A new, open-access article (DOI: 10.1603/PM10016) in the Journal of Integrated Pest Management describes the biology and ecology profiles of the soybean aphid (Aphis glycines Matsumura), an insect pest which can reduce soybean yields by $2.4 billion annually if left untreated.
Farmers who spray insecticides against aphids as a preventative measure only achieve a short-term effect with this method.
As soon as aphids feeding on a plant sense the heat and humidity in a mammal's breath, they drop to safety before they are inadvertently ingested together with the plant the animal is feeding on.

Nonindigenous insects and pathogens continue to become established in US forests with regularity despite regulations intended to prevent this.
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...
