Ülgentürk, S. 2003 A scanning electron microscope study of the multilocular disc-pores of some adult female soft scale insects (Hemiptera: Sternorrhyncha: Coccidae).. Phytoparasitica 31(4): 393-398.

Notes: The morphology of the multilocular disc-pores of nine species of Coccidae (Anapulvinaria pistaciae, Coccus hesperidum, C. pseudomagnoliarum, Eulecanium ciliatum, E. tiliae, Filippia follicularis, Parthenolecanium corni, P. rufulum and Rhodococcus perornatus) were examined using a scanning electron microscope. The spiracular disc-pores of seven of these species had five loculi in an outer ring around a central, closed loculus, but the central loculus of E. tiliae and F. follicularis was open. The preanal disc-pores had 6-12 (usually 10) loculi in the outer ring but the structure of the central loculus varied among species, with that of A. pistaciae and F. follicularis being mushroom-shaped; of C. hesperidum, C. pseudomagnoliarum, P. corni and P. rufulum being peg- or tongue-shaped; and of E. ciliatum, E. tiliae and R. perornatus having a vertical slit.
