- Abstract
The wing dimorphism of pear psylla (Cacopsylla chinensis) under different months and different photoperiods were studied in this paper. It was shown that there were two distinctive wing morph which changed with months. The short-wing pear psylla occurred from May to September, while the long-wing pear psylla occurred from October to the next April. Under constant temperature of 20 ℃, short photoperiod conditions (9 h light/15 h dark, 8 h light/16 h dark) induced long-wing pear psylla; while long photoperiod conditions (12 h light/12 h dark, 10 h light/14 h dark) induced short-wing pear psylla. Due to the longer body length of long-wing pear psylla induced under short photoperiod conditions, its relative wing length turned shorter. Based on the analysis of the distance between the wing vein cross landmarks under different months and different photoperiods, which exhibited the same variation characteristics in the wing dimorphism, it was deduced that the photoperiod was a major inducing factor of the pear psylla wing dimorphism.
