Hello in Oman......

After a few fruitless queries, I think I finally found the scientific name for the fly that is an endoparasitoid of Apis mellifera. That's what you wanted to know. Here is the identification:

Order Diptera (the flies)

   Family Sarcophagidae (the flesh flies)

       Senotainia tricuspis (Meigen)

I don't believe this fly has a 'common name'---certainly not one that I have been able to find yet.

I was able to find one publication with some useful (?) information for you and beekeepers in the Middle East. I believe it is published in Italian, however. This is the citation for the journal article:

Investigation on the presence in Latium of Senotainia tricuspis (Meigen) (Diptera, Sarcophagidae), endoparasitoid of Apis mellifera L. Piazza, M.G.; Marinelli, E.; Insitituto, Sperimentale per la Zoologia Agraria, Firenze, Italy, Redia, 2000, 83, pp. 111-122, 30 ref.

I found this citation and the following abstract on CAB International 2015 If you want to see a little more of the details on this article, the web address is:

This is the abstract---in English---that was reported:

'The presence of the endoparasitoid fly (S. tricuspis) of honey bees in Latium, Italy was investigated during 1997-99 in 5 provinces with 28 stations distributed in littoral and inland zones. The presence of S. tricuspis was observed in all the apiaries situated in littoral areas with significantly higher percentage than the inland ones. The results indicate that S. tricuspis prefers sunny places with sandy soil which are more suitable for pupation and overwintering of the larvae. The use of white chromotropic traps soaked in glue, arranged on the roof of the beehives, effectively controlled the dipteran population to below levels causing economic damage.

I'm not certain what they mean by 'white chromotropic traps' but it sounds like  white 'sticky traps' to me. Maybe white attracts the adult flies, but they get themselves stuck in the sticky material and don't make contact with the honey bees.

I was not aware of this pest until you asked.  I am not aware that it is established anywhere in North America.

I will share this information with colleagues in our U.S. Department of Agriculture. 

Someone there is undoubtedly aware of this pest and the possibility that it could 

be introduced into the U.S. and  elsewhere. 

Thank you for your inquiry and bringing this pest to my attention. Best wishes. 

I'm glad you are multi-lingual. I never would have found these two most recent sources. I'll see if I can get them translated.

Apparently this fly is still another pest of honey bees that we in the U.S. don't have---yet, anyway.

Reading just the tidbits I've found on this insect, it apparently thrives where humidity is a bit higher---at least in that Italian study. However, Italy is a rather narrow country with oceans all around, so I don't understand how humidity inland could be that different from what occurs along the coastlines? Also, once the pests are inside a bee colony, temperature and humidity are regulated to a certain degree by the bees themselves.

I am curious how well that 'white sticky trap' works for pest management, also.
