Boxwood psyllid

 

Boxwood psyllid, Psylla buxi, is a common pest of boxwood, particularly in landscape settings. Feeding by the nymphs and adults causes a characteristic cupping of the new growth. The nymphs produce a waxy secretion giving them a woolly appearance. There is one generation a year. Eggs hatch (eclosure) was noted on April 2 in the North Willamette valley in 2010, April 5 in the Portland metro area in 2007. Adults were noted by the second week of May in western Oregon in 2006.
