* More aphid species in the keys * Approximately new references It features those aspects of the biology of aphids most relevant to their taxonomy and identification, followed by a crop-oriented illustrated identification guide. It also includes a comprehensive, systematic account of the genera and species of aphids inhabiting crop plants. Most people know of aphids as garden pests, infesting the soft green tissues of plants in vast numbers and killing them by sucking out the sap. Indeed, among the or so known species of aphids about are pests, and in temperate regions several are economically important agricultural pests that damage crops directly during feeding or act as v.

Foxglove aphid, Aulacorthum solani, is usually light green with slightly darker green spots at the base of the cornicles (long tubes that look like dual “exhaust pipes” at the rear), but it has several color forms, ranging from green to orange to adults are browner in color than the wingless forms, and have various black markings.
Foxglove aphids also have black banding on. Biology of the foxglove aphid in the Northeastern United States / By H. (Herbert E.) Wave, Geddes W. Simpson and Wayland Arthur Shands Abstract. The permanent foxglove aphid does not host alternate.
Aphis armata only feeds on foxglove (Digitalis purpurea). Sexual forms occur in autumn. The species has been found in several countries in Europe, but is probably under-recorded because of difficulties in identification.
Plants att acked by foxglove aphid Foxglove aphids can infest an impressive variety of ornamental and vegetable plants (both herbaceous and woody), and have been reported on over 95 different plant species. Foxglove aphids can infest just about every ornamental that’s attacked by green peach or melon aphid, plus a few more.
Greenhouse floriculture growers in the Northeastern U.S., Canada, and the UK currently have to contend with both green peach aphid (Myzus persicae Sulzer) and foxglove aphid (Aulacorthum solani.
These range from grain crops and brassicas to potato, cotton, vegetable and fruit crops. This book provides a definitive reference volume on the biology of aphids, their pest status, and how to control them. It includes approximately 30 specially commissioned chapters from world experts, principally from Europe and North America.
The adults, mummies, and final-instar larvae of the eight hymenopterous parasites of the pea aphid, Acyrthosiphon pisum (Harris), in Eastern Canada are described and illustrated. The history, synonymy, and biology of each species, and the problems of species differentiation in two of the genera, Aphidius and Praon, are discussed.
Keys are given. Aphis armata (Foxglove aphid) The adult apterae of Aphis armata are black, rarely with any white wax spots (se first picture below).
The middle abdominal tergites in apterae are usually without dark sclerotic bands, but they may have a few scattered sclerites, and the largest apterae may have segmental bands. Explore the latest full-text research PDFs, articles, conference papers, preprints and more on CRUSTACEAN BIOLOGY.

Foxglove aphid is found almost world-wide, but is probably of European origin. Host Plants. Although having a very wide host range, foxglove aphid is a pest principally of potato. The foxglove aphid, Aulacorthum solani Kaltenbach (Hemiptera: Aphididae), originates from Europe and has become a cosmopolitan pest (Blackman and Eastop ).It attacks many commodities such as soybeans in Korea and Japan (Takada et al.
), lettuce in South America (De Conti et al. ), and greenhouse peppers in Spain (Sanchez et al. ).In northeastern America, the foxglove aphid.
The foxglove aphid, Aulacorthum solani (Kaltenbach), recently was documented using the invasive species pale and black swallow-wort (Vincetoxicum rossicum (Kleopow) Barbar. and V. nigrum (L.) Moench, respectively) as host plants.
Because these are new host plant records for this polyphagous species, we investigated foxglove aphid development and reproduction on pale and black swallow. Fully revised and updated, this new edition of Aphids on the Worlds Crops is the only publication to provide non-specialist workers wherever they are in the world, with an identification guide and an information source on one of the main groups of agriculturally important insects.
It incorporates: * The latest information on the biology and distribution of both major and minor aphid pest. Foxglove aphid, Aulacorthum solani (Kaltenbach) (Hemiptera: Aphididae), is a cosmopolitan, polyphagous species (Blackman and Eastop).It has long been known as a minor pest of potatoes (Solanum tuberosum L.) in the northeastern United States (PatchWave et al.
), and in more recent years has become an increasing pest in North America on lettuce. [One of the first scientific investigations of fall color from a systematic viewpoint.

Foxglove aphid is a pest of lettuce in California's Central Coast, although it may also occur on other crops.
Winged aphids are nearly indistinguishable in the field from another pest of lettuce, the lettuce aphid. These two aphids, however, can be distinguished from green peach aphid, which has prominent, converging antennal tubercles.
But unlike other aphids, foxglove aphid also has a toxic saliva, which is injected into the plant as it feeds. The toxin can lead to curled and twisted leaves (Figure 2), spots of dead leaf tissue, and can even cause early e of this, foxglove aphid may cause irreversible cosmetic damage to ornamental plants at much lower numbers than that seen with other types of aphids.
feed and the Foxglove aphids’ saliva is highly toxic to many plants, causing deformation and discoloration. In addition to its toxic saliva, the Foxglove aphid can transmit about 40 plant viruses. However, viral transmission is weak with this species.
The Foxglove aphid is a notable pest on lettuces, peppers, and potatoes. The soybean aphid, Aphis glycines Matsumura, has become the single most important arthropod pest of soybeans in North America.
Native to Asia, this invasive species was first discovered in North America in July and has rapidly spread throughout the northcentral United States, much of southeastern Canada, and the northeastern United States. The aphids are probably best known as "greenfly" on roses or "blackfly" on broad beans.
They belong to a group of insects known as "bugs" or Hemiptera, the mouth parts of which are modified to form piercing and sucking tubes, the insects obtaining their food by sucking plant juices or the blood of other animals.The foxglove aphid on potato and other plants.— The biology, behavior, and morphology ofPraon palitans Muesebeck, an internal parasite of the spotted alfalfa aphid,Therioaphis maculata (Buckton) Biology of the foxglove aphid in the Northeastern United States.—.Foxglove aphid: Somewhat less common.
