摘要

The white peach scale (WPS), Pseudaulacaspis pentágona (Targioni-Tozetti) (Homoptera: Diaspididae), was detected in Puerto Rico on Prunus pérsica (L.) Batsch at the Agricultural Experiment Stations in Corozal (18°19.366N, 66°1.606W; 210.3 meters above sea level) and in Adjuntas (18°10.528N, 066°47.964W, 571.5 meters above sea level). The insect was detected 16 January 2003 in the field on peach trees branches in an experimental orchard of cultivars Flordaprince, Tropic Beauty, UFGold and Flordaglo. The WPS was identified by P. Stansly. Peach trees were imported to the island 25 January 2002, from Florida, under Puerto Rico Import Permit number 0102-12 and Phytosanitary Export Certificate 581.031(23). These represent a new introduction of P. pérsica commercial varieties to the island. Martorell (1976) reported that P. pérsica was grown occasionally in Puerto Rico. Wolcott (1936) indicated that peaches were severely affected by the scale insect to the extent that the trees no longer existed on the island. Previous to planting, the trees were treated with an insecticide solution. Only trees of cultivar Flordaglo were infested with WPS, thus suggesting varietal preference by the WPS.
