They are also usually green as in the picture below. Some of these nymphs develop into parthenogenetic females, but over time an increasing number instead develop into either winged males, as in the first image below, or wingless oviparae, as in the second image below. 05), and the seasonal pattern differed in that the aphids remained at low densities after the summer decrease ( Fig. Whilst we make every effort to ensure that identifications are correct, we cannot absolutely warranty their accuracy. Ants and aphids are mutually beneficial to each other, as aphids help provide food for ants. Materials and methods The aphids used in this study were collected from syca-more trees (Acer pseudoplatanus L.) in the grounds of Glasgow University and consisted of the nymphs and Try a hardier species. It looks as though it has the beginnings of a fungal growth from various bits of it. However, a small percentage (up to 17%) of the summer adults are red rather than green (see picture below). 3 . Sycamores have thin, peeling reddish-brown bark and seed balls that drop in spring. The body length is 3.2-4.3 mm. He found that red forms can be induced to develop in the third generation if the aphids are kept at high temperatures. Sycamore lace bugs feed on … Check your trees for aphid infestation by looking at the undersides of leaves. Bob, Influentialpoints:
When aphids feed on trees, their honeydew can drop onto cars, outdoor furniture, driveways, and so on. And it only takes a few predators per plant to significantly cut down on the number of bugs. Spraying the tree with neem oil or insecticidal soap helps control aphids without harming beneficial insects, but the spray has to come into direct contact with the aphid to be effective. Species; Additional images; Click here to support NatureSpot by making a donation - small or large - your gift is very much appreciated. Family Platanaceae (Plane tree family) Plant identification. Aphids attack fruit trees, roses, camellias, chrysanthemums other ornamentals and a wide range of vegetables. Since the disease typically attacks American sycamore trees, try planting a London plane tree or an Oriental plane tree, which are usually resistant to sycamore anthracnose. All adult viviparae are alates. In summer the sycamore aphid's responses to gravity, light direction and intensity and unidentified features of a leaf's surface result in the aphid settling and feeding on the undersurface of leaves. Not all aphids remain on the same tree throught their life. Egg mortality varies from 65-85% with the greatest mortality in late winter (Wade, 2002). Aphids are small sap-sucking insects and members of the superfamily Aphidoidea.Common names include greenfly and blackfly, although individuals within a species can vary widely in colour. How to Get Rid of Aphids on Large Trees (Including Maples) Believe it or not, one effective way to control them is to do nothing at all! Description. Hatching is well synchronised with the average time of bud burst, so the young nymphs are able to exploit highly nutritious young foliage as it emerges from the buds. Nigel Gilligan, 17 March 2014, another Drepanosiphum platanoidis maybe. Thanks for the confirmation - got one right, at least! We have mostly made identifications from high resolution photos of living specimens, along with host plant identity. The forewing has no black spot at the tip nor one at the outer end of the pterostigma; the pterostigma is defined by two longitudinal brown stripes. Among protogynous trees differences in seed set between the two pollination treatments were significant in eight out of ten trees whereas in the other sexual morph it was only in one tree. While aphids feast on all garden plants, there are many species of aphids that are more likely to affect food crops and fruit trees.

Dixon & Logan (1972) showed that the spacing is partly dependent on the density of aphids on the leaf. [Below] are 3 images of what I think may be the Common Sycamore aphid. Found on Tayberry, 12/9/2014. Aphids produce honeydew that supports growth of a black sooty mold fungus. Quite correct, it is Drepanosiphum platanoidis. The leaves are eaten by caterpillars of a number of moths, including the sycamore moth, plumed prominent and maple prominent. This means that red aphids continue to be produced in September but with the black abdominal bars that are also present on the green aphids in spring and autumn.
Although sooty mold is not a bug, ... Often seen on London Plane/Sycamore trees in the city (Platanus acerifolia), it is generally cosmetic and not fatal. Quite correct, it is Drepanosiphum platanoidis. The first image shows the adult braconid Dyscritulus planiceps which emerged from the mummy of a sycamore aphid shown above. Blackman & Eastop list 96 species of aphid as feeding on Acer (Maples and Sycamores) worldwide, and provide formal identification keys.. About sixteen of these are known to occur in Britain. The plant on which overwintering eggs are laid is often a tree or shrub. The eggs of Drepanosiphum platanoidis are laid on rough areas of sycamore bark in the autumn, and hatch in the following March.
