In the Apazapan population, 26 out of the 98 colonies of E. tuberculatum (27%) were polygynous, with a median of two queens. Some of them included parasitic queens of E. parasiticum. Adult parasites were found only in the site 1, and only during two out of six field trips. Some parasites emerged during March-April 2009 in the laboratory from three colonies collected in January 2009, implying that the parasite was still present in this site at this date.
