摘要
胸白偏健Hemisosibia thoraica sp.nov.是我国亚热带地区重要的生态林害虫,2008年首次在浙江遂昌发现该虫雄虫,其生物学特性尚未见报道。本研究通过林间调查和室内饲养观察其生物学特性。结果表明:胸白偏健在浙江1a发生1代,以卵越冬;4月下旬越冬卵开始孵化,若虫可危害至9月初;成虫9月初始现,9月中旬达高峰;成虫交配后即开始产卵,产卵高峰出现在9月下旬至10月上旬,卵主要分布在苦槠Caolanopsis sclerophylla上部。
Hemisosibia thoraica is an important insect pest in subtropical areas in China. It was firstly found in Suichang in 2008. Till now,there was no reports on its bionomics. The bionomics of H. thoraica were observed by field survey and indoor rearing. H. thoraica had 1 generation a year,and overwintered as egg in Zhejiang province. The egg hatched in late April and the nymph could be found till early September in forest. The adult emerged in early September,and the peak of emergence appeared in middle September. The adult laid eggs soon after mating and the peak of oviposition was from late September to early October. Eggs mainly distributed on the top of Castanopsis sclerophylla tree.
