摘要: 2018年7–12月，对上海主要阔叶乔木叶螨种类进行调查，并对槭树小爪螨Oligonychusilicis进行为害程度和越冬情况调查。结合野外调查结果和文献记录，结果表明，上海园林阔叶乔木叶螨种类有17种，其中3种为国内新记录，分别为栗树小爪螨Oligonychuscastaneae，朴树始叶螨Eotetranychusnomurai和槭树小爪螨；在上海地区首次发现神泽氏叶螨Tetranychuskanzawai为害玉兰Magnolia denudata，尼氏真绥螨Euseiusnicholsi为害栾树Koelreuteriapaniculata和无患子Sapindusmukorossi。野外观察发现，槭树小爪螨为害红花槭Acer rubrum一直持续到10月中旬，且不在落叶上越冬。
