Leaf Cutters Ant Colony Development







Brain Development and Ants- We grow through our experiences. It could be a matter of depth or width, as in experience some about many, or experience much about one. Usually we live with a balance of both, and the brain continues to make new connections while reinforcing older ones and some connections are lost. So, if you want a healthy brain, don't do drugs, children.
Really, decent nutrition, physical exercise and learning new things are a good start.

So, what about the ants? We have learned much. At the moment, we are starting a new study titled:
Does a cabbage bait infused with an organic mystery solution affect leaf cutter colony size or behavior?
Purpose: To find possible methods of reducing foliar damage caused by leaf cutter ants.
Background: When we moved into this house in July 2009, a leaf cutter ant colony existed in the pasture. At that point, their mound was about the size and shape of an upside down salad bowl, while underground tunnels likely traveled a few meters and colony size consisted of several thousand ants. Today, the primary mound covers an area the size of a two car garage, there are several smaller mounds and entry holes throughout the pasture and our yard, tunnels and chambers, well, if someone wants to have fun with the math, let me know, colony size is likely in the several millions.
Leaf cutter ants make a living by cutting pieces of leaves and using them to grow a fungus in their underground chambers. The fungus is then harvested and eaten by the colony's members.
The leafcutters, are very interesting to observe, however they do cause a considerable amount of damage to foliage and can colonize new areas through reproduction. Gardens and reforestation projects are susceptible to considerable damage and their earth moving can affect building foundations. Currently, we do not know of natural mechanisms, such as predators or weather events, for controlling their populations at this site. Common local methods for their eradication is the burning of diesel fuel in their tunnels (really fun for humans) or use of a fungicide that targets their food source (not as exciting as the former).
We have tried the fungicide, and the ants initially show curiosity by taking a few pellets, then after a few applications, they move the pellets off to the side of their trail.
Our Test: We have received an organic cabbage bait that is designed to kill the ants, thus reducing the size or even eliminating a colony. Each morning this week, I spread spoonfuls of the cabbage substance on several trails. On most mornings, within ten minutes they hauled a few pieces toward their tunnels. When I returned home in the late afternoons, 90% of the cabbage was gone. So, are they bringing all of the cabbage to their nests? (Bias, says yes, absolutely) Are other animals eating the cabbage? (bias, says, no, absolutely not) But ethical and true science is objective, biases removed. It has been difficult to assess because I have other responsibilities - like making my own living. So, without continual observation, I really don't know what is happening to all of the cabbage. Have I noticed any change in behavior or numbers of ants? No.

More research, and thus brain development in the future! Time to apply more of the cabbage.
