The alternative use of biological control agents (BCAs) against leaf-cutter ants (LCAs) is in increasingly high demand due to the negative consequences of traditional pesticides. Regarding LCAs, BCAs include en
ants, leaf-cutter bees do not feed on the leaves, either directly or indirectly, but use the pieces in order to line the brood chambers in their nests. Seedchalcidsmay destroy seeds of crops such as clover. Many of the phytophagous sawflies are important pests, particularly toforest trees....
such structures have been unknown in insects. Here, we report the discovery of high-magnesium calcite [CaMg(CO3)2] armor overlaying the exoskeletons of major workers of the leaf-cutter antAcromyrmex echinatior. Live-rearing and in vitro synthesis experiments indicate that the biomineral layer acc...
GEvidently the ants usually manage to keep Escovopsis and other parasites under control. But with any lapse in control, or if the ants are removed, Escovopsis will quickly burst forth. Although new leaf-cutter gardens start off free of Escovopsis, within two years some 60 percent become i...

have highlighted the potential importance of stigmergy, tree height and negative feedback control to drive the functioning of task partitioned foraging in leaf-cutter ants. Our work provides a foundation to help generate experimentally testable hypotheses for how this behavioural phenomenon may have ...
