Systematics: Unruh & Gullan (2008b) included this species in the “Icerya aegyptiaca group” which includes two species, i.e., I. aegyptiaca and I. schrottkyi. The adult females of both species have pores on the derm that resemble the vulvar pores, but SI. schrottkyi possesses unique hexalocular pores on the ventral surface that are absent from all other iceryine species. The two species can be separated easily by the number of cicatrices on the venter of the adult female (one in I. aegyptiaca, three in I. schrottkyi). (Kondo, et al., 2016)
Structure: Female entirely covered by a mass of thick, white curled or undulated threads. On dorsum four tall, thick tufts of white wax, two or three of which are inclined towards anterior end, and the remainder towards the posterior end. Ovisac very large, wider than body, and is composed of fine, white, glossy, felted threads (Hempel, 1920a).
Economic Importance: Icerya schrottkyi is considered a pest of grapevines in Brazil.
General Remarks: Description and illustration of adult female by Hempel (1900a, 1920a), Vayssiere (1929) and by Foldi & Soria (1989). Description of adult female by Unruh & Gullan (2008b).
