Remarks
- Structure: Young adult female almost circular, pale grey-brown in color with yellow spots at the level of the eyes, stigmatic furrows and body axis to anal plaques. Dorsum marked with a longitudinal ridge and two transverse ridges pointing towards the stigmatic furrows. (Lagowska, et al., 2018) Egg-laying female brownish. The dimension of the ovisac slightly exceeds that of the female and is for the greatest part covered by the flattened female body, which gradually rises up, adhering to the substrate only with the stylets. The infestation becomes apparent when the numerous females secrete their white ovisacs on trunk and old branches, forming large whitish patches clearly visible even from a distance. Slide-mounted adult female body subcircular, about 5.3–6.9 mm long and 4.3–6.5 mm wide, anal cleft about 1/7 of body length. Derm membranous. Dorsal submarginal tubercles absent. (Kondo, et al, 2022)
- Biology: A univoltine species in France (Canard, 1968a), southern England (Halstead, 1982; Speight & Nicol, 1984) and Germany (Sengonca & Faber, 1005, 1996). Males are rare and reproduction is mostly parthenogenetic. (Kondo, et al., 2022)
- Economic Importance: Recorded as an urban pest in London (Speight & Nicol, 1984). Kozar et al. (1994) reported that this species is widely distributed in Western Europe and causes damage to ornamentals. Sengonca & Arnold (1999) surveyed the distribution and frequency in Germany from 1996 to 1998. In spite of the unsightly appearance of the infested trees, with trunks and branches covered by thousands of ovisacs, damage is seldom apparent and is considered only aesthetic. Moreover, in contrast with other Pulvinaria species, P. regalis produces a low amount of honeydew. For these reasons control measures (mechanical methods) are rarely practised and are taken only on high-value trees. (Kondo, et al., 2022)
- General Remarks: Description and illustration of the adult female given by Danzig (1980b). Because P. regalis (considered until 2018 as P. savescui) had not been recorded after its first mention in 1982, its presence in Romania is doubtful.(Paraschiv, 2023)
