A new study published in the Journal of Economic Entomology shows that radiation can be used to effectively sterilize the light brown apple moth (LBAM), an insect pest found in Australia, New Zealand, California, Hawaii, Sweden, and the British Isles. The light brown apple moth, Epiphyas postvittana (Walker), feeds on apples, pears, stonefruits, citrus, grapes, berries and many other plants. A native of Australia, it has been found in California since 2007. The California Department of Food...

Scientists have developed Bt toxins for the management of Bt resistance in European corn borer and other crop pests. Toxins from Bacillus thuringiensis bacteria (Bt toxins) are used in organic and conventional farming to manage pest insects. Sprayed as pesticides or produced in genetically modified plants, Bt toxins, used in pest control since 1938, minimize herbivory in crops, such as vegetables, maize or cotton. Since 1996, Bt producing transgenic crops have been grown, which...

The creation of compounds that disrupt a worldwide pest´s winter sleep hints at the potential to develop natural and targeted controls against crop-eating insects, new research suggests. Scientists have designed agents that interfere with the protective dormancy period of the corn earworm, a species that infests more than 100 types of plants and costs American farmers an estimated $2 billion a year in losses and control costs. The compounds, composed of synthetic molecules that...

Non-native, wood-boring insects such as the emerald ash borer and the Asian longhorned beetle are costing an estimated $1.7 billion in local government expenditures and approximately $830 million in lost residential property values every year, according to study by a research team that included scientists with the U.S. Forest Service, Northern Research Station. The research effort was funded by The Nature Conservancy and supported by the University of California / Santa Barbara's National...

Invasive Insects Cost Billions

  Homeowners and taxpayers are picking up most of the tab for damages caused by invasive tree-feeding insects that are inadvertently imported along with packing materials, live plants, and other goods. That's the conclusion of a team of biologists and economists, whose research findings are reported in the journal PLoS One last week. The authors explain that non-native, wood-boring insects such as the emerald ash borer and the Asian longhorned beetle exact an estimated $1.7...

A six-year campaign to control invasive winter moths with a natural parasite led by entomologist Joe Elkinton of the University of Massachusetts Amherst now has concrete evidence that a parasitic fly, Cyzenis albicans, has been established and is attacking the pest at four sites in Seekonk, Hingham, Falmouth and Wellesley. It´s the beginning of the end for the decade-long defoliation of eastern Massachusetts trees by the invasive species, Elkinton says. The researchers marked an...

Wood-Boring Pest Now in Neighboring States, Could Threaten Hardwoods Industry ROCK SPRINGS, Pa., Aug. 16, 2011 /PRNewswire-USNewswire/ -- Agriculture Secretary George Greig today asked the public to help keep the Asian Longhorned Beetle from entering the state, saying the non-native, invasive wood-boring pest could severely harm Pennsylvania's $25 billion hardwoods industry. "The Asian Longhorned Beetle has not yet been found in Pennsylvania, but if it is allowed to enter it could pose a...

The Agrotis infusa or Bogong moth is a species of nocturnal moth that in spring will swarm in great numbers around public buildings in Canberra, Australia. They are commonly found in Southern parts of Australia featuring a wingspan of one and three quarters inches and are brown or black in color with stout bodies covered with long thick scales.

The Codling Moth (Cydia pomonella), is a member of the Lepidopteran family Tortricidae. They are known as an agricultural pest, their larva being the common apple worm. It is originally native to Europe but was introduced to North America, where it has become one of the regular pests of apple orchards. Now it is found nearly worldwide. It also is a pest against pears, walnuts, and other tree fruits. The codling moth is grayish with light gray and copper stripes on its wings, and has an...

PHOTO CAPTION: Goliath Beetle Beetles are one of the main groups of insects. Their order, Coleoptera (meaning "sheathed wing"), has more species than any other order in the entire animal kingdom. Forty percent of all described insect species are beetles (about 350,000 species), and new species are regularly discovered. Estimates put the total number of species at between 5 and 8 million. When J. B. S. Haldane, a British geneticist, was asked what his studies of nature revealed about...

The gypsy moth, Lymantria dispar, is a moth of European origin. Life cycle Gypsy moth egg masses are laid on branches and trunks of trees, however egg masses may be found in any sheltered location. Egg masses are buff colored when first laid but may bleach out over the winter months when exposed to direct sunlight and weathering. The hatching of gypsy moth eggs coincides with budding of most hardwood trees. Larvae emerge from egg masses from early spring through mid-May. Larvae...
