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。在山东省1年发生10余代,以卵或成蚜越冬,翌年4月中下旬孵化为干母,4月下旬羽化成蚜行孤雌生殖,8月～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、噻虫嗪、阿维菌素等,药后48h对栗苞蚜的校正死亡率在91·3%～97·2%以上,均有较好的防效。Moritziella castaneivora Miyazaki is a newly invasive pest, that cause more and more serious damages on the region of Moritziella in Shandong Province recently. The aphid has about ten generations per year in Shandong Province and overwinters by eggs. The fundatrix hatches in the middle ten days or last ten days of April and the parthenogenesis adults emergence in the last ten- day of April. The density of the pest become highest between August and September. From the middle ten days of September to the first ten days of October, M. castaneivora makes gamogenesis and oviposition in order to overwinter. The biological survey of several pestisicds by immersion in the laboratory indicated that many pesticides had highly effective in controlling this pest, and the mortality by Pirimicarb, Imidacloprid, Imidaclothiz, and Tahiamthoxam can reach to 91.3 % - 97.2 % after 48 hours.
