Book excerpt: Excerpt from An Analysis of Pear Psylla Populations, 1977-79 In 1978, the control programs of grower 4 showed the effectiveness of strong early season control of pear psylla (fig. However, in late July an application of amitraz was required. In the absence of additional applications, the survivors initiated large late - season populations. Predator pressures in late season were low due to the lack of a major reservoir (in an adjacent un sprayed area) to furnish the initiating populations. In 1979, the early p0pula tions of immatures were reduced by insecticide applications (fig. But the survivors of the summer insecticide applications initiated a large potential population of overwintering adults in late fall. The predators were decimated by the insecticide applications and never recovered. The data demonstrate the rapid recovery of pear psylla populations when small numbers survive insecticide applications. The necessity for miticide applications indicated some weakness in the early season control or a reservoir of mites for reinfestation of the trees.

Book excerpt: Pear psylla (Cacopsylla pyricola [Foerster] [Hemiptera: Psyllidae]) is an important pest of pear in Washington. Honeydew produced by pear psylla causes fruit russet, and serious infestations can stunt and defoliate trees. Pear psylla likely arrived in the United States along with shipments of pear nursery stock from western Europe. It was first found in Connecticut in 1832 and spread to Washington State by 1939. Within a few years it became a serious pest throughout all pear growing areas in the Pacific Northwest.
