Hi, I am doing a research project on Camponotus modoc for a class. I am specifically interested in their relationship with aphids. I will be growing some bean plants and ordering a batch of 50 aphids soon. I will need to devise a setup so that the ants/aphids have access to the upper part of the plant without gaining access to the root system and soil. Does anyone have ideas of how this could be done? I will also be researching other elements of Camponotus modoc's ecology. *Note that I'm on my iPhone so I can't italicize the species names and I apologize if there are mistakes that I didn't catch.
