Survey of scale insects of ornamental plants in Alexandria Governorate, Egypt.
This investigation covers a survey of the scale insects associating with some ornamental plants at three chosen public gardens as well as at the experimental farm of the Agricultural Research Station in Alexandria Governorate, Egypt. A total of nineteen scale insect species belonging to sixteen genera related to four families of the super-family Coccoidea were found infesting eighteen ornamental plants during the period from April, 1998 up to March, 1999. These species are: Family: Asterolecaniidae--Represented by one species only The fig scale Russelaspis pustulans; (Cockerell) = (Asterolecanium pustulans Cock). Family: Coccidae--Represented by the seven species Florida wax scale. Ceroplastes floridensis Comstock, Green shield scale. Chloropulvinaria psidii (Maskell), Long brown scale. Caccus elongatus (Douglas), Brown soft scale Coccus hesperidum (Linn.), Tessellated scale. Eucalymnatus tessellatus (Signoret), Hemispherical scale. Saissetia coffeae (Walker), and Olive soft scale. Saissetia oleae (Olivier) Family: Diaspididae--Represented by the ten species: Oleander scale. Aspidiotus hederae (Vallot), Minute cypress scale. Carulaspis minima (Targioni-Tozzetti), Dictyosprmum scale Chrysomphalus dictyospermi (Morgan), Palm fiorinia scale. Fiorinia fioriniae (Targioni), Latania scale Hemiberlisia lataniae (Signoret), Fig scale. Lepidosaphes ficus (Signoret), Snow scale. Lineaspis striata (Newstead), Masked scale. Mycetaspis personata (Comstock), Olive scale. Parlatoria oleae (Colvee), and White peach scale Pseudaulacaspis pentagona (Targioni-Tozzetti), Family: Eriococcidae--Represented by one species only Eriococcus araucariae (Maskell).
