Gypsy Moths In New Zealand
The gypsy moth, an invasive species from Eurasia, was discovered in New Zealand. The gypsy moth has potentially disastrous effects on New Zealand agriculture; an intensive eradication programme was planned and undertaken, and the moth did not become established. Gypsy moth eggs are frequently found during border biosecurity checks, commonly on used vehicles, and were first discovered in the 1990s. 2003 Hamilton Gypsy Moth spray In 2003 a live adult moth in viable condition was found in an early warning pheromone trap in the North Island city of Hamilton. Since Hamilton is an entry point for a large amount of international air freight it was presumed that the moth had entered New Zealand in an aircraft. An aerial pesticide spraying programme by the Ministry of Agriculture and Forestry using the Foray 48B insecticide was carried out over the city from October 2003. Health concerns were raised, but a report to the Ministry of Health concluded that there were no grounds for the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Lymantria Dispar Dispar
''Lymantria dispar dispar'' or LDD moth, commonly known as the gypsy moth, European gypsy moth, North American gypsy moth, or spongy moth, is a species of moth in the family Erebidae that is of Eurasian origin. It has a range that extends over Europe, Africa, and North America. Carl Linnaeus first described the species ''Lymantria dispar'' in 1758. The subject of classification has changed throughout the years, resulting in confusion surrounding the species' taxonomy. This caused many references to describe this one species in different ways. The family has jumped between Lymantriidae, Noctuidae and Erebidae. ''Lymantria dispar dispar'' has been designated a subspecies of ''Lymantria dispar''. It is classified as a pest, and its larvae consume the leaves of over 500 species of trees, shrubs and plants. The gypsy moth is one of the most destructive pests of hardwood trees in the Eastern United States. It is listed as one of the 100 most destructive invasive species worldwide. ...

Invasive Species
An invasive species otherwise known as an alien is an introduced organism that becomes overpopulated and harms its new environment. Although most introduced species are neutral or beneficial with respect to other species, invasive species adversely affect habitats and bioregions, causing ecological, environmental, and/or economic damage. The term can also be used for native species that become harmful to their native environment after human alterations to its food webfor example the purple sea urchin ('' Strongylocentrotus purpuratus'') which has decimated kelp forests along the northern California coast due to overharvesting of its natural predator, the California sea otter (''Enhydra lutris''). Since the 20th century, invasive species have become a serious economic, social, and environmental threat. Invasion of long-established ecosystems by organisms is a natural phenomenon, but human-facilitated introductions have greatly increased the rate, scale, and geographic range ...

New Zealand
New Zealand ( mi, Aotearoa ) is an island country in the southwestern Pacific Ocean. It consists of two main landmasses—the North Island () and the South Island ()—and over 700 smaller islands. It is the sixth-largest island country by area, covering . New Zealand is about east of Australia across the Tasman Sea and south of the islands of New Caledonia, Fiji, and Tonga. The country's varied topography and sharp mountain peaks, including the Southern Alps, owe much to tectonic uplift and volcanic eruptions. New Zealand's capital city is Wellington, and its most populous city is Auckland. The islands of New Zealand were the last large habitable land to be settled by humans. Between about 1280 and 1350, Polynesians began to settle in the islands and then developed a distinctive Māori culture. In 1642, the Dutch explorer Abel Tasman became the first European to sight and record New Zealand. In 1840, representatives of the United Kingdom and Māori chiefs ...

Agriculture In New Zealand
In New Zealand, agriculture is the largest sector of the tradable economy. The country exported NZ$46.4 billion worth of agricultural products (raw and manufactured) in the 12 months to June 2019, 79.6% of the country's total exported goods. The agriculture, forestry and fisheries sector directly contributed $12.653 billion (or 5.1%) of the national GDP in the 12 months to September 2020, and employed 143,000 people, 5.9% of New Zealand's workforce, as of the 2018 census. New Zealand is unique in being the only developed country to be totally exposed to the international markets since subsidies, tax concessions and price supports for the agricultural sector were removed in the 1980s. However, as of 2017, the New Zealand Government still provides state investment in infrastructure which supports agriculture. Pastoral farming is the major land use but there are increases in land area devoted to horticulture. New Zealand is a member of the Cairns Group, which is seeking to hav ...

Biosecurity
Biosecurity refers to measures aimed at preventing the introduction and/or spread of harmful organisms (e.g. viruses, bacteria, etc.) to animals and plants in order to minimize the risk of transmission of infectious disease. In agriculture, these measures are aimed at protecting food crops and livestock from pests, invasive species, and other organisms not conducive to the welfare of the human population. The term includes biological threats to people, including those from pandemic diseases and bioterrorism. The definition has sometimes been broadened to embrace other concepts, and it is used for different purposes in different contexts. The COVID-19 pandemic is a recent example of a threat for which biosecurity measures have been needed in all countries of the world. Background and terminology The term "biosecurity" has been defined differently by various disciplines. The term was first used by the agricultural and environmental science, environmental communities to descr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pheromone
A pheromone () is a secreted or excreted chemical factor that triggers a social response in members of the same species. Pheromones are chemicals capable of acting like hormones outside the body of the secreting individual, to affect the behavior of the receiving individuals. There are ''alarm pheromones'', ''food trail pheromones'', ''sex pheromones'', and many others that affect behavior or physiology. Pheromones are used by many organisms, from basic unicellular prokaryotes to complex multicellular eukaryotes. Their use among insects has been particularly well documented. In addition, some vertebrates, plants and ciliates communicate by using pheromones. The ecological functions and evolution of pheromones are a major topic of research in the field of chemical ecology. Background The portmanteau word "pheromone" was coined by Peter Karlson and Martin Lüscher in 1959, based on the Greek φερω ''pheroo'' ('I carry') and ὁρμων ''hormon'' ('stimulating'). Pheromones ...

Hamilton, New Zealand
Hamilton ( mi, Kirikiriroa) is an inland city in the North Island of New Zealand. Located on the banks of the Waikato River, it is the seat and most populous city of the Waikato region. With a territorial population of , it is the country's fourth most-populous city. Encompassing a land area of about , Hamilton is part of the wider Hamilton Urban Area, which also encompasses the nearby towns of Ngāruawāhia, Te Awamutu and Cambridge. In 2020, Hamilton was awarded the title of most beautiful large city in New Zealand. The area now covered by the city was originally the site of several Māori villages, including Kirikiriroa, from which the city takes its Māori name. By the time English settlers arrived, most of these villages, which sat beside the Waikato River, were abandoned as a result of the Invasion of Waikato and land confiscation (''Raupatu'') by the Crown. Initially an agricultural service centre, Hamilton now has a diverse economy and is the third fastest growin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Hamilton's Fraser High School
Fraser High School (FHS) is a secondary school in Hamilton, New Zealand. The school began in 1920 as Hamilton Technical Day School (later amended to Hamilton's Technical High School in 1924). History In 1970, the school moved to the northwest suburbs of Hamilton and was re-established as a comprehensive co-educational secondary school. In 1969 while still at the Hamilton Technical College site the school was called Fraser High School under principal Dave Campbell. The school took its name from the original Principal, Whampoa Fraser. In 1998 the name was modified slightly to Hamilton's Fraser High School to reflect their historical link to Hamilton Technical Day School, and to give a stronger geographical link to Hamilton. The Māori name of the school is ''Te Kura Tuarua o Taniwharau''. The former principal of the school, Martin Elliott, caused some controversy over his use of obscenities during his ill-fated run for the Mayoralty of Hamilton in 2004. Hamilton Fraser High Sch ...

Invasive Species In New Zealand
A number of introduced species, some of which have become invasive species, have been added to New Zealand's native flora and fauna. Both deliberate and accidental introductions have been made from the time of the first human settlement, with several waves of Polynesian people at some time before the year 1300, followed by Europeans after 1769. Almost without exception, the introduced species have been detrimental to the native flora and fauna but some, such as farmed sheep and cows and the clover upon which they feed, now form a large part of the economy of New Zealand. Registers, lists and indexes of species that are invasive, potentially invasive, or a threat to agriculture or biodiversity are maintained by Biosecurity New Zealand. Animal species Many invasive animal species are listed in schedules 5 and 6 of the Wildlife Act 1953. Those in Schedule 5 have no protection and may be killed. Those in Schedule 6 are declared to be noxious animals and subject to the Wild An ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gypsy Moths In The United States
The gypsy moth (''Lymantria dispar''), also known as the spongy moth, was introduced in 1868 into the United States by Étienne Léopold Trouvelot, a French scientist living in Medford, Massachusetts. Because native silk-spinning caterpillars were susceptible to disease, Trouvelot imported the species in order to breed a more resistant hybrid species. Some of the moths escaped, found suitable habitat, and began breeding. The gypsy moth is now a major pest of hardwood trees in the Eastern United States. The first US outbreak occurred in 1889 in the New England states. In 1923 attempts were made to prevent the westward spread of the moth by maintaining a barrier zone extending from Canada to Long Island of nearly 27,300 km2. This barrier however broke down by 1939. By 1987, the gypsy moth had established itself throughout the Northeastern United States, southern Quebec, and Ontario. The insect has now spread into Michigan, Minnesota, Virginia, West Virginia, Illinois, and Wisc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
