Latest Aphid Stories
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.
A new study has found the mating behaviors of various insects change to avoid making themselves vulnerable during inclement weather.
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.
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.
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.
According to new research, when a carnivore becomes extinct, other predatory species could soon tag along.
The yellow meadow ant, Lasius flavus, farms root aphids for sugar (honeydew) and nitrogen (protein).
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.
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.
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.
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...
