Young Galactic supernova remnants (SNRs) are where we can observe closely supernova (SN) ejecta and their interaction with the circumstellar/interstellar medium. They also provide an opportunity to explore the explosion and the final stage of the evolution of massive stars. Near-infrared (NIR) emission lines in SNRs mostly originate from shocked dense material. In shocked SN ejecta, forbidden lines from heavy ions are prominent, while in shocked circumstellar/interstellar medium, [Fe II] and H2 lines are prominent. [Fe II] lines are strong in both media, and therefore [Fe II] line images provide a good starting point for the NIR study of SNRs. There are about twenty SNRs detected in [Fe II] lines, some of which have been studied in NIR spectroscopy. We will review the NIR [Fe II] observations of SNRs and introduce our recent NIR spectroscopic study of the young core-collapse SNR Cas A where we detected strong [P II] lines.

 ,  , The Indian wax scale, Ceroplastes ceriferus (Fabricius) is redescribed so that it can be distinguished from Ceroplastes pseudoceriferus Green, which it most nearly resembles and has been confused with in Korea. A dichotomous key, photographs, and DNA barcode information are also presented for identifying three Ceroplastes species from Korea.

The legless mealybug, Antonina nakaharai Williams and Miller (Hemiptera: Pseudococcidae) is recorded from bamboos (Poaceae) in Korea. An identification key to adult females of three species of Antonina from the Korean Peninsula is also provided.
