摘　　要：首次系统记述中国云南省松叶蜂科４属１１种的卵痕图案。研究结果表明，每针叶产１～２粒卵的种其幼虫无群集性，通常不会成灾；相反，每针叶产多粒卵的种其幼虫有群集性，通常造成灾害。卵痕图案可作为种的鉴别特征，但不宜用于区别不同的属。Egg scar patterns of 11 species of the conifer sawfly family Diprionidae inYunnan are described and illustrated for the first time. These species belong to 4 genera：Diprion, Nesodiprion Neodiprion and Gilpinia, The egg scar patterns can be used asdiagnostic characters for the species，b ut can not be used for the distinguishment ofgenera. A key based on egg scar patterns is given for the species．The species whose femaleadults oviposit 1 or 2 eggs on one needle，the larvae are non- gregarious and usualIy causeno destruction，In contrary，the species whose female adults lay many eggs on oneneedle，th e larvae are gregarious and often cause outbreaks in the forest。
