木曽川下流域における冬期の主なユスリカ幼虫相とその羽化期を調べるため,2006年2月に底質を採集し,その中に含まれる幼虫を飼育し羽化させた.その結果,9種が同定され,優占種はStictochironomus akizukii,Hydrobaenus kondoi,Tanytarsus takahashii,Einfeldia dissidensであった.これら4種はH. kondoi→S. akizukii,T. takahashii→E. dissidensの順で羽化した.羽化までに必要とした有効積算温度と採集地点付近の水温から,野外における越冬世代の羽化期は,H. kondoiは3月上旬まで,S. akizukiiおよびT. takahashiiは3月末から5月上旬,E. dissidensは4月下旬から6月中旬と推定された. / Species composition and period of emergence were investigated for overwintering Chironomidae at the lower reaches of the Kiso River by rearing larvae to obtain fundamental information for drafting a plan to prevent outbreaks of nuisance midges. Adults of 9 species emerged from the substrate samples in February 2006. The four most abundant species, Stictochironomus akizukii, Hydrobaenus kondoi, Tanytarsus takahashii and Einfeldia dissidens, occupied 88.0% of the total abundance. Using effective accumulative temperature for emergence and in situ water temperatures, the in situ emergence periods of the overwintering generation in 2006 were predicted as until early March for H. kondoi, from the end of March to early May for S. akizukii and T. takahashii, and late April to mid-June for E. dissidens.
