Amoimyrmex striatus

Barrera et al. (2015) studied the diversity of leaf cutting ants along a forest-edge-agriculture habitat gradient. Their study site, in Chaco Serrano of Central Argentina, had forest remnants of various sizes within an agriculture area with wheat, soy and maize. A. striatus was the moderately abundant (17% of the 162 Acromyrmex colonies sampled). Along the forest edge it was similar in abundance to Acromyrmex lundii, with Acromyrmex crassispinus also present but occurring at a slightly lower abundance. A few colonies of Acromyrmex heyeri and Acromyrmex silvestrii were also found along the forest edge. Ten Acromyrmex nets were found within 5m of the forest edge but none were sampled 25m from the forest edge in the croplands. A. striatus was not found in the forest interior but was the most common species in the cropland matrix close to the forest edge. This suggests this species may do well in disturbed areas. In some regions A. striatus is known as a pest species (Diehl-Fleig, 1993).
