JO(J F ­NF 2 F A N! C,NC 2 C ­N­ FC Remarks. Psylla OR Cacopsylla pyrisuga FROM JAPAN (KUWAYAMA 1908; MIYATAKE 1964; INOUE 2010) AND KOREA (SHINJI 1944; KWON 1983; PARK 1996; KWON et al. 2016) ARE MISIDENTIFICATIONS OF C. burckhardti, AS WAS SUGGESTED bY LUO et al. (2012). THE RECORDS OF C. pyrisuga FROM THE RUSSIAN FAR EAST (KONOVALOVA 1988; GEGECHKORI & LOGINOVA 1990) PRObAbLY ALSO CONCERN C. burckhardti.
C. burckhardti IS MORPHOLOGICALLY SIMILAR TO THE WEST PALAEARCTIC C. pyrisuga. IT DIFFERS FROM THE LATTER, AS ADULT, IN THE PARAMERE WHOSE ANTERIOR MARGIN IS MORE PRODUCED AND POSTERIOR MARGIN IS MORE SINUATE (FIGS. 21‒24), THE APICAL DILATATION OF THE DISTAL PORTION OF THE AEDEAGUS WHICH IS SLIGHTLY LONGER AND MORE ANGULAR (FIGS. 25, 26), THE TIP OF THE FEMALE PROCTIGER (FIGS. 29, 30) WHICH IS MORE bROADLY ROUNDED, THE DORSAL AND VENTRAL VALVULAE (FIGS. 31, 32) WHICH ARE STRONGLY CURVED, AND, AS FIFTH INSTAR IMMATURE, IN THE FOREWING PAD (FIGS. 27, 28) WHICH IS SLIGHTLY ANGLED ANTERIORLY AND IN THE MIDDLE OF THE OUTER MARGIN (SEE ARROWS), RATHER THAN ROUNDED AND ALMOST STRAIGHT.
C. burckhardti, AS C. pyrisuga, IS UNIVOLTINE AND OVERWINTERS AS ADULT ON CONIFERS. THERE ARE NO REPORTS OF THIS SPECIES DAMAGING CULTIVATED PEARS IN KOREA. WHEREAS IN JAPAN, THIS SPECIES IS A COMMON PEST OF CULTIVATED PEARS (MIYATAKE 1979), THIS IS NOT THE CASE IN KOREA.
