摘　　要：为了查清云南板栗实象甲的种类、分布及危害，从１９９１～１９９５年，采集了云南省１７个地州，９２个县（市），１５１个点（镇、乡、村）所产的板栗，放置养虫盘内，逐日观察记录，收集越冬幼虫（自栗实脱出的老熟幼虫），饲养并进行种类鉴定．发现２种象甲：二斑栗象（ＣｕｒｃｕｌｉｏｂｉｍａｃｕｌａｔｕｓＦａｕｓｔ）为省内新记录；柞栎象（ＣｕｒｃｕｌｉｏｄｅｎｔｉｐｅｓＲｏｅｌｏｆｓ）为国内分布新记录．前者为优势种，后者仅分布于滇中和滇西部分县．百粒被害率从０～８６７％，平均被害率为１５％．In order to define the distribution and infection of the Chestnut Weevil species, the chestnuts from 92 counties from Yunnan were collected, observed and recoreded carefully. The number of the hibernating lavies from the chesnuts and the rate of damage were calculated, and the species were identified. Two species were Curculio bimaculatus (Faust) and Curculio dentipes (Roelofs).The first was the dominant species and the species was a new record in Yunnan,the later was only found in middle and west of Yunnan and the species was a new record in China so far.The damage rate was from 0 to 87 6%,15% for average.
