Carrying the right bacterial hitchhiker can make the difference between life and death for an aphid. Pea aphids are often under attack by wasps seeking to lay their eggs inside aphids, turning them into an all-you-can-eat buffet for the larval wasps. The aphids vary in their resistance to the wasps, which scientists had chalked up to genetic differences between aphids. But it's not in their genes at all -- the wasp-resistant aphids owe their lives to the symbiotic bacteria carried inside...

Aphids salivate at the thought of beans! In fact, if it weren't for their saliva they would starve to death. Professor Aart van Bel (Justus-Liebig-Universität, Germany) will be speaking at the Society for Experimental Biology Annual Main Meeting in Barcelona, on Thursday 14th July [session P2.1] about how special dynamic proteins are involved in 'plant rescue systems' and how aphid's saliva can overcome their defence mechanism. Bean plants contain contractile protein bodies (forisomes)...

TOLEDO, Ohio (AP) -- Farmers are bracing for what researchers predict will be the return of an insect that attacks soybeans in the Midwest, where most of the crop is grown. For now, farmers must decide whether it makes sense to spray for soybean aphids before the insects emerge. Some say they will wait until they know whether their fields have been infested. Others aren't taking chances. "All of the research points to this being the year for aphids," said Allen Armstrong, who plans on...

WACO, Texas (AP) -- Swarms of Asian lady bugs, introduced in this country to control pests, have themselves become a nuisance on golf courses and in homes and gardens around Texas. The insects are beneficial in the summer, but in the winter they infest houses - unlike native lady bugs, which prefer to stay outdoors. Agriculture experts say the Asian bugs deposit waste and shed skins that become allergens inside homes. They can also leave blood stains on curtains and clothes. "You hate to...

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 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...
