Carotenoids are one of the primary factors in an aphid’s color. Recent research has found that the aphids’ color, and carotenoid production, changes depending on environmental factors. Colder temperatures result in greener aphids with high levels of carotenoids, optimal conditions bred orange aphids with medium levels of carotenoids, and oppressive, limited environments bred white, pigment-less aphids.
Pea aphids are small and green or pink
Aphids are already recognized as different from most animals in that they produce their own carotenoids- pigments that are generated by plants, microorganisms and fungi. Though the ability was originally attributed to a gene swap between the bugs and fungi, new information implies that the substance is related to the aphid’s photosynthetic abilities.

At first glance the pea aphid looks like your average insect. Little, green, and something your mother curses in the garden. Recent sequencing of its genome (The International Aphid Genomics Consortium 2010) has revealed a very different tale involving the co-evolution of two completely unrelated organisms.

Aphids represent the most important group of insect pests in agriculture in temperate Europe. They can infest a wide range of arable and horticultural crops in a very short period of time, which is why farmers are advised to treat this aphid pest problem from the very first symptom. The most widespread species in Europe are: green peach aphid , Bird cherry-oat aphid , potato aphid and Black bean aphid .
In general, aphids reduce crop yield and/or quality, which lead to significant economical losses. The major crops infected are wheat, barley, sugar beet, potatoes, lettuce, and beans. The damage caused by aphids depends on the type, for instance the black bean aphid causes damage by direct feeding whereas the green peach aphid causes the most damage by being a virus vector for more than 120 viruses (Rothamsted insect survey).
The average percentage loss caused by different aphid species is variable, ranging from 4,4% on potatoes, since these plants are rather resistant to aphids, compared to 46-43% on field beans. In 1979, aphids caused a potential economic loss of £70 x 106 in Britain. In the US, aphids have an economic impact of more than one-quarter billion dollars in an outbreak year (Larsson , 2005).
