López-Arroyo, 2010, personal com. • 1. The information of arthropod predators of ACP in Mexico corroborates feeding on the pest, but generally only indicates presence or absence of predators

• 2. Insect predators in Coccinellidae, Chrysopidae and Syrphidae are common predator of ACP in some places in Mexico

• 3. Chrysopidae was most often encountered on trees infested with ACP at Nuevo Leon (northeast) than any other predator Thanks
