Having the right bacteria can be a lifesaver for an aphid. Having the wrong bacteria, or no bacteria at all, could be a recipe for becoming wasp fodder. Pea aphids vary in their resistance to parasitoid wasps, which scientists 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 within the aphids, according to new research.

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) has found that special proteins change shape in the plants when they are stressed to protect them. Aphid's saliva can overcome their defence mechanism because it contains a substance which prevents this shape change. The protein's ability to change shape is being investigated further as a potential component in nanomotor...

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...

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...
