摘　　要：栗苞蚜（Moritziella castaneivora Miyazaki）是近几年山东省栗产区危害日趋严重的新入侵害虫之一。在山东一年发生10余代,以受精卵越冬,翌年4月中下旬孵化为干母,下旬羽化为成蚜行孤雌生殖,8-9月虫口密度最大,9月中旬至10月上旬产生两性蚜交配、产卵越冬。室内浸渍法试验结果表明,杀虫剂抗蚜威、吡虫啉、氯噻啉、阿克泰、阿维菌素等,药后48 h对栗苞蚜的校正死亡率达91.3%-97.2%。Moritziella castaneivora Miyazaki is one of the newly invasive pests which does more and more serious damages on the chestnut in Shandong province recently. The pest has about ten generations per year in Shandong province and overwinters as oosperm. It hatches fundatrix in the middle or last ten days of next April and emerges and makes parthenogenesis in the last ten days of April. The density of the pest becomes the highest between August and September. From the middle ten days of September to the first ten days of October, Moritziella castaneivora makes gamogenesis and ovipositing in order to overwinter. The immersion experiment in the laboratory indicated that many pasticides had high efficiency on controlling this pest, the mortality could reach to 91.3-97. 2% after immersion 48 hours by the pesticides, for example Pirimicarb, Imidacloprid, Imidaclothiz,Tahiamthoxam and so on.
