  Varroa spp. is an important ectoparasite in the honey bee that is distributed worldwide and it may cause to decrease in the population in the honey bee colonies. This study was conducted to determine the frequency of seasonal distribution of Varroa mite in apiaries of Kerman province from 2017-to 2018. 1500 hives were sampled randomly in different apiaries in the Kerman province. Detection of   Varroa spp. infestation in adults honey bees was conducted by Ether wash. The prevalence of Varroa spp infestation in apiaries was 32.9%. The highest frequency of infection in winter was determined as 46.6% and the lowest infection rate was found in spring (24%). The highest and lowest mean density rate of infestation were 33% and 17%.  Regarding the rate of prevalence of Varroa spp in the apiaries of Kerman province, it needs to have a regular control program in order to decrease the rate of infestation in this region.

  Due to the harmful effects of using chemical pesticides to control Varroa in honey bee colonies, the use of non-chemical methods such as hygenic behaviors of honey bee has been considered. The hygenic behaviour includes detection of dead, infected or abnormal infants in breed cells, uncapping, removing the broods and grooming to remove Varroa from the body. These hygenic behaviours are important defense mechanisms against a variety of pathogens such as bee bacteria, fungi and also Varroa mites. In this research, the hygenic mechanism and grooming behaviour of Iranian honey bees against Varroa mite was investigated in two generations. The study was accomplished on 60 colonies (30 resistant and 30 sensitive colonies as control) of Alborz National Institute of Animal Science Research in two sessions: one day a week from September to October 2014, and from June to October 2015. To measure the grooming behaviour, grease-treated plates were installed in the floor of the test bed and the number of healthy and unhealthy Varroa Mite on the plates was counted. The rate of uncapping and removed of dead broods was determined in resistant and control colonies on June 2014 and October 2015. To determine the hygenic behaviour, liquid Nitrogen was used to kill pupae. The number of uncapped and discharged cells was counted in three periods of 24, 48 and 72 hours after the application of liquid nitrogen. Colonies that removed more than 95% of dead, infected or abnormal broods within 48 hours were considered as very hygienic colonies.The average of grooming behaviour in 2014 and 2015 was 61 ± 1 and 65 ± 3 per colony respectively (p Manuscript profile

  Varroa destructor Anderson & Trueman is one of the most perilous pests of honey bee colonies around the world. So, natural products such as plant essential oils are considered as a suitable replacement for chemical compounds in pest control. This study was planned to check the respiratory killing effect of essential oils of four perennial Satureja species on Varroa destructor and Apis mellifera meda in an apiary. The sensitivity of the mite to four essential oils was according to the following, S. khuzestanica Jamzad, S. rechingeri Jamzad, S. mutica and, S. bachtiarica Bunge. The calculated LC50 values for S. khuzestanica Jamzad and S. rechingeri Jamzad were 151.6 and 161.77 ppm for Varroa mite and 328.22 and 337.7 for honey bee, respectively. Qualitative analysis of essential oils showed that the major component of the oils for all species was carvacrol. Satureja khuzestanica Jamzad and S. rechingeri Jamzad had the highest amount of carvacrol with 93.5% and 88.8%, respectively. In general, the essential oil of S. khuzestanica Jamzad and S. rechingeri Jamzad had a high ability to control Varroa mites. Manuscript profile

  The paper deals with the some of the more important parasitic mites associated with honeybees. Varroa destructor Anderson and Trueman is worldwide and the most familiar and destructive of the bee mites, causing death and damage to large numbers of honeybees. Known from Asia, the tropical bee mites Tropilaelaps clareae Delfinado and Baker and T. koenigerum Delfinado Baker and Baker, are spreading and are a potential threat to bee keepers in many parts of the world. Two new species of Tropilaelaps have recently been described. Acarapis woodi Rennie, known as the honeybee tracheal mite (H.B.T.M.) reduces the resistance of bees to other parasites and diseases, shortens the life cycle and in heavy infestations can block the tracheae of bees.

  Varoasis is one of the most important diseases of honey bee which caused by Varroa mites.This parasitic diseasecan destroy bee hives colonies at short time period.Varroa mite cause weakness in bee colonies because feedingvia bee larves and decrease bee hive production.So, chemical treatments were used in apiaries around the worldfor controlling of this disease.In this study,the effects of Gabon PA92 and Bayvarol was evaluated.30 bee hivesin Nazar abad of Karaj Province in 3 experimental groups were examined.In each bee hive,we took 50 adult beesand 50 honey bee pupa and their mites were separated so primary infestation was determined.After using Gabonand Bayvarol,rate of infestation was determined again.In control group because of unusing drug,rate of infestationwas higher but in groups of Bayvarol and Gabon,rate of infestation was decreased from 7.2% to 0.3 and 7 to 0.1 inadult bees and 5.7% to 0.2 and 5.4 % to 0.1 in pupa respectively.Effectivness of drugs was 95.8 % and 98.5 % inadult bees and 96.4 % and 98.1 % in pupa for Bayvarol and Gabon respectively.Although,the treatment effect ofGabon was a little more than Bayvarol but this difference was not signifcant (P>0.05).

  Infection rate of suburb bee hives to parasites Nosema apis, Varroa spp. and Acarapis woodi was evaluated in Miyaneh region, because of their importance and high distribution in Iran. For this reason, 150 hives were chosen randomly from 30 different bee farms. Selected bee hives were transferred to laboratory for light microscopic examination. From 150 studied hives, 129 hives (81%) were infected to Nosema apis, 7 hives (4.43%) were infected to varroa spp. and did not observed any infected hives to Acarapis woodi. According to the results, bee hives had high infection rate to Nosema apis and so, planning management programs for parasite control and preventing its spreading is necessary by veterinary organization.

      Varroa is one of the most dangerous honey bee parasites, which causes serious damages to the bee industry. By now, various herbal and chemical drugs had been used against the parasite. In this research, the effect of 7 treatments including: tobacco, harmel and, thyme extracts, tobacco, harmel and thymus smokes and a control were studied on Varroa in 21 honey bee colonies as a completely randomized design (CRD) at three replications. The rate of hive contamination to Varroa at the beginning and end of the experiment and daily rate of varroa and worker bee mortality were recorded. There was no significant difference between experimental hives in view point of contamination toVarroa, at the beginning of the study.  However, significant dissimilarity was found out among treatments at the end of experimental period. Mortality rate of Varroa in different days and the whole period of the study was significantly different in treatments. Results revealed that tobacco and  harmel extracts caused the most Varroa and honey bee mortality, respectively. Manuscript profile
