Introducing of a New Sting Agent of Velvet Ant Dentilla sp. (Hymenoptera: Mutillidae) in Kashan, Centerl of Iran (2014 - 2015)
Velvet ants (Mutillid wasps) are among the venomous and stinging insects, which their existence has been reported from different areas of Iran.
Since no study has been done so far in Iran in regards to their sting, their clinical complications and their sting are studied for the first time in Kashan.
In this descriptive cross- sectional study that was performed during 2014 - 2015, 49 individuals stung by velvet ants in the residential areas in Kashan were assessed. Identification of the sting agent was according to the morphologic specifications of the collected samples of the insect in the houses of the injured. Sting complications in the individuals were studied according to the clinical manifestation and the time of the sting, which was from June to September.
In this study, the sting agent was identified as velvet ants, Dentilla genus. Most sting cases were in the age group of 11 - 20 years with 30.5% and the lowest belonged to the age groups of 31 - 40 and 41 - 50 years. The first sign of the sting was a severe and sharp pain. The highest percentage of redness in the individuals was 47% in the first day, and the lowest belonged to four or five days after the sting with 2%. Intense itching was one of the main symptoms of velvet ant stings. In the final stages of pain and itching, hemolysis and bruise signs were observed as brown spots.
Velvet ant stings have not been reported so far from Kashan. Due to the high cases of stinging in the women carpet weaving workshops, their sitting rooms, and bed rooms, it can be concluded that this arthropod is a domestic pest. Therefore, control and prevention of its potential damages must be programmed accordingly.
