桐花树毛颚小卷蛾生活史及食性初步研究

摘要

Life history and feeding habits of Lasiognatha Cellifera in Quanzhou Bay Estuarine Wetland were carried out, and the results showed that:(1)The pest had 8 generations a year in Quanzhou Bay Area and the gene­ rations overlapped, the leaf wintering of larvae was done by curling on Aegiceras, beginning to cocoon and to pupate in early March next year and the eclosion into adults started in late March;there were two obvious hazards peak in one year, respectively, in mid­May and late September. (2)Lasiognatha Cellifera was a major pest in Quanzhou Bay mangroves, with the insect feeding Aegiceras only, but not feeding K.obovata and A.marina.%对泉州湾河口湿地红树林桐花树毛颚小卷蛾生活史及食性开展初步研究，结果表明：（1）桐花树毛颚小卷蛾在泉州湾地区1年发生8代，世代重叠，以幼虫在桐花树叶片上卷叶越冬，翌年3月上旬开始结茧化蛹，3月下旬开始羽化为成虫；1年内有2个明显的危害高峰期，分别出现在5月中旬和9月下旬。（2）桐花树毛颚小卷蛾是泉州湾红树林的主要害虫，该虫只取食桐花树，不取食秋茄和白骨壤。
