A laboratory milling device for improving stored grain management has been developed by Agricultural Research Service (ARS) scientists and an industry cooperator. The system, called the "insect-o-graph," can detect internal insects in wheat that are not visible to the eye or that cannot be detected by usual grading methods. The device, built by National Manufacturing, Inc. (NMI), of Lincoln, Neb., was based on ARS-developed technology. ARS engineers Tom Pearson and Dan Brabec, in the...

With bed bugs reemerging as a nuisance in some parts of the country, scientists are reporting the first preliminary description of the bug's sialome "” the saliva proteins that are the secret to Cimex lectularius' ability to suck blood from its human victims and escape to bite again with risking a lethal slap. The findings, which could have medical applications in diagnosing bed bug bites and preventing the itch, appear in ACS' monthly Journal of Proteome Research. In the report, Jose...

Researchers look for small control organism "The small size of an alien insect that feeds on a native tree from the western Pacific island of Guam allows it to hide in cracks and other locations that are out of reach for its only local natural enemy," said UOG entomologist Aubrey Moore. Moore has teamed up with UOG ecologist Thomas Marler to study the relationship between the native cycad tree, known as "fadang" in the Chamorro language, and a minute alien insect pest called cycad aulacaspis...

Insects may have tiny brains the size of a pinhead, but the latest research from the University of Adelaide shows just how clever they really are. For the first time, researchers from the University's Discipline of Physiology have worked out how insects judge the speed of moving objects. It appears that insect brain cells have additional mechanisms which can calculate how to make a controlled landing on a flower or reach a food source. This ability only works in a natural setting. In a paper...

Moth also triggers the plants into increased frequency of reproduction When a plant endemic to several islands in the Western Pacific Ocean taps the services of a helpful insect, a double-dose of benefits comes its way. The plant is a member of a unique group of plants known as cycads, which produce their seeds in cones rather than within fruits. The insect is a tiny moth currently known to exist only on the islands of Guam and Rota. The insect's primary role is to ensure seed production...

Scientists in Brazil are reporting for the first time that coffee beans contain proteins that can kill insects and might be developed into new insecticides for protecting food crops against destructive pests. Their study, which suggests a new use for one of the most important tropical crops in the world, appears in ACS' Journal of Agricultural and Food Chemistry, a bi-weekly publication. Peas, beans and some other plant seeds contain proteins, called globulins, which ward off insects. Coffee...

Agricultural Research Service (ARS) scientists are tapping into the biochemistry of one of the world's most damaging insect pests to develop a biocontrol agent that may keep the pest away from gardens and farms. Aphids spread diseases that cost gardeners and farmers hundreds of millions of dollars each year. Some of the insecticides available are not environmentally friendly, and because aphids are developing insecticide resistance, some growers are being forced to use more of the chemicals....

UC Riverside biologists say young male crickets grow larger in the presence of sexually mature adult male crickets In the animal kingdom, sexual signals often are manifested as displays of bright coloration or, in the case of crickets, as loud song. Adult male crickets produce loud song to attract females, but the song, which permeates the environment, can be overheard also by unintended receivers - such as young males unable to produce song due to a mutation they carry. Until now researchers...

It makes your skin crawl"”a bug that crawls onto your lips while you sleep, drawn by the exhaled carbon dioxide, numbs your skin, bites, then gorges on your blood. And if that's not insult enough, it promptly defecates on the wound-and passes on a potentially deadly disease. Now Jean-Paul Paluzzi, a PhD candidate in biology at the University of Toronto Mississauga, believes that manipulating physiology to prevent the insects from leaving their messy calling card represents the best hope...

The hair-like structures used by birch caterpillars to communicate warnings may have evolved from walking, researchers from Carleton University in Ottawa, Canada have discovered. The research team, led by Dr. Jayne Yack from the university, published their findings in the Nature Communications journal. Their report was entitled "The evolutionary origins of ritualized acoustic signals in caterpillars" and was published in the April 12 issue. In the abstract accompanying their report, the...

Leaf Insects, Phylliidae
2014-08-05 10:01:39

Phylliidae is a family of insects most commonly known as leaf insects or walking leaves, which can be found in Southeast Asia and South Asia to Australia. Although it is classified as a family, there is no general agreement on its classification, as many suggest that the family is actually a large taxon that should contain separate families of leaf insects. It is thought that this family has changed little over long periods of time, due to fossil evidence found of a forty-seven million year...

Tetragnatha extensa
2013-10-09 13:17:36

Tetragnatha extensa is a species of spider found across the Northern Hemisphere. It has an elongate body, up to .43 inches long, and assumes a straight line posture when it is alarmed. It lives on low vegetation in damp areas and consumes flying insects which it catches in its web. This spider has a stretched out, cream colored body. The males are smaller than the females at around .35 inches body length, compared to .43 inches in the females. The four pairs of legs are long and a dark...

The yellow-tipped tigertail (Choristhemis flavoterminata) is species of dragonfly that is native to Queensland, Australia. This species prefers to reside in warm, moist habitats near bodies of water like rivers. The yellow-tipped tigertail reaches an average body length of 1.8 inches and holds a long, thin abdomen. The end of the body holds a bright yellow spot and the wings are light brown in color with a brown spot. Larvae are described as slightly hairy and are light brown or gray in...

Wandering Glider, Pantala flavescens

The wandering glider (Pantala flavescens), also known as the globe skimmer, is a species of dragonfly that can be found in a large range that includes Easter Island and Europe, although it is rare here, but it typically occurs in tropical and subtropical areas as well as cooler areas like Northern Canada, depending upon the season. This species has been recorded flying at heights of 20,341 feet in the Himalayas, higher than any other dragonfly species. The wandering glider reaches an...

The gray sanddragon (Progomphus borealis) is a species of dragonfly that can be found in many areas including Arizona, California, Idaho, Texas, New Mexico, Washington, and the U.S. Virgin Islands. This species prefers a habitat near streams and rivers in desert climates. It is typically seen between the months of June and September, but it can also be seen between April and October. Adult gray sanddragons reach an average body length between 2.2 and 2.4 inches, while its nymphs or larvae...
