Remarks
- Systematics: Subfamily: Coccinae A, Coccini (Choi & Lee, 2019) Coccus pseudomagnoliarum is similar to C. gymnospori (Green) and C. hesperidum but differs in lacking submarginal tubercles and tibio-tarsal articulatory scleroses (which are present in the latter 2 species). (Kondo, Watson & Gavrilov-Zimin, 2022)
- Structure: Adult female elongate oval, slightly convex, up to 7 mm long; dorsum of young female grey with dark brown mottling, while dark grey in older ones. In life greenish or greyish, with light or dark yellow mottling; dermal areolations present; dorsal tubercles absent; dorsal tubular ducts absent; dorsal setae with sharply pointed apices; marginal setae with simple pointed or spatulate apices; multilocular disc-pores usually with 6–10 loculi; ventral tubular ducts with a narrow inner ductule, few present on submaginal area of posterior abdomen; antennae each 8-segmented; legs without tibio-tarsal articulatory scleroses. (Choi & Lee, 2018) Color photograph in Kawai (1980, Figs. 6.13, a,b,c), Gill (1988), Tranfaglia & Viggiani (1988) Katsoyannos (1996).
- Biology: Develops one annual generation in California (Quayle, 1915), Israel (Ben-Dov, 1980), Greece (Argyriou & Ioanides, 1975), Australia (Smith et al., 1997). Females reproduce parthenogenetically. Usually found on leaf undersides along midveins and twigs. (Kondo, Watson & Gavrilov-Zimin, 2022)
- Economic Importance: Natural enemies listed by Borchsenius (1957). Has been a serious pest, in the early 1900's, of citrus in USA, Arizona and California (Quayle, 1938; Ebeling, 1959; Kennett, 1988). But became less injurious in the 1940's following the application of DDT and other synthetic insecticides. It economic importance increased during the 1980's - 1990's, because these insecticides lost effectiveness (Trumble et al. 1995). Kennett (1988) reported on exploration for parasitoids in Japan. Dreistadt (1996) studied the scale during 1991-1994 in USA, California and found that its populations increased in comparison to previous years; the citricola scale was 5-25 times more abundant than Parthenolecanium corni, P. pruinosum and P. cerasorum; three control measures of the citricola scale were evaluated. Trumble et al. (1995) has developed in USA, California a binomial (presence-absence) sampling plan, which was validated for infestations of the citricola scale on orange trees. A minor pest of citrus in Israel (Ben-Dov, 1980), Italy (Longo & Russo, 1986) and Australia (Smith et al., 1997). Rugman, et al. (2010) presents a simple, quick and accurate method to identify any life stage of the ten major parasitoids of soft scales in California citrus, based on amplification of ribosomal DNA, using the polymerase chain reaction (PCR).
- General Remarks: Description and illustration of the adult female given by De Lotto (1973a) (as C. aegaeus), Tranfaglia (1974) (as C. aegaeus), Gill et al. (1977), Gill (1988) and by Kosztarab (1996). Description of the adult female, first-instar nymph and female second-instar nymph given by Borchsenius (1957).
