Researchers Use Plant-produced Sex Pheromone To Trap Moths
2014-02-27 14:24:45

Kansas State University A collaborative experiment involving a Kansas State University biochemist may mark the beginning of an effective, environmentally friendly plant-based method of insect control. Timothy Durrett, assistant professor of biochemistry and molecular biophysics, was part of the collaboration that used various plant and moth enzymes to engineer plants that emitted sex pheromones that mimic those naturally produced by two species of moths. The research recently...

But will stink bugs emerge from hibernation early? Experts at RESCUE! explain. Spokane, WA (PRWEB) February 05, 2014 Famed groundhog Punxsutawney Phil woke up from hibernation on Sunday, saw his shadow, and as legend goes, retreated back to his burrow for six more weeks of winter slumber. But what does this mean for insects that wake up from hibernation indoors? Unfortunately, once hibernating stink bugs wake up, they don’t go back to sleep like Phil. When the stored-up food in their...

Wasps Used To Fight Citrus Greening Disease Are Unlikely To Threaten Non-target Insects
2014-02-04 08:35:10

Entomological Society of America In August 2008 the Asian citrus psyllid (Diaphorina citri), an invasive insect known to spread citrus greening disease (huanglongbing), which can be lethal to citrus trees, was detected in southern California. After initial treatments with insecticides were determined to be costly and unsustainable, a decision was made to instead try biological control by using insect parasitoids that are known to attack the psyllids. However, since the only known...

The Moth Versus The Crowd
2014-01-24 10:46:18

Centre for Ecology & Hydrology An army of citizen scientists has helped the professionals understand how a tiny 'alien' moth is attacking the UK's conker (horse-chestnut) trees, and showed that naturally-occurring pest controlling wasps are not able to restrict the moth's impact. The study's conclusions are published this week in the open access scientific journal PLOS ONE. No bigger than a grain of rice, the horse-chestnut leaf-mining moth has spread rapidly through England and...

How Did The Desert Locust Lose Its Memory?
2014-01-14 10:59:40

Ciência Viva The desert locust (a type of grasshopper), much like Dr Jekyll/Mr Hyde, goes from being an innocuous solitary-living individual to become a voracious gregarious animal that destroys everything on its path (and back). These two very different “personas” are remarkable adaptations of a single genome to distinct environments. But apparently, this flexibility is even more impressive says Patricio Simōes, Jeremy Niven and Swidbert Ott from the Champalimaud Neuroscience...

Novel Attract-and-kill Approach Developed To Target Argentine Ants
2014-01-06 13:15:08

University of California - Riverside UC Riverside entomologists devise a technique that involves mixing a synthetic pheromone in insecticide sprays After being inadvertently introduced in the United States from South America, Argentine ants have successfully invaded urban, agricultural, and natural settings nationwide. In urban California, the Argentine ant is among the primary pest ants. For example, this particular species of ants makes up 85 percent of ants sampled by commercial pest...

New Study Could Help Rearing Of Stink Bugs For Biological Control
2014-01-05 07:13:10

Entomological Society of America Many people think of stink bugs as pests, especially as the brown marmorated stink bugs spreads throughout the U.S. However, certain stink bugs are beneficial, such as Podisus nigrispinus (Dallas), a predatory stink bug that is considered an important biological control agent for various insect pests of cotton, soybean, tomato, corn, kale, and other crops. Now a new study appearing in Annals of the Entomological Society of America called "Effect of Egg...

Viruses alter plant biochemistry in order to manipulate visiting aphids into spreading infection University of Cambridge researchers have shown that viruses use aphids as pawns, discouraging the insects from permanently settling on already-infected crops and using this forced migration to spread infection to healthy vegetation. Aphids are sap-sucking insects that attack many different types of plants and are major transmitters of crop-infecting viruses. By altering plant biochemistry,...

Corn that contains proteins that protect it from insect damage has been grown in the U.S. since the mid-1990s. Known as Bt corn, because the proteins are derived from a bacterium called Bacillus thuringiensis, these plants have been widely grown by farmers. While Bt corn has been highly effective against the European corn borer, it has been less so against the western corn rootworm, which has been documented to show resistance to the Bt proteins. In a new article in the Journal of...

Research Into Desert Locusts Discovers How Your Environment Shapes Your Thinking
2013-11-21 13:12:19

University of Leicester A team of scientists has shown how the environment shapes learning and memory by training locusts like Pavlov's dog to associate different smells with reward or punishment. Desert locusts are notorious for their devastating swarms. However, they do not always live in swarms — they switch between a lone living 'solitary phase' and a swarming 'gregarious' phase. The two phases differ profoundly in looks, behavior and in their life style. The new research from...

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...
