Predatory capacity of Adalia angulifera (Coleoptera: Coccinellidae) larvae on Myzocallis coryli (Hemiptera: Aphididae) in Chile

In La Araucanía, the filbert aphid Myzocallis coryli (Goeze) is a pest that can cause various types of damage to hazelnut (Corylus avellana L.) including reduction in nut size and nut emptiness. M. coryli can also leave hazel leaves susceptible to the fungus known as fumagina (Capnodium sp.), which...
