picture info	Coccidae The Coccidae are a family of scale insects belonging to the superfamily Coccoidea. They are commonly known as soft scales, wax scales or tortoise scales. The females are flat with elongated oval bodies and a smooth integument which may be covered with wax. In some genera they possess legs but in others, they do not, and the antennae may be shortened or missing. The males may be winged or wingless. Genera There are >1,100 spp. in 171 genera worldwide.

	Saissetia Coffeae ''Saissetia coffeae'', known generally as hemispherical scale, is a species of soft scale insect in the family Coccidae. Other common names include the helmet scale and coffee brown scale. Description The adult scale varies in diameter from about to , largely depending on the identity of the host plant. It is smooth, shiny and brown and closely adpressed to a stem or leaf, resembling a miniature military helmet. Young scales often have a slightly ridged surface, sometimes in the form of a "H". Like other scale insects, the hemispherical scale has no limbs and is immobile, piercing the plant tissues with its mouthparts and feeding on sap. Distribution ''Saissetia coffeae'' is present in West, Central and East Africa, Madagascar, tropical and subtropical Asia, North, Central and South America and the Caribbean region. Life cycle All hemispherical scale insects are female, and breeding occurs by parthenogenesis. The eggs are pinkish-beige, oblong and about long. Up to a thousand ...

	Saissetia Oleae ''Saissetia oleae'' ( syn. ''Coccus oleae'') is a scale insect in the family Coccidae. It is considered one of the three main phytophagous parasites of the olive tree (''Olea europaea''), together with the olive fruit fly (''Bactrocera oleae'') and the olive moth ('' Prays oleae''). Although it is a common parasite which occurs most often in olive trees, it is a polyphagous species, also attacking (but less frequently) citrus trees as well as various ornamental shrubs such as oleanders, pittosporums, sago palm, and euonymus. History One of the first scientists who studied the insect in a scientific and modern way was Italian naturalist Giuseppe Maria Giovene. He wrote a publication entitled ''Descrizione e storia della cocciniglia dell'ulivo'' (1807) in which he answered Giovanni Presta who had denied the existence of the insect in the Apulian provinces of Bari and Otranto. Giovene showed that the insect was common in the above regions as well, even though it occurred less ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu]
picture info	Sternorrhyncha Genera The Sternorrhyncha suborder of the Hemiptera contains the aphids, whiteflies, and scale insects, groups which were traditionally included in the now-obsolete order "Homoptera". "Sternorrhyncha" refers to the rearward position of the mouthparts relative to the head. Distributed worldwide, all members of this group are plant-feeders, many considered pests feeding on major crops and ornamental plants. Many exhibit modified morphology and/or life cycles, including phenomena such as flightless morphs, parthenogenesis, sexual dimorphism, and eusociality. Phylogeny The phylogeny of the extant Sternorrhyncha, inferred from analysis of small subunit (18S) ribosomal RNA, is shown in the cladogram. The evolutionary position of several fossil taxa are unclear. A suggested phylogeny is: Groups Well-known groups in the Sternorrhyncha include: * aphids – (Aphididae) * woolly and gall-making aphids (Eriosomatinae) * pine and spruce aphids (Adelgidae) * phylloxerans (Phylloxeridae, i ...
