Parlatoria Blanchardi
''Parlatoria blanchardi'', the date palm scale, is a species of armored scale insect in the family Diaspididae. It is a widespread and serious pest of palms, both date palms and ornamental species. Description The adult female test is an elongated oval shape, and is whitish, with a pale brown raised area with a darker brown or blackish central area. Underneath the scale, the insect is nearly circular, pink at first, changing to yellowish-brown when mature. The male test is whitish and also elongate oval, but is smaller than the female's test. Males can be winged or wingless, but females never have wings. Distribution ''Parlatoria blanchardi'' is thought to originate from Mesopotamia but has spread to many other tropical and subtropical regions. It occurs in North Africa, Saudi Arabia, France, Spain, Italy, Palestine, Jordan, Syria, Turkey, Afghanistan, Iran, Iraq, Turkmenistan, Pakistan and India.

Species
In biology, a species is the basic unit of classification and a taxonomic rank of an organism, as well as a unit of biodiversity. A species is often defined as the largest group of organisms in which any two individuals of the appropriate sexes or mating types can produce fertile offspring, typically by sexual reproduction. Other ways of defining species include their karyotype, DNA sequence, morphology, behaviour or ecological niche. In addition, paleontologists use the concept of the chronospecies since fossil reproduction cannot be examined. The most recent rigorous estimate for the total number of species of eukaryotes is between 8 and 8.7 million. However, only about 14% of these had been described by 2011. All species (except viruses) are given a two-part name, a "binomial". The first part of a binomial is the genus to which the species belongs. The second part is called the specific name or the specific epithet (in botanical nomenclature, also sometimes i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Latania
''Latania'', commonly known as latan palm or latania palm, is a genus of flowering plant in the palm tree family, native to the Mascarene Islands in the western Indian Ocean. Species The genus contains three species, one from each of the three major islands (including islets) in the chain. All species have been ranked as Endangered by the IUCN. Latan palms are large, single-stemmed fan palms with separate male and female plants (dioecy); when the leaves fall, they leave scars on the trunks. Male flowers are small, in clusters, and emerge from within leathery bracts on the catkin-like inflorescence An inflorescence is a group or cluster of flowers arranged on a stem that is composed of a main branch or a complicated arrangement of branches. Morphologically, it is the modified part of the shoot of seed plants where flowers are formed o ...s. Female flowers are larger, solitary and not concealed within bracts.

Vinca Major
''Vinca major'', with the common names bigleaf periwinkle, large periwinkle, greater periwinkle and blue periwinkle, is a species of flowering plant in the family Apocynaceae, native to the western Mediterranean.

Pritchardia
The genus ''Pritchardia'' (family Arecaceae) consists of between 24 and 40 species of fan palms (subfamily Coryphoideae) found on tropical Pacific Ocean islands in Fiji, Samoa, Tonga, Tuamotus, and most diversely in Hawaii. The generic name honors William Thomas Pritchard (1829-1907), a British consul at Fiji. Description These palms vary in height, ranging from .

Date Palm
''Phoenix dactylifera'', commonly known as date or date palm, is a flowering plant species in the palm family, Arecaceae, cultivated for its edible sweet fruit called dates. The species is widely cultivated across northern Africa, the Middle East, and South Asia, and is naturalized in many tropical and subtropical regions worldwide.

Diaspididae
Diaspididae is the largest family of scale insects with over 2650 described species in around 400 genera. As with all scale insects, the female produces a waxy protective scale beneath which it feeds on its host plant. Diaspidid scales are far more substantial than those of most other families, incorporating the exuviae from the first two nymphal instars and sometimes faecal matter and fragments of the host plant. These can be complex and extremely waterproof structures rather resembling a suit of armor. For this reason these insects are commonly referred to as armored scale insects. As it is so robust and firmly attached to the host plant, the scale often persists long after the insect has died. Some African Diaspididae are attended by ants of genus ''Melissotarsus''. The ants appear to consume the armored scales because Diaspididae are completely naked when ant-attended; the ant nest itself remains completely hidden under the bark of the tree.
