was obtained in province informational chart.
Results: 823 primary-school children (of 45237) were infected with lice in Mazandaran Province. The mean infection prevalence was 1.4% in cities 5.64% in rural area from Sari to Ramsar. There were significant relationships between pediculosis and some factors (P < 0.05). GIS map revealed that the contamination was less in west than in east and central regions.
Conclusion: Increasing awareness and training of teachers and parents, as well as improving standards of personal health can significantly reduce the prevalence of pediculosis.

Abstract
Introduction: Scorpionism is one of the public health problems in Iran especially in southern and western part of the country. In these regions many people especially children are being stung by scorpions and consequently serious injuries or even death occurs. The aim of the current study was to assess the geographical distribution of scorpions with a focus on Hemiscrorpius leptorus.
Material and Method: The study was conducted using published articles and books since 1979 to 2013.
Conclusion: Southern and western provinces of the country are habitat of the Hemiscorpius scorpions. Sting of these scorpions can cause severe complications and even death of the injured individuals. People in most communities and health personnel have low information about Hemiscrorpius leptorus. Therefore, it is necessary to perform further studies on the distribution, diagnosis of symptoms, and problems associated with scorpionism.

Abstract
Background and purpose: One of the most popular methods to control the synanthropic flies is using parasitoid wasps. The aim of this study was to estimate the experimental parasitism rates of pupae of Musca domestica, Lucilia sericata, and Sarcophaga heamorrhoidalis by parasitoid wasps, including Nasonia vitripennis, Spalangia nigroaenea, and Pachycrepoideus vindemmiae.
Materials and methods: Pupae of three species of flies, including Musca domestica, Lucilia sericata, and Sarcophaga haemorrhoidalis were exposed to three parasitoid female wasps, including Nasonia vitripennis, Pachycrepoideus vindemmiae, and Spalangia nigroaenea in laboratory condition. The exposure rate was 8 wasps to 10 fly pupae on alternate days up to 5 days. The experiments were performed in triplicate and a total of 2700 fly pupae was exposed to 432 wasps. The parasitism rate and parasitoid host preferences were also determined.
Results: Total parasitism of flies was estimated at 22.17%. There was no significant differences in parasitism rate of Musca domestica, Lucilia sericata, and Sarcophaga haemorrhoidalis by Nasonia vitripennis, and Pachycrepoideus vindemmiae, but there was a significant difference in parasitism rate of house fly by the three parasitoids investigated (P<0.01). The Spalangia nigroaenea was active just on pupae of Musca domestica. The highest parasitism rate of the fly species studied was found by parasitized wasps of 5–7 days old.
Conclusion: Spalangia nigroaenea can be considered as an efficient and specific parasitoid for biological control of Musca domestica. Other wasp species, including Nasonia vitripennis, and Pachycrepoideus vindemmiae could also be used in integrated fly control programs. Also, in biological control program for flies, 5-7 day parasitoid might be more effective.
