Remarks

Systematics: The binomen Aspidiotus curcumae is a nomen nudum that is placed as a 'synonym' of Aspidiella hartii. The nomen nudum has been published by Kasargode (1914: 134), Fletcher (1919: 232), Ramakrishna Ayyar (1920a: 326), Ramakrishna Ayyar (1930), Ferris (1941e: 42), Borchsenius (1966: 376) and Kotikal & Kulkarmi (2000: 52).
Aspidiella hartii resembles A. sacchari but the species differ as follows (condition of A. sacchari in parentheses): body subcircular to broadly pyriform (more elongate pyriform); basal scleroses of median lobes parallel and poorly developed (scleroses convergent and well developed); pygidial margin weakly crenulate (more strongly crenulate); margin anterior to 3rd lobe with some simple plates (without any plates); and 3rd lobe pointed or absent (low sclerotized swelling on margin). (Watson & Kondo, 2022a)
Structure: Scale of the female brownish with pale center, circular, quite flat; that of the male similar in color, oval (Ferris, 1938a). The females have a brownish to pinkish subcircular scale, with subcentral to submarginal exuvia lighter than the rest of the dorsal shield. Faintly yellow membranous living adult females inhabit these scale covers.The male is oval and pinkish with marginal exuvia. Slide mounted adult females have two pairs of sclerotized lobes, with the third lobe represented by a small subconical tip. (Salerno, et al., 2018)
Biology: Occurring on the tubers (Ferris, 1938a). There is a record of Aspidiella hartii on Tripsacum laxum (Poaceae) but this could be a misidentification of A. sacchari, which is common on grasses. (Watson & Kondo, 2022a)
Economic Importance: The yam scale is a tropicopolitan species (see CABI, 1966, and Distribution) is a pest of yams of the genus Dioscorea, in the field and particularly of yams in storage (Schmutterer et al., 1957; Williams & Watson, 1988; Chua & Wood, 1990; Morse et al., 2000). The pest reproduces during storage and covers the tuber. Removal of plant sap shrivels the tubers during their trade, reducing quality, viability and marketability of the product. Severe A. hartii infestation of tubers can also inhibit their resprouting or kill the plant in the country of origin. Dipping yam in concentrated pyrethroids, or organophosphate insecticide, storage in sawdust, paddy husk or wood ash or paraffin wax coating may help to control the pest, although dipping in pyrethroids or organophosphate insecticide is not allowed in Europe. (Solerno, et al., 2018)
General Remarks: Description and illustration of adult female by Ferris (1938a), Balachowsky (1958b), Williams & Watson (1988) and by Colon-Ferrer & Medina-Gaud (1998).
