Description:
The giant bark aphid is the largest aphid in North America. During December 2001 and through most of March 2002, an outbreak of this aphid was found covering about the eastern quarter of Texas. They mainly attacked oak trees, especially live oak and water oak. Natural enemies, such as lady beetles, played an important role in controlling aphid populations. During winter months when temperatures are cold, predator and parasite insects are not very active, and this may be the reason aphid populations became so large early in 2002.
