摘　　要：对中国梨木虱不同月份和不同光周期下的翅型变化进行研究。结果表明,梨木虱翅型随月份发生明显变化,5—9月为短翅型,10月至次年4月为长翅型。恒温20℃条件下,短光周期(9 h光/15 h暗、8 h光/16 h暗)可诱导产生长翅型,而长光周期(12 h光/12 h暗,10 h光/14 h暗)可诱导产生短翅型。短光周期下长翅型梨木虱的体长相对较长,因而其相对翅长反而较小。对不同月份和不同光周期下翅脉交叉地标点的距离变化特征进行分析,发现两者诱导的翅型分化特点一致。由此,基本可确定光周期是影响梨木虱翅型变化的主要因子之一。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.
