摘    要:在实验室和野外条件下,对柳圆叶甲Plagiodera versicolora(Laicharting)的生物学特性进行了系统观察。在野外,越冬成虫于3月下旬至5月中旬陆续出土繁殖,一年能繁殖6~12代。该虫由于成虫产卵持续时间长,完成一个世代的时间短,因此世代重叠现象非常明显。11月上旬后羽化的成虫取食一段时间后蛰伏越冬。成虫产卵有一定的周期性,一般10d为一个周期,每天产卵最少1粒,最多65粒。寄主树叶老嫩程度和气候条件对各世代成虫的产卵具有显著的影响。

关 键 词:柳圆叶甲  生活史  产卵量  滞育

Abstract:Life history of Plagiodera versicolora(Laicharting) was studied in laboratory and field.In the filed,the over-winter adults began to emerge from the soil gradually from late March to middle May.This species had 6 to 12 generations a year in Jiangxi Province.Adults began to enter diapause from late October to middle November.P.versicolora has a cyclic oviposition period,each of which lasted for about 10 days.Female adult could lay at lest 1 and most 65 eggs everyday.Its oviposition was influenced significantly with the quality of host plant and temperature respectively.
Keywords:Plagiodera versicolora  life cycle  egg production  diapause
