Eggs hatch in early spring and colonies form on young leaves and shoots. They are black in colour, although they can also appear dark green or purple. The eggs of the black bean aphid overwinter on certain host plants which include the spindle tree Euonymus europaeus, Viburnum andPhiladelphus. They are black in colour, although they can also appear dark green or purple. Colonizing flights to summer hosts (beans, corn, sugar beets, lamb's-quarters, pigweed) and have explosive, multiple generations (wingless, asexual females) Fall Winged asexual females and winged sexual males return to winter hosts and have 1 generation of sexual females to produce eggs Adult aphids are up to 2mm long and elliptical in shape. However, many insects and birds eat aphids. Black bean aphids are usually visible on plants because of their contrasting color. bLeqs$0L . The cowpea aphid (Aphis craccivora) appears to be the major natural vector of these viruses as it is the most abundant aphid species on legume crops in the afflicted areas and was among the most efficient vectors under experimental conditions. Only the subspecies euonymi is considered abundant enough to affect counts of eggs significantly (Way et al. The prolific reproductive capabilities of bean aphid has made it a notorious enemy of farmers and gardeners. Black bean aphids are usually visible on plants because of their contrasting colour and the presence of ants. Aphids feed by sucking plant juices, so infested growth is often yellowed and curled. The cowpea aphid has a shiny black body with white appendages and ranges from 1.5 to 2.5 mm long. The overwintering plant host is spindle (Euonymus europaeus). You may not notice black bean aphids (Aphis fabae) until they mass on your dahlia's new stems and leaves, but they've been hanging around for months.The current generation spent the winter and spring as eggs or wingless females on spindle trees (Euonymus spp), snowball bushes (Viburnum spp.) Black Fly Aphid - The Bean Aphid As Black Fly are easy to see, we have the advantage of being able to deal with it - getting rid of it - before it can do too much damage. is by far the most abundant aphid on E. europaeus in England (Way et al.

The female lays about 30 eggs, without mating (this means that she does not need a male to have eggs). In beans plants lose vigour and flowers and pods are affected resulting in poor pod development and loss of yield. Black bean aphid is, however, a relatively poor vector of plant viruses, compared with other economically-important aphids such as Green peach aphid. During the spring and summer months, most aphid species comprise only of females that produce live young. Ants protect aphid eggs during the winter, and carry the newly hatched aphids to new host plants, where the aphids feed on the leaves and the ants get a supply of honeydew. Aphids also transmit virus diseases such as broad bean wilt. The two cornicles (or siphunculi) are short and usually darker than the body. Adult wingless aphids are 1.5-3.1 mm long. These is a sap-sucking insects can form dense colonies on the soft young growth of many plants.

Prevalence of natural fungal mortality of black bean aphid, Aphis fabae Scopoli on primary host and two secondary hosts. Aphids attack fruit trees, roses, camellias, chrysanthemums other ornamentals and a wide range of vegetables. These give birth, parthenogenetically (i.e without the need to mate) to daughters that are also wingless and asexual, and which in turn give birth to wingless duaghters. Unless aphid-infested plants are “failing” [3], or honeydew is causing a problem, control of aphids is not necessary. The black molds that grow on honeydew are harmless to plants [3]. In the summer, they move on to Broad Beans, Nasturtium and Dahlias. In spring wingless, asexual females hatch from the eggs.

The distribution of life cycle variation in aphids is generally determined by ecological forces, mainly climate, because only sexually produced diapausing eggs can survive harsh winters or periods of absence of suitable host plants. In addition, adult wasps feed on aphid honeydew secretions, which is similar to host feeding in other parasitoid–host systems. They have complex life cycles involving different host plants.
