Scientists at The University of Manchester have found evidence of the genetic basis of the evolutionary arms-race between parasitoids and their aphid hosts. The researchers studied the reaction of aphids when a parasitic wasp with genetic variation laid eggs in them. They found that different genotypes of the wasp affected where the aphids went to die, including whether they left the plant host entirely. The team also found an example of the emergence of a shared phenotype that was partly...

In August 2011, researchers from the U.S. Department of Agriculture were presented with a serious, and potentially very costly, puzzle in Kennewick, Wash. Since Kennewick lies within a region near the heart of Washington state's $1.5 billion apple-growing region, an annual survey of fruit trees is performed by the Washington State Department of Agriculture (WSDA) to look for any invading insects. This time the surveyors discovered a crabapple tree that had been infested by a fruit fly that...

(PRWEB) March 08, 2013 Leading Maryland, Virginia and District of Columbia pest control company Affordable Pest, LLC, issues a warning to consumers to prepare for larger brown marmorated stink bug populations in the coming spring. “The Department of Agriculture and Virginia Tech research is...

New Moth Perfumes Generated Through Genetic Mutations
2013-02-20 11:05:21

April Flowers for redOrbit.com - Your Universe Online A new study led by scientists at Sweden´s Lund University has revealed that a single mutation in a moth gene can produce an entirely new scent. The research team believes the results could contribute to the tailored production of pheromones that could be used for pest control. The scent of a female moth can be picked up by the male from several hundred feet away.  The males are guided by sexual pheromones —...

A new discovery promises to allow expanded use of a mainstay biological pest control method, which avoids the health, environmental and pest-resistance concerns of traditional insecticides, scientists are reporting. The advance toward broadening applicability of the so-called sterile insect technique (SIT) appears in the journal ACS Synthetic Biology. Luke Alphey and colleagues explain that the Lepidoptera, a large family of insects with a caterpillar stage, cause widespread damage...

Asian Needle Ants Displacing Other Aggressive Invaders
2013-02-11 10:07:43

North Carolina State University Researchers from North Carolina State University have found that one of the most aggressive invasive ant species in the United States — the Argentine ant — appears to have met its match in the Asian needle ant. Specifically, the researchers have found that the Asian needle ant is successfully displacing Argentine ants in an urban environment, indicating that the Asian needle ant — with its venomous sting — may be the next invasive...

Red Locust, Nomadacris septemfasciata
2013-07-10 15:41:21

The red locust (Nomadacris septemfasciata) is a species of grasshopper that is native to Sub-Saharan Africa, where it prefers to swarm moist areas like seasonal floodplains. It can be found in areas with grain, its main food source, and areas with some tree cover. Adults are typically brownish-tan in color and can reach an average body length between 2.4 and 3.3 inches depending upon the sex, with females growing larger. Young individuals of this species can vary in color depending upon which...

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. Larvae are often called cutworms and feed on a variety of plants of which they "cut" pieces and carry them back to their burrows for food. Adult...

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...
