Insect Pests In The Making
2014-03-19 21:19:27

UC Davis Of thousands of known species of Drosophila fruit flies, just one is known as a crop pest, depositing eggs inside ripening fruit so its maggots can feed and grow. New research from the University of California, Davis, shows the similarities and crucial differences between this pest and its close relatives — and that one related fly has potential to also become a pest. Drosophila flies, found worldwide, lay their eggs in rotting fruit. Drosophila suzukii, also referred to as...

New attractant formula traps even more stink bugs with the RESCUE!® Stink Bug Trap. Spokane, WA (PRWEB) March 06, 2014 Sterling International, manufacturer of the RESCUE!® Stink Bug Trap, has received a U.S. patent (8,663,620 B2) for murgantiol as a stink bug attractant. In testing by Sterling’s scientists, murgantiol was proven to have a synergistic effect on the original attractant used in the RESCUE!® Stink Bug Trap. By adding murgantiol, a proven attractant on its...

Stink Bug Saliva Proteins Used To Control Pests
2014-02-27 15:03:37

Penn State Brown marmorated stink bugs cause millions of dollars in crop losses across the United States because of the damage their saliva does to plant tissues. Researchers at Penn State have developed methods to extract the insect saliva and identify the major protein components, which could lead to new pest control approaches. "Until now, essentially nothing was known about the composition of stink bug saliva, which is surprising given the importance of these insects as pests and...

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...

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...
