  • Systematics: The recent synonymy of Aonidiella narainus and A. azadirachti with A. orientalis is based on examination of the type series of A. narainus and all available material of A. azadirachti at the Natural History Museum(NHM)by Gillian W. Watson and Benjamin Normark. (Normark, et al., 2014)
  • Structure: As it occurs on coconut the scale of the female is quite thick, flat, circular, ranging in color from almost white to a very light brown, exuviae central, the second exuvia dark brown. Scale of the male slightly elongate oval, the yellowish exuvia near one end (Ferris, 1938a).Scale of female roughly circular, 1.44 mm long, 1.2 mm wide, flat, pinkish or light brown with subcentrally first and second larval exuviae (Dutta & Singh, 1990). first-instar nymph body oval and broadest in thoracic region. Anterior margin is undulated and sclerotized. Dorsal side is feebly convex and ventral side somewhat flat. The average of each length and width of the crawler 0.247mm and 0.147mm. Yellowish green in color. (Singh Ojha & Singh, 2019)
  • Biology: Occurring usually upon the foliage (Ferris, 1938a). Aonidiella orientalis reproduces sexually; adult females probably produce species-specific sex pheromone to attract adult males. Parthenogenetic and viviparous forms of reproduction were also observed. Aonidiella orientalis can have from three generations (in India) up to six generations (in Australia) each year. (EFSA2021) Females and males develop through four life stages: an egg, two larval instars and an adult. The larval instars of males are called pre-pupa and pupa. Adult males have wings and females are wingless. (EFSA2021)
  • Economic Importance: The oriental red scale is a highly polyphagous scale insect (see Host Plants) and widely distributed in tropical and subtropical (CABI, 1978b, and see Distribution). It has been recorded as a pest of several agricultural crops: Citrus (Rose, 1990c); Tea (Nagarkatti & Sankaran, 1990); date palm, India (Glover, 1933; Rajagopal & Krishnamoorty, 1996); date palms, Saudi Arabia (Hammad et al., 1981; Moussa, 1986); palms and ornamentals, Florida (Dekle, 1976); papaya, Queensland, Australia (Elder et al., 1998); mango, Israel (Ben-Dov & Wysoki, 1990; Swirski et al., 2002).
