Cordyceps Fungi and Ants

Note:  The following post is not for the squeamish. You probably shouldn't watch the videos right before lunch.

Seems like there has been a lot of press lately about the "zombie ants" caused by fungi of the genus Cordyceps. The afflicted ants stagger about before they die, hence the name "zombie." At the time of death the ant typically attaches itself to a leaf and becomes a stiff fungal-spore salt shaker.

David Attenborough gives a good introduction to the fungus:

Of course, myrmecologists have known about Cordyceps for a long time, but the new interest has lead to some cool new discoveries. In the article by Bateman, it is suggested that the chemical produced by the fungus that makes the ant stumble around may be similar to LSD. Also, weaver ant workers may be able to recognize diseased individuals and may have some behaviors to cope.

The video that accompanies the Bateman article:

Do you think this research would have gotten as much press if they had merely said the ants were infected by a fungus?

    Hello again! You´re posting so quickly, it´s hard to keep up the pace.
    Anyhow, regarding the funghi the problem is of course not only the fact that insects have their little illnesses too.
    What is very interesting, though, is the fact that these spores of the fungus seem to remotecontrol the sick individual and it´s behaviour.
    And then there are suddenly new ways of looking at human infections - here, too, we can find behaviour seemingly dictated by the illness.
    For example the reaction time of somebody driving a car can be significantly slowed down by a simple flu - even if the infection is otherwise not consciously noticed.
    And sneezing isn´t only a way of getting rid of byproducts of infections, but a quite ingenious way of spreading the disease itself... And thus we come to see in an ant what might, in different ways, affect us all.
    Keep up the good work!

    Why hasnt this been explored as a fix for the fire and plague in the southern US? Or has it? It seems like instead of using poisonous chemicals that this natural fungus coukd be used to retard the advance of the fire ant.
