San Antonio's Express News has an interesting article about the new biological control program in Texas that targets red imported fire ants (Solenopsis invicta). Armed with vials of Brazilian phorid flies (Pseudacteon tricuspis) raised in the USDA's Florida research facility, Texas Cooperative Extension worker Molly Keck is tracking down fire ant mounds in San Antonio and releasing the flies, who pounce on their victims and deposit an egg inside each one's head. But maybe the real story here is Molly's mom, who definitely goes above and beyond her parental duties to walk the area with a cattle prod, zapping the ground to agitate the fire ants and get them out where the flies can find them. Would your mom do that for you?
You can read more about the program in this Texas A&M press release, and an ISW post from 2003 about the Florida program. Thanks to nuthatch over at bootstrap analysis for sending in a link to the article.
