Eastern marsh helleborine mimics aphid alarm pheromones to attract pollinators Even Darwin was a self-admitted orchid lover. Dictionaries describe orchids as exotic ornamentals. Indeed, these plants "“ more than 30000 different species are thought to exist "“ are exotic due their extraordinary and diverse flower morphology. However, they are also exotic from a point of view other than beauty: as crafty imposters in order to achieve reproduction and to make sure that their ovaries...

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...

FREDERICK, Md., July 12 /PRNewswire/ -- American gardeners face frustrating problems with their edible or ornamental gardens. These problems are caused by many different pests. Here are MasterGardening.com's Top 10 garden pests and control tips: 1. Deer. These peaceful animals were tabbed as causing the most widespread damage in a USDA national survey. Clean up all unharvested fruits and vegetables. If you still see signs of deer damage -- torn leaves or bark scraped off trees -- you can...

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....

These insect pests pioneered new frontiers in genetics Contrary to popular belief, aphids are not just sap-sucking, plant-destroying enemies of agriculture. In fact, these pests are genetic pioneers that evolved two unique traits, according to a study that appears in the April 30 issue of the journal Science. First, aphids are, so far, the only animal known to produce essential pigments known as carotenoids. The aphid's pigment-producing ability is unique to the animal kingdom. Other...

University of Illinois researchers recently identified a new soybean aphid biotype that can multiply on aphid-resistant soybean varieties. Soybean aphids are the No. 1 insect threat to soybean production in the North Central region of the United States. Last year, aphid infestation on soybean was high enough that many growers had to spray their fields to control aphids. Despite this, many aphids survived and took flight last fall causing a public nuisance. Migrating soybean aphids have...

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....

Aphids could be considered the "mosquitoes" of the plant world, depending on the "blood" of plants to survive. They live in symbiosis with bacteria that pass from one generation to the next, producing essential amino acids. Aphids with the same genotype can be wingless or winged. In different seasons, they develop as asexual females who produce offspring with identical genes through parthenogenesis. When temperatures drop, they can give birth to males who then fertilize the eggs laid by...

A common plant virus lures aphids to infected plants by making the plants more attractive, but when the insects taste the plant, they quickly leave for tastier, healthier ones. In the process, the insects rapidly transmit the disease, according to Penn State entomologists. "The virus improves the cues that insects use to identify food by elevating some aspect of a trait that is already in the plant," said Mark C. Mescher, assistant professor of entomology. "In this case they appear to elevate...

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...
