First record from Korea of the jumping plant-louse Bactericera gobica (Loginova) (Hemiptera: Triozidae), a pest on Lycium chinense Mill., with comments on psyllids associated with Lycium (Solanaceae)

Abstract

Bactericera gobica (Loginova) is reported for the first time from Korea on Chinese boxthom, Lycium chinense Mill. In North and Northeast China, B. gobica is an important pest of boxthorn (Lycium chinense and L barbarum) whose fruits, known as wolfberiy or goji berry, are used in traditional medicine. B. gobica is diagnosed and illustrations of taxonomically relevant structures are provided along with information on its biology. Worldwide 17 psyllid species are associated with Lycium. These belong to the genera Bactericera (5 spp.), Diaphorina (2 spp.) and Trioza (1 sp.) in the Old World as well as Bactericera (2 spp.) and Russelliana (7 spp., including 5 undescribed spp.) in the New World. One species of each Bactericera and Russelliana is polyphagous which is very rare in psyllids.
