Frontiers The open-access journal Frontiers in Ecology and Evolution reports the first known case where four species, all at different levels in the food chain, use a single odor to communicate with and ruthlessly exploit each other. Plant-feeding insects are often attracted to odors that are released by damaged plant tissue because these plants are already under attack and so a good place to look for food, sexual partners, and egg-laying sites. The jumping plant louse Diaphorina citri...

Insects Avoid Mating In Bad Weather
2013-10-03 09:47:25

Brett Smith for redOrbit.com - Your Universe Online From a slight pain in the back to carefully observing the behavior of birds or cows, people have always been looking for signs of an impending storm. Now, a new study in the journal PLOS ONE has indicated the mating behaviors of various insects change in order avoid making themselves vulnerable during inclement weather. The study researchers hypothesized some bugs exhibit a decrease in their mating habits to lower their exposure to...

Invasive Ladybugs Use Biological Warfare On Native Species
2013-05-17 14:49:56

Brett Smith for redOrbit.com - Your Universe Online German researchers have uncovered another cautionary tale about the importation of a species that quickly becomes an invasive threat. Introduced to Europe and North America for the purpose of controlling pesky greenhouse aphids, the Asian lady beetle escaped into the ecosystem and quickly dominated the local ladybug population. According to a new report in the journal Science, the aggressive ladybug´s dominance is being assisted...

Diet Of The Lady Beetle Influences Its Effectiveness As Biocontrol Agent

U.S. Department of Agriculture (USDA) By examining what lady beetles eat, U.S. Department of Agriculture (USDA) scientists are learning more about the movement of these beneficial insects in farm fields–and whether they'll actively feed on crop pests. Agricultural Research Service (ARS) entomologist Jonathan Lundgren at the agency's North Central Agricultural Research Laboratory in Brookings, S.D., and former ARS entomologist Michael Seagraves were part of a team of ARS and...

How Bacteria Came To Live Inside Insects

University of Utah Symbiotic microbes' origin discovered after man impales hand on branch Two years ago, a 71-year-old Indiana man impaled his hand on a branch after cutting down a dead crab apple tree, causing an infection that led University of Utah scientists to discover a new bacterium and solve a mystery about how bacteria came to live inside insects. Because the new bacterial strain is easy to grow in the laboratory and is related to Sodalis, a genus of bacteria that lives...

One Extinction Leads To Another

redOrbit Staff & Wire Reports - Your Universe Online According to new research, when a carnivore becomes extinct, other predatory species could soon tag along. Other scientists have previously submitted this theory, but a University of Exeter team has now carried out the first experimentation to authenticate it. According to lead researcher Dr Frank van Veen of the University of Exeter's Centre for Ecology and Conservation, "Our experiment provides the first proof of something that...

Root Aphid Cloned By Ant Farms In Subterranean Rooms
2012-07-02 08:21:28

The yellow meadow ant, Lasius flavus, farms root aphids for sugar (honeydew) and nitrogen (protein). In turn these species of aphids have developed distinctive traits never found in free living species such as the 'trophobiotic organ' to hold honey dew for the ants. New research published in BioMed Central's open access journal BMC Evolutionary Biology shows that over half of ant mounds contained only one of the three most common species of aphid, and two thirds of these has a single aphid...

UK Asks Protestors Not To Destroy Genetically Modified Wheat Fields

Image Credit: Photos.com --- Brett Smith for Redorbit.com Agricultural researchers in the UK made a plea to environmental protesters on Tuesday in an attempt to dissuade them from carrying out threats to destroy experimental genetically modified (GM) wheat. A protest movement called Take the Flour Back has called for a “decontamination” of an experimental wheat field just north of London that was planted by Rothamsted Research, a publicly funded agricultural research...

Aphids are pests that cause millions of pounds of damage to crops in the UK, but new research led by biologists at the University of York reveals potential new targets for aphid-specific insecticides. Because it lives exclusively on the sugary sap of plants, aphids´ diet is limited in nitrogenous essential amino acids. To solve this problem, the aphid must use a bacterial symbiont, Buchnera, that lives inside special insect cells and supplements the animal´s diet with the...

Cunning Super-parasitic Wasps Sniff Out Protected Aphids And Overwhelm Their Defenses
2012-02-23 18:00:20

In the war between parasite and host, the parasitic wasp, Aphidius ervi, and the pea aphid, Acyrthosiphon pisum, are locked in a battle for survival. New research published in BioMed Central's open access journal BMC Biology shows that this cunning parasite sniffs out differences between protected and unprotected aphids, and alters its egg-laying strategy, in order to overwhelm aphid defenses and ensure survival of wasp offspring. The wasp, A. ervi, lays an egg inside the pea aphid, where...

Aphids or greenfly, plant lice (superfamily Aphidoidea) are small plant-feeding insects (1 to 10 mm). Of the 4,000 species of known aphids (distributed in 10 families), around 250 are serious pests for agriculture and forestry as well as an annoyance for gardeners. Natural predators include ladybirds, hoverfly larvae and lacewings. Aphids have two compound eyes and two ocular tubercles made up of 3 lenses, each of which is located behind and above the compound eyes. They have 2 tarsal...

The soldier beetles (Cantharidae) are relatively soft-bodied, straight-sided beetles. They are closely related to the Lampyridae, or firefly family. Some are important predators of aphids during their brief adulthood.

Flower-flies (also known as hover-flies) are a family of flies (Diptera), with the scientific name of "Syrphidae". As their names suggests, they are most often seen around flowers. The adults feed mainly on nectar and pollen, while the larvae (maggots) eat a wide range of foods. In certain species, the larvae are saprophytes, eating decaying plant and animal matter in the soil or in ponds and streams. In others, the larvae are insectivores and prey on aphids, thrips, and other...

Ladybirds, also known as ladybugs or lady beetles are a family, Coccinellidae ("little sphere"), of beetles. The name is thought to allude to the Blessed Virgin Mary in the Catholic faith. Ladybirds are found worldwide, with over 4,500 species described - more than 450 native to North America alone. Ladybirds are small insects, ranging from 1 mm to 10 mm (0.04 to 0.4 inches), and are usually yellow, orange, or red with small black spots on their carapace, and black legs, head and feelers. As...
