摘要：

采用野外调查和室内饲养相结合的方法,明确了沙葱萤叶甲(Galeruca daurica)的生活史和主要生物学特性,以期为该虫的预测预报和防治提供必要的基础。在锡林郭勒草原,沙葱萤叶甲1年发生1代,以卵在牛粪、石块及草丛下越冬,越冬卵最早于4月上旬开始孵化,4月下旬为孵化盛期。幼虫大量取食新鲜的沙葱(Allium mongolium)、多根葱(Allium polyrhizum)及野韭(Allium ramosum)等葱属植物。5月中旬老熟幼虫开始化蛹,6月上旬成虫开始羽化,随后进入越夏蛰伏期。8月下旬雌雄成虫开始交尾产卵。

Abstract:

Field survey and indoor experiment were applied to investigate the life history and major biological characteristics of Galeruca daurica in order to build a foundation for its forecasting and control. This leaf beetle occurred one generation each year and overwintered as eggs under cow dung, stone and thick growth of grass in Xilinguole grasslands. The overwintering eggs began to hatch in early April at the earliest and the hatching peak was in late April. Larvae greatly feed on fresh Allium plants such as A. mongolium, A. polyrhizum and A. ramosum. Old larvae started to pupate in middle May. Adults began to emerge in early June and then estivated in diapause. Female and male adults started to mate and lay eggs in August. Meanwhile, the morphological characteristics of G. daurica were described.
