19971

• In Kenya, foliar sprays with neem products such as Neemroc(R) (1-3%) and Neemros(R) water extract (50g/l) controlled the black bean aphid on vegetables (Maundu, 1997). (infonet-biovision.org)

Pests1

• Aphids are among the most destructive insect pests on cultivated plants in temperate regions. (wikipedia.org)

Females1

• Winged females may develop later in the season, allowing the insects to colonize new plants. (wikipedia.org)

Species8

• About 5,000 species of aphid have been described, all included in the family Aphididae. (wikipedia.org)
• In contrast to many taxa, aphid species diversity is much lower in the tropics than in the temperate zones. (wikipedia.org)
• Aphids have also been spread by human transportation of infested plant materials, making some species nearly cosmopolitan in their distribution. (wikipedia.org)
• With their soft bodies, aphids do not fossilize well, and the oldest known fossil is of the species Triassoaphis cubitus from the Triassic. (wikipedia.org)
• In 1967, when Professor Ole Heie wrote his monograph Studies on Fossil Aphids, about sixty species have been described from the Triassic, Jurassic, Cretaceous and mostly the Tertiary periods, with Baltic amber contributing another forty species. (wikipedia.org)
• The total number of species was small, but increased considerably with the appearance of the angiosperms 160 million years ago, as this allowed aphids to specialise, the speciation of aphids going hand-in-hand with the diversification of flowering plants. (wikipedia.org)
• Vicia faba , commonly known as the broad bean , fava bean , or faba bean , is a species of vetch , a flowering plant in the pea and bean family Fabaceae . (wikipedia.org)
• In much of the English-speaking world , the name "broad bean" is used for the large-seeded cultivars grown for human food, while "horse bean" and "field bean" refer to cultivars with smaller, harder seeds that are more like the wild species and used for animal feed , [ citation needed ] though their stronger flavour is preferred in some human food recipes, such as falafel . (wikipedia.org)

Small2

• Aphids are small sap-sucking insects and members of the superfamily Aphidoidea. (wikipedia.org)
• Small aphid populations may be relatively harmless, but heavily infested plants usually have wrinkled leaves, stunted growth and deformed capsules. (infonet-biovision.org)

Control2

• Control of aphids is not easy. (wikipedia.org)
• They are important in natural control of aphids. (infonet-biovision.org)

Worldwide1

• Aphids are distributed worldwide, but are most common in temperate zones. (wikipedia.org)

White2

• The group includes the fluffy white woolly aphids. (wikipedia.org)
• the standard petals are white, the wing petals are white with a black spot (true black, not deep purple or blue as is the case in many "black" colorings) [2] and the keel petals are white. (wikipedia.org)

Common1

• Aphids, and the closely related adelgids and phylloxerans, probably evolved from a common ancestor some 280 million years ago, in the Early Permian period. (wikipedia.org)

High2

• Winged aphids may also rise up in the day as high as 600 m where they are transported by strong winds. (wikipedia.org)
• Unlike most legumes, the broad bean can be grown in soils with high salinity , as well as in clay soil . (wikipedia.org)

Leaves2

• One study alternatively suggests that ancestral aphids may have lived on angiosperm bark and that feeding on leaves may be a derived trait. (wikipedia.org)
• Aphids are a major pest, causing leaves to curl and attacked capsules become unattractive to customers. (infonet-biovision.org)

Early1

• Early capsule infection renders them black and seedless. (infonet-biovision.org)

Female aphids4

• These females start reproducing without mating giving rise to more female aphids. (unl.edu)
• Once on soybeans, multiple generations of wingless female aphids are produced until late summer and early fall. (unl.edu)
• Female aphids may lay eggs or give birth to wingless offspring, known as nymphs. (infonet-biovision.org)
• In the warm parts of the world, as in the tropics, no male aphids are produced and female aphids do not lay eggs but give birth to small nymphs. (infonet-biovision.org)

Fabae2

• The adults are medium to large sized beetles (2 to 5 cm in length), usually black and yellow or black and red in colour. (infonet-biovision.org)

Honeydew4

• So-called dairying ants have a mutualistic relationship with aphids, tending them for their honeydew and protecting them from predators. (wikipedia.org)
• Aphids excrete a sugary, sticky liquid called honeydew that accumulates on leaves and branches. (infonet-biovision.org)
• Sooty moulds (a fungal growth) grow on honeydew deposits turning leaves and branches black. (infonet-biovision.org)
• Aphids excrete honeydew, which leads to growth of sooty mould, and may attract fruit flies. (infonet-biovision.org)

Cotton1

• Before its detection in the continental U.S., Chilli Thrips were considered a serious economic pest in Asia and Australia where it attacked crops such as strawberries, tea, citrus, cotton, soybeans, chilies, castor beans, peanuts, and roses among others. (texasinvasives.org)

Migrate1

• winged aphids are produced when they need to migrate, for example under overcrowded conditions with limited food source or when environmental conditions are unfavourable. (infonet-biovision.org)

Whiteflies1

• Late 20th-century reclassification within the Hemiptera reduced the old taxon "Homoptera" to two suborders: Sternorrhyncha (aphids, whiteflies, scales, psyllids, etc.) and Auchenorrhyncha (cicadas, leafhoppers, treehoppers, planthoppers, etc.) with the suborder Heteroptera containing a large group of insects known as the true bugs. (wikipedia.org)

Diseases2

• Many species of aphids have been implicated as major vectors of plant viral diseases. (infonet-biovision.org)
• Aphids, in particular winged aphids, transmit virus diseases (e.g. cucumber mosaic virus) when moving from plant to plant. (infonet-biovision.org)

Eggs3

• Because Orius insidiosus also feeds on aphids, mites, moth eggs and pollen, its population does not decline strongly even if thrip populations are drastically reduced. (texasinvasives.org)
• Eggs are very tiny, shiny-black, and are found in the crevices of bud, stems, and barks of the plant. (infonet-biovision.org)
• Aphids usually do not lay eggs in warm parts of the world. (infonet-biovision.org)

Populations4

• When daytime high temperatures are between 70‐85oF aphid populations can increase dramatically (populations can double in two to three days). (unl.edu)
• Regular scouting allows you to determine if aphid populations are actively increasing and monitor the natural enemies populations which include Asian lady beetle (Orius insidiosus) (Figure 40), green lacewing (Chyrsoperla spp. (unl.edu)
• The economic threshold , or population infestation level where control measures are recommended, for late vegetative through R5 stage soybeans is 250 aphids per plant with 80% of the plants infested and populations increasing. (unl.edu)
• Small aphid populations may be relatively harmless, but heavily infested plants usually have wrinkled leaves, stunted growth and deformed capsules. (infonet-biovision.org)

Pest2

• Common insect pest of soybeans include soybean aphids, bean leaf beetles, two-spotted spider mite, Japanese beetle, stink bugs and dectes stem borer. (unl.edu)
