Alien Ladybug In Europe Dropping Native Species Population
2012-02-07 12:24:40

An alien predator in Europe is leading to a rapid decline of a native ladybugs in Britain, Belgium and Switzerland. Scientists have found that Harlequin ladybugs are overwhelming native ladybugs through predation and competition. The native ladybug, most known for the 2-spots on its back, have declined by 30 percent in Belgium and 44 percent in Britain over the past five years after the Harlequin species arrived in 2001. "This study provides strong evidence of a link between the...

CSIRO research has revealed that the tremendous diversity of ladybird beetle species is linked to their ability to produce larvae which, with impunity, poach members of "Ëœherds' of tiny, soft-bodied scale insects from under the noses of the aggressive ants that tend them. Reconstructing the evolutionary history of ladybird beetles (family Coccinellidae), the researchers found that the ladybirds' first major evolutionary shift was from feeding on hard-bodied ("armoured") scale...

When plant-eating mammals such as goats chomp on a sprig of alfalfa, they could easily gobble up some extra protein in the form of insects that happen to get in their way. But a new report in the August 10th issue of Current Biology, a Cell Press publication, shows that plant-dwelling pea aphids have a strategy designed to help them avoid that dismal fate: The insects sense mammalian breath and simply drop to the ground. "Tiny insects like aphids are not helpless when facing large animals...

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...

Research entomologist Louis Hesler takes readers along as he and others search for types of ladybugs that were once common but have become extremely rare in eastern North America I was frustrated. I had been searching for years for the so-called "lost ladybugs," but hadn't found any. It was 2008, and only a few had been found by anyone in the last three decades, although they were once common in many areas, especially crop fields such as wheat and alfalfa. There are actually hundreds of kinds...

RIVERSIDE, Calif. "“ The Galapagos Islands, made famous by Charles Darwin, have a unique biota now highly threatened by invasive species because of increased tourism and population growth. Indeed, alien or exotic insects today constitute 23 percent of the Galapagos insect fauna. One of these insect invaders is the cottony cushion scale, a sap sucking bug native to Australia. Capable of infesting many woody ornamentals and crops, the cottony cushion scale decreases the vitality of its...

Forget top-to-bottom only. New Cornell University evolutionary biology research shows how plants at the bottom of the food chain have evolved mechanisms that influence ecosystem dynamics as well. (Science, March 26, 2010.) "The ecology and interactions of most organisms is dictated by their evolutionary history," said Anurag Agrawal, associate professor of ecology and evolutionary biology (EEB), the study's senior author. In food webs, predators help suppress populations of prey by eating...

Findings could be useful in development of pest-resistant crops There's a war occurring each day in our backyards "“ plant versus plant-eating insect versus insect-eating insect. Research by UC Irvine's Kailen Mooney suggests the outcome "“ of interest to farmers "“ is a stalemate. For a study published online Friday, March 26, in the journal Science, Mooney and colleagues studied 16 species of milkweed, a group of flowering plants found throughout the Western hemisphere....

University of Montreal researcher studies odd insect behavior Are ladybugs being overtaken by wasps? A Universit© de Montr©al entomologist is investigating a type of wasp (Dinocampus coccinellae) present in Quebec that forces ladybugs (Coccinella maculata) to carry their larvae. These wasps lay their eggs on the ladybug's body, a common practice in the insect world, yet they don't kill their host. "What is fascinating is that the ladybug is partially paralyzed by the parasite, yet...

The control of spider mites, which damage tree leaves, reduce fruit quality and cost growers millions of dollars in the use of pesticide and oil spraying, is being biologically controlled in Pennsylvania apple orchards with two tiny insects known to be natural predators, according to Penn State researchers. "Spider mites feed on the chlorophyll in the cells of leaves, damaging their ability to use photosynthesis," said David Biddinger, tree fruit entomologist and biocontrol specialist at the...

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...

Cucujiformia is an infraorder of Polyphagan beetles, representing the vast majority of plant eating beetles. The infraorder contains six superfamilies: Lymexylidae (ship-timber beetles) Cleroidea (checkered beetles, bark-gnawing beetles and soft winged flower beetles) Cucujoidea (31 families that includes ladybirds, fungus beetles and bark beetles) Tenebrionoidea (also Heteromera) (30 families including blister beetles and ant-like beetles) Chrysomeloidea (4 families including...

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...

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...
