摘要
采用室内观察和林间监测相结合,对茶籽象甲在江西地区油茶林的生活史和发生规律进行调查观测.结果表明,茶籽象甲在江西地区2年发生1代;成虫于4月下旬出土并为害茶果,5月开始在茶果上产卵;7月幼虫开始脱离茶果并进入土中,11月以老熟幼虫在土中越冬直至第2年的8月;幼虫在土中化蛹、羽化后,成虫继续生活在土中至第3年4月下旬出土.茶籽象甲在油茶林的发生与土壤湿度相关,湿润的土壤环境更适宜幼虫越冬;且位于阴坡和临近水源的油茶林被害较严重.
Abstract
This study was combined indoor observation and forest monitoring to investigate and observe the life history,and occurrence patterns of Curculio chinensis weevils in Camellia oleifera forests.The results showed that C.chinensis weevil occurs once every two years in the Jiangxi region.Adults emerged from the soil in late April and caused damage to fruits of C.oleifera.They began laying eggs on the fruit of C.oleifera in May;In July,the larvae begin to detach from the fruit of C.oleifera and enter the soil.In November,they overwinter in the soil as mature larvae until August of the second year;After the larvae pupate and emerge in the soil,the adults continue to live in the soil until emerging from the soil by late April of the third year.The occurrence of C.chinensis was related to soil moisture,and a moist soil environment was more suitable for larvae to overwinter;C.oleifera located near shady slopes and water sources were more severely damaged by C.chinensis.
