Occurrence regularity and control of Moritziella castaneivora Miyazaki

栗苞蚜Moritziella castaneivora Miyazaki于2004年在日照首次发现。该虫1 a发生10～13代。对日本栗的各个品种危害都很严重,也危害中国板栗,但危害程度较轻,且仅局限在日本栗引种栽培区附近。选用10%吡虫啉可湿性粉剂、5%啶虫脒可湿性粉剂、1.8%阿维菌素乳油、15%哒螨灵乳油和25%三唑锡可湿性粉剂等5种常规药剂进行田间防治试验,结果表明吡虫啉防治效果最好,其次是啶虫脒、阿维菌素。专业杀蚜药剂的防治效果明显好于专业杀螨药剂。
