The dependence on adult female morphology for the determination of soft scale insect species (Hemiptera: Coccomorpha: Coccidae) creates several problems. In this paper, various nymphal stages of soft scale insects from the Ankara district of Trkiye and Israel, belonging to Coccidae: subfamily Eulecaniinae, namely Eulecanium cerasorum (Cockerell), E. ciliatum (Douglas), E. tiliae (Linnaeus), Paleolecanium bituberculatum (Signoret), Physokermes piceae (Schrank) and Rhodoccus perornatus (Cockerell & Parrott) were studied. The morphology of all the nymphal stages of these species is described and illustrated, and identification keys are provided to each instar. The results show that nymphal stages can be used to accurately identify soft scale insect species.
对软蚧（半翅目：蚧总科：蚧科）种的确定依赖于雌性成虫形态，这带来了几个问题。本文对来自土耳其安卡拉地区和以色列的软蚧科（软蚧亚科）的各种若虫期进行了研究，包括：Eulecanium cerasorum（Cockerell）、E. ciliatum（Douglas）、E. tiliae（Linnaeus）、Paleolecanium bituberculatum（Signoret）、Physokermes piceae（Schrank）和Rhodoccus perornatus（Cockerell & Parrott）。描述并图示了这些物种所有若虫期的形态，并提供了各龄期的鉴别特征。结果表明，若虫期可用于准确鉴定软蚧种。
