A Strain on Ant Relations

Back in February 2003 I posted about the Agricultural Research Service's efforts to find a biological control for the red imported fire ant (Solenopsis invicta). Now a kind reader has pointed out this March 2004 article from AgNews, about the detection of a protozoan (Thelohania solenopsae) in wild populations of the ant. Discovered in more than 75% of the Texas counties where the red imported fire ant is found, this strain of Thelohania solenopsae appears to have found its way to the ants without human intervention, and tests show that it is different from the strain used in laboratory tests.

Thanks to Thomas D. for sending in the link to this story.
