Life cycle ''Hoplocampa flava'' is known to nest in the flowerbuds of plum, cherry plum, cherry, apricot, or sloe. Adults will plant eggs in the buds, following the hatch the larvae burrow into the developing fruits because of this the fruits secrete a oozy ...

Mediterranean
The Mediterranean Sea is a sea connected to the Atlantic Ocean, surrounded by the Mediterranean Basin and almost completely enclosed by land: on the north by Western and Southern Europe and Anatolia, on the south by North Africa, and on the east by the Levant. The Sea has played a central role in the history of Western civilization. Geological evidence indicates that around 5.9 million years ago, the Mediterranean was cut off from the Atlantic and was partly or completely desiccated over a period of some 600,000 years during the Messinian salinity crisis before being refilled by the Zanclean flood about 5.3 million years ago. The Mediterranean Sea covers an area of about , representing 0.7% of the global ocean surface, but its connection to the Atlantic via the Strait of Gibraltar—the narrow strait that connects the Atlantic Ocean to the Mediterranean Sea and separates the Iberian Peninsula in Europe from Morocco in Africa—is only wide.

Europe
Europe is a large peninsula conventionally considered a continent in its own right because of its great physical size and the weight of its history and traditions.

Caucasus
The Caucasus () or Caucasia (), is a region between the Black Sea and the Caspian Sea, mainly comprising Armenia, Azerbaijan, Georgia, and parts of Southern Russia.

Mount Elbrus in Russia, Europe's highest mountain, is situated in the Western Caucasus. On the southern side, the Lesser Caucasus includes the Javakheti Plateau and the Armenian highlands, part of which is in Turkey. The Caucasus is divided into the North Caucasus and South Caucasus, although the Western Caucasus also exists as a distinct geographic space within the North Caucasus. The Greater Caucasus mountain range in the north is mostly shared by Russia and Georgia as well as the northernmost parts of Azerbaijan. The Lesser Caucasus mountain range in the south is occupied by several independent states, mostly by Armenia, Azerbaijan, and Georgia, but also ...

Prolegs
A proleg is a small, fleshy, stub structure found on the ventral surface of the abdomen of most larval forms of insects of the order Lepidoptera, though they can also be found on other larval insects such as sawflies and a few other types of insects. In all the orders in which they appear, mainly Hymenoptera and Lepidoptera, prolegs of any form evolved independently of each other by convergent evolution. Prolegs of lepidopteran larvae have a small circle of gripping hooks, called "crochets". The arrangement of the crochets can be helpful in identification to family level. Although the point has been debated, prolegs are not widely regarded as true legs, derived from the primitive uniramous limbs. Certainly in their morphology they are not jointed, and so lack the five segments (coxa, trochanter, femur, tibia, tarsus) of thoracic insect legs. Prolegs do have limited musculature, but much of their movement is hydraulically Hydraulics (from Greek: Υδραυλική) is a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Plum
A plum is a fruit of some species in ''Prunus'' subg. ''Prunus''''.'' Dried plums are called prunes. History Plums may have been one of the first fruits domesticated by humans. Three of the most abundantly cultivated species are not found in the wild, only around human settlements: ''Prunus domestica'' has been traced to East European and Caucasian mountains, while ''Prunus salicina'' and '' Prunus simonii'' originated in China. Plum remains have been found in Neolithic age archaeological sites along with olives, grapes and figs. According to Ken Albala, plums originated in Iran. They were brought to Britain from Asia. An article on plum tree cultivation in Andalusia (southern Spain) appears in Ibn al-'Awwam's 12th-century agricultural work, ''Book on Agriculture''. Etymology and names The name plum derived from Old English ''plume'' "plum, plum tree", borrowed from Germanic or Middle Dutch, derived from Latin ' and ultimately from Ancient Greek ''proumnon'', itself belie ...

Cherry
A cherry is the fruit of many plants of the genus ''Prunus'', and is a fleshy drupe (stone fruit). Commercial cherries are obtained from cultivars of several species, such as the sweet ''Prunus avium'' and the sour ''Prunus cerasus''. The name 'cherry' also refers to the cherry tree and its wood, and is sometimes applied to almonds and visually similar flowering trees in the genus ''Prunus'', as in " ornamental cherry" or "cherry blossom". Wild cherry may refer to any of the cherry species growing outside cultivation, although ''Prunus avium'' is often referred to specifically by the name "wild cherry" in the British Isles. Botany True cherries ''Prunus'' subg. ''Cerasus'' contains species that are typically called cherries. They are known as true cherries and distinguished by having a single winter bud per axil, by having the flowers in small corymbs or umbels of several together (occasionally solitary, e.g. ''P. serrula''; some species with short racemes, e.g. '' P. ...

Apricot
An apricot (, ) is a fruit, or the tree that bears the fruit, of several species in the genus ''Prunus''. Usually, an apricot is from the species '' P. armeniaca'', but the fruits of the other species in ''Prunus'' sect. ''Armeniaca'' are also called apricots. Etymology ''Apricot'' first appeared in English in the 16th century as ''abrecock'' from the Middle French ''aubercot'' or later ''abricot'', from Spanish '' albaricoque'' and Catalan ''a(l)bercoc'', in turn from Arabic الْبَرْقُوق (al-barqūq, "the plums"), from Byzantine Greek βερικοκκίᾱ (berikokkíā, "apricot tree"), derived from late Greek ''πραικόκιον'' (''praikókion'', "apricot") from Latin '' ersica ("peach")praecocia'' (''praecoquus'', "early ripening"). Species Apricots are species belonging to ''Prunus'' sect. ''Armeniaca''. The taxonomic position of '' P. brigantina'' is disputed. It is grouped with plum species according to chloroplast DNA sequences, but more closely r ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
