Pea Aphids are fed by the plants and crops surrounding them.

During a long period of co-evolution, plants and aphids have established a complex interaction. On the one hand, aphids have established complex life cycles involving extensive phenotype plasticity with rapid population growth (Blackman and Eastop, 1984) and a very short generation time (Morrison and Peairs, 1998). On the other hand, plants have also evolved delicate and complicated defence systems comprising constitutive defence traits and defence pathways induced upon aphid attack (Chen, 2008). Breeders and growers are still struggling to find an efficient strategy for aphid control in major crop plants, as the damage can run in the millions. The KU Leuven iGEM project has an answer to this problem. Our project consists of a genetically engineered bacteria that can reduce the aphid damage on a sustainable way by hacking into their communication system.

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.

Can photosynthesis takes place in animals? - Quora

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).

Pea aphids are a minor pest of some pulse crops, ..

The aphids generally are found on the stems and leaves of plants absorbing the sun.

How do Pea Aphids utilize photosynthesis?
Where can Pea Aphids be found?
-Pea Aphids may be found all over the world.
-Most species live in the northern and southern temperate zones where the climate is moderate.

Infestation can limit the photosynthetic activity of the plant and thus lead to a halt in growth.

which inhibits photosynthesis and can decrease plant growth.

In case of infection fungicides based on Fosetyl + Azoxystrobin Mancozeb or Copper Octanoate can be used Keep your plant dryAllow sufficient ventilation in greenhousesUse resistant varietiesRemove plant debris and destroy it biological control: Remove the affected parts of the plant as soon as signs of infection appear.

The wingless variety is generally predominant but in summer winged aphids can appear too.

Carotenoids are naturally occurring pigments produced in photosynthesizing plants, algae, bacteria and… aphids? These pigments are responsible for the varying coloration found in organisms on Earth. The most common being the orange carrot that owes its bright color to the carotenoid carotene. For pea aphids, carotenoids display green, a darker red/orange, or a yellowish/white color when environmental conditions aren’t as favorable as carotenoid synthesis is a taxing process.
