Leptocybe Invasa (blue Gum Chalcid) Gall On Eucalyptus
''Leptocybe invasa'', the blue gum chalcid wasp or eucalyptus gall wasp, is a chalcid wasp which is the only species in the monotypic genus ''Leptocybe'' in the subfamily Tetrastichinae, of the family Eulophidae. It is a gall wasp which causes the formation of galls on a number of species of ''Eucalyptus'', it was described in 2004 after galls were found in river red gums (''Eucalyptus camaldulensis'') in the Mediterranean and Middle East and has since been found to be a widespread species where its host trees are planted. It is indigenous to Australia. Description This tiny wasp is just over one millimeter in length. Its body is brown with a slight blue to green iridescence. Parts of the legs are yellowish in color. Distribution ''Leptocybe invasa'' is native to Queensland, Australia where its exact distribution has yet to be determined. It has now been found as an invasive species in eucalypts in northern, eastern and southern Africa, Asia, the Pacific Region, Europe as far no ...

Chalcid Wasp
Chalcid wasps (, , for their metallic colour) are insects within the superfamily Chalcidoidea, part of the order Hymenoptera. The superfamily contains some 22,500 known species, and an estimated total diversity of more than 500,000 species, meaning the vast majority have yet to be discovered and described. The name "chalcid" is often confused with the name "chalcidid", though the latter refers strictly to one constituent family, the Chalcididae, rather than the superfamily as a whole; accordingly, most recent publications (e.g.,) use the name "chalcidoid" when referring to members of the superfamily. Most chalcid wasps are parasitoids of other insects, though other life styles are known, with the herbivorous fig wasps acting as pollinators. Various species are used as biological pest control agents or in scientific research. Description Chalcidoids are generally small wasps, averaging 1.5 mm in length and usually being less than 3 mm. The body is often metallic in colour. Th ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Eucalyptus Gunnii
''Eucalyptus gunnii'', commonly known as cider gum, is a species of small to medium-sized tree endemic to the island of Tasmania, Australia. It has mostly smooth bark, lance-shaped to egg-shaped adult leaves, flower buds in groups of three, white flowers and cylindrical to barrel-shaped fruit. Description ''Eucalyptus gunnii'' is a tree that typically grows to a height of and forms a lignotuber. It has smooth, mottled, white or grey bark, sometimes with persistent rough bark on the lower trunk. Young plants and coppice regrowth have sessile leaves arranged in opposite pairs. Juvenile stems can be rounded or square in cross section. The juvenile leaves are heart-shaped to more or less round, greyish green or glaucous, long and wide. Adult leaves are arranged alternately, lance-shaped to egg-shaped, the same dull greyish to bluish green on both sides, long and wide on a petiole long. The flowers are arranged in leaf axils in groups of three on an unbranched peduncle l ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Israel
Israel (; he, יִשְׂרָאֵל, ; ar, إِسْرَائِيل, ), officially the State of Israel ( he, מְדִינַת יִשְׂרָאֵל, label=none, translit=Medīnat Yīsrāʾēl; ), is a country in Western Asia. It is situated on the southeastern shore of the Mediterranean Sea and the northern shore of the Red Sea, and shares borders with Lebanon to the north, Syria to the northeast, Jordan to the east, and Egypt to the southwest. Israel also is bordered by the Palestinian territories of the West Bank and the Gaza Strip to the east and west, respectively. Tel Aviv is the economic and technological center of the country, while its seat of government is in its proclaimed capital of Jerusalem, although Israeli sovereignty over East Jerusalem is unrecognized internationally. The land held by present-day Israel witnessed some of the earliest human occupations outside Africa and was among the earliest known sites of agriculture. It was inhabited by the Canaanites ...

China
China, officially the People's Republic of China (PRC), is a country in East Asia. It is the world's most populous country, with a population exceeding 1.4 billion, slightly ahead of India. China spans the equivalent of five time zones and borders fourteen countries by land, the most of any country in the world, tied with Russia. Covering an area of approximately , it is the world's third largest country by total land area. The country consists of 22 provinces, five autonomous regions, four municipalities, and two Special Administrative Regions (Hong Kong and Macau). The national capital is Beijing, and the most populous city and financial center is Shanghai. Modern Chinese trace their origins to a cradle of civilization in the fertile basin of the Yellow River in the North China Plain. The semi-legendary Xia dynasty in the 21st century BCE and the well-attested Shang and Zhou dynasties developed a bureaucratic political system to serve hereditary monarchies, or dyna ...

Biological Control
Biological control or biocontrol is a method of controlling pests, such as insects, mites, weeds, and plant diseases, using other organisms. It relies on predation, parasitism, herbivory, or other natural mechanisms, but typically also involves an active human management role. It can be an important component of integrated pest management (IPM) programs. There are three basic strategies for biological pest control: classical (importation), where a natural enemy of a pest is introduced in the hope of achieving control; inductive (augmentation), in which a large population of natural enemies are administered for quick pest control; and inoculative (conservation), in which measures are taken to maintain natural enemies through regular reestablishment. Natural enemies of insect pests, also known as biological control agents, include predators, parasitoids, pathogens, and competitors. Biological control agents of plant diseases are most often referred to as antagonists. Biologic ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Eucalyptus Tereticornis
''Eucalyptus tereticornis'', commonly known as forest red gum, blue gum or red irongum, is a species of tree that is native to eastern Australia and southern New Guinea. It has smooth bark, lance-shaped to curved adult leaves, flower buds in groups of seven, nine or eleven, white flowers and hemispherical fruit. Description ''Eucalyptus tereticornis'' is a tree that typically grows to a height of and forms a lignotuber.

Thereafter, limbs are unusually steeply inclined for a ''Eucalyptus'' species. The bark is shed in irregular sheets, resulting in a smooth trunk surface coloured in patches of white, grey and blue, corresponding to areas that shed their bark at different times. Young plants and coppice regrowth have dull bluish green, egg-shaped leaves that are long and wide. Adult leaves are the same shade of green on both sides, lance-shaped to curved, ...
