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. [1]
Gypsy moth eggs are frequently found during border biosecurity checks, commonly on used vehicles, and were first discovered in the 1990s. [2]
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. [3] Health concerns were raised, but a report to the Ministry of Health concluded that there were no grounds for the concerns. [4] In 2004, The Ministry of Agriculture and Forestry declined Hamilton's Fraser High School's compensation claim for the cost of relief teachers to cover staff absences during the operation. [5]
Lymantria dispar, also known as the gypsy moth or the spongy moth, is a species of moth in the family Erebidae. Lymantria dispar is subdivided into several subspecies, with subspecies such as L. d. dispar and L. d. japonica being clearly identifiable without ambiguity. Lymantria dispar has been introduced to several continents and is now found in Europe, Africa, Asia, North America and South America. The polyphagous larvae live on a variety of deciduous and coniferous trees and can cause severe damage in years of mass reproduction. Due to these features, Lymantria dispar is listed among the world's 100 worst invasive alien species.
Aerial application, or what is informally referred to as crop dusting, involves spraying crops with crop protection products from an agricultural aircraft. Planting certain types of seed are also included in aerial application. The specific spreading of fertilizer is also known as aerial topdressing in some countries. Many countries have severely limited aerial application of pesticides and other products because of environmental and public health hazards like spray drift; most notably, the European Union banned it outright with a few highly restricted exceptions in 2009, effectively ending the practice in all member states.
Fraser High School (FHS) is a secondary school in Hamilton, New Zealand. The school began in 1920 as Hamilton Technical Day School.
Calosoma sycophanta, the forest caterpillar hunter, is a species of ground beetle belonging to the family Carabidae.
The California Department of Food and Agriculture (CDFA) is a cabinet-level agency in the government of California. Established in 1919 by the California State Legislature and signed into law by Governor William Stephens, the Department of Food and Agriculture is responsible for ensuring the state's food safety, the protection of the state's agriculture from invasive species, and promoting the California agricultural industry.
Mating disruption (MD) is a pest management technique designed to control certain insect pests by introducing artificial stimuli that confuse the individuals and disrupt mate localization and/or courtship, thus preventing mating and blocking the reproductive cycle. It usually involves the use of synthetic sex pheromones, although other approaches, such as interfering with vibrational communication, are also being developed.
The light brown apple moth is a leafroller moth belonging to the lepidopteran family Tortricidae. The moth was confirmed to be present in mainland United States in 2007, principally along the West Coast. The State of California and the US Department of Agriculture quickly imposed quarantine measures and decided to use aerial spraying of cities with pesticides to try to eradicate the moth. This led to substantial public controversy and claims of adverse health effects. Aerial spraying was discontinued in 2008. Trapping, monitoring, and inspection efforts were reduced or eliminated in 2012 due to budget problems.
Wilding conifers, also known as wilding pines, are invasive trees in the high country of New Zealand. Millions of dollars are spent on controlling their spread.
Glyptapanteles is a genus of endoparasitoid wasps found in Central and North America and New Zealand. The larvae of the members of Glyptapanteles sp. are distinguished by their ability to manipulate their hosts into serving as bodyguards.
There is a high use of pesticides in New Zealand due predominantly to the large agricultural industry.
The gypsy moth, 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 painted apple moth is an invasive species that was eradicated from New Zealand.
Biosecurity in New Zealand guards against threats to agriculture and biodiversity, with strict border control measures being taken to prevent unwanted organisms from entering the country. New Zealand is an island nation that is geographically isolated from any other significant landmass. The species that are present evolved in the absence of organisms from elsewhere and display a high degree of endemism. Notable is the lack of land-based mammals, except for two species of bat. Indigenous species are at risk from population decline or extinction if any invasive species are introduced.
This is a list of notable events relating to the environment in 2003. They relate to environmental law, conservation, environmentalism and environmental issues.
Plant Protection and Quarantine (PPQ) is one of six operational program units within the Animal and Plant Health Inspection Service (APHIS) of the United States Department of Agriculture (USDA). The PPQ works to safeguard agriculture and natural resources in the U.S. against the entry, establishment, and spread of animal and plant pests, and noxious weeds in order to help ensure an abundant, high-quality, and varied food supply.
Lymantria dispar asiatica, the LDA moth or Asian spongy moth, also known as the Asian gypsy moth, is a moth in the family Erebidae of Eurasian origin. It is similar to Lymantria dispar dispar in appearance, but adult females can fly. It is classified as a pest and is host to over 500 species of trees, shrubs and plants.
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.
Lymantria dispar japonica, also known as the Japanese gypsy moth or Japanese spongy moth, is a moth in the family Erebidae of Eurasian origin.
Lymantria dispar multicapsid nuclear polyhedrosis virus or LdMNPV is a viral infection in spongy moths that causes infected larvae to die and disintegrate. Infected larvae climb to the top of a tree and die. The larvae then melt or disintegrate, falling onto the foliage below, where they infect more larvae.
John Douglas Tothill DSc, CMG, was an English-born entomologist, agriculturalist and civil servant, whose career took him to Canada, Fiji, Uganda and the Sudan. He was the son of Walter Tothill and Frances L. Williams.
