First Report of Scale Insects (Hemiptera: Diaspididae: Lepidosaphes pallida (Maskell) on Russian Arborvitae (Pinales: Cupressaceae: Microbiota Decussata Kom.)

A sample of a Russian arborvitae experiencing leaf browning and branch dieback was submitted to the Penn State University (PSU) Plant Disease Clinic on 23 May 2019 and it was determined that the damage was caused by phomopsis twig blight (Figs. 1, 2). The sample also hosted a scale insect infestation, so was forwarded to the PSU Insect Identification Laboratory on 12 June. The scales were suspected to be Maskell scales (Lepidosaphes pallida (Maskell, 1895)) based on the gestalt of the tests and coniferous host (Fig. 3) and that identity was confirmed by comparing slide-mounted specimens to the description and illustrations provided by Miller and Davidson (2005).
