Predatory beetles eavesdrop on ants' chemical conversations to find best egg-laying sites
Date:8/3/2012

e ants are distributed in a patchwork on the plantations, and the patches of Azteca are essential for the survival and reproduction of the predatory lady beetle."

The patches of Azteca, which cover 3 to 5 percent of the plantation area, act as a source of adult lady beetles, which can help control the scale insects on the rest of the plantation. Since the Azteca ants nest in trees that are planted alongside the coffee for shade, eliminating these shade trees can result in the elimination of one of the most important predators of the scale insects, Perfecto said.
