Nipponaclerda biwakoensis is a scale insect originally described from Japan, and naturally occurring in China; in these countries it is most often associated with reeds in the genus Phragmites.[1] This species has become established (as of 2017) in the United States in the state of Louisiana, where it has rapidly become a serious pest of roseau cane, damaging over 80% of the reeds in some areas such as the Pass a Loutre Wildlife Management Area,[2] where it is referred to by the older common name Phragmites scale insect or the more recently-coined name, roseau cane mealybug.[3] Several species of parasitoid wasps are known to attack this scale,[1] with initial investigations focusing on the species Neastymachus japonicus, known only to attack this one pest.[2]
While Phragmites is often considered a noxious weed,[4] in Louisiana the reed beds, dubbed "roseau cane", are critical to the stability of the shorelines of wetland areas and waterways of the Mississippi Delta, and the die-off of reed beds is believed to accelerate coastal erosion.[2]

Nipponaclerda biwakoensis (лат.) — вид полужесткокрылых насекомых-червецов рода Nipponaclerda из семейства аклердиды (Aclerdidae)[1][2]..
Восточная Азия: Китай и Япония[1].
Самки имеют удлинённо-овальную форму, длина от 2,3 до 7,0 мм, ног и усиков нет Щетинки анального кольца развиты слабо, тонкие и короткие, по длине они значительно уступают размерам анальной пластинки и поэтому сверху почти незаметны[3]. Питаются соками таких растений, как Juncaceae (Juncus); Poaceae (Agropyron, Phragmites communis). Среди врагов паразитические наездники Encyrtidae (Astymachus japonicus; Boucekiella depressa; Platencyrtus aclerus); Eulophidae (Aprostocetus). Вид был впервые описан в 1907 году энтомологом С. Куваной (Kuwana, S. I. )[2][4][5][6]. Таксон Nipponaclerda biwakoensis включён в состав рода Nipponaclerda вместе с таксонами Nipponaclerda leptodermis, Nipponaclerda triumpha, Nipponaclerda turanica[1][2][7].
