Gerard LeBlond for redOrbit.com - Your Universe Online Scientist from Yale University studied the extinct pterygotid eurypterid, a giant sea scorpion, the largest arthropod that ever lived. It was always believed to be a fierce predator, but a recent study revealed that may not have been the case. The paper titled, “What big eyes you have: The ecological role of giant pterygotid eurypterids,” is published in the journal Biology Letters. Ross Anderson, a Yale graduate student and...

USDA The spread of damaging invasive forest pests is only partially powered by the insects’ own wings. People moving firewood for camping can hasten and widen the insects’ spread and resulting forest destruction. A new U.S. Forest Service study gives state planners a tool for anticipating the most likely route of human-assisted spread they can use to enhance survey and public education efforts. The study, “Using a Network Model to Assess Risk of Forest Pest Spread via...

RESCUE!® fly traps are proven summer solutions for nuisance or filth flies. Spokane, WA (PRWEB) July 08, 2014 Flies are common, annoying and unsanitary. But they’re more than just a nuisance. They’re carriers of filth and more than 60 human and animal diseases. With temperatures warming, experts warn that hot, humid conditions create ideal environments for flies to breed and develop. “The warmer the weather, the faster the flies are produced,” says Dr. Qing-He Zhang, Ph.D.,...

[ Watch The Video: Plants Respond To Leaf Vibrations Caused By Insects’ Chewing ] University of Missouri-Columbia Previous studies have suggested that plant growth can be influenced by sound and that plants respond to wind and touch. Now, researchers at the University of Missouri, in a collaboration that brings together audio and chemical analysis, have determined that plants respond to the sounds that caterpillars make when eating plants and that the plants respond with more...

Gene Silencing Technology Alters Sex Of Prawns
2014-07-01 03:28:58

Society for Experimental Biology Israeli scientists have developed a novel method for generating single-sex populations of prawns. This could be used to boost the productivity of aquaculture farms and even as a biocontrol measure against invasive species and pests. Male sexual differentiation in crustaceans is regulated by the androgenic gland. It is thought that this overrides a default program of female differentiation, allowing male features to develop. This comes from the...

Bloodsucking Parasite Threatens UK Honeybees
2014-06-27 03:23:24

Biotechnology and Biological Sciences Research Council Scientists have discovered how a bloodsucking parasite has transformed Deformed Wing Virus (DWV) into one of the biggest threats facing UK honeybees. Honeybees are a key pollinating insect, adding around $40Bn globally to crop value. Over recent years the spread of parasites and the viruses they transmit has resulted in high overwintering colony losses. New and emerging threats to insect pollinators are putting increasing...

Theridiidae is a family that contains over 2,200 species of cobweb spiders, also known as tangle-web spiders or comb-footed spiders, which can be found throughout the world. This species received its common names from its tendency to build three dimensional, sticky webs and from the comb of serrated bristles on the fourth leg. It is thought that this family is the only to hold a high diversity of web types, including gumfooted webs, which are highly similar to those produced by spiders in the...

Agelenidae is a family that holds about 1,200 recognized species of funnel weaver spiders that occur throughout the world. These spiders build funnel shaped webs that trap prey in their complicated patterns, but they should not be confused with other families of spiders that build funnel webs like funnel-web spiders or funnel-web tarantulas. Funnel weavers can reach an average body length between .1 inches in the smallest species and .7 inches, although the largest species can reach total...

Thomisidae is a family that holds around two thousand species of crab spiders that can be found throughout the world. Although the name crab spider has been used to refer to a large number of species, it is most often used to refer to members of this family, especially the flower crab spider. Many members of this family have flat bodies that resemble those of crabs and others hold their two front legs in positions that crabs are known for or move in sideways motions as crabs do. Although...

Jumping Spiders, Salticidae
