Phyllaphis Fagi
''Phyllaphis fagi'', the woolly beech aphid, is a species of aphid in the family Aphididae. Distribution This species can be found in Central and Southern Europe and it has been introduced to the Middle East, Australia, New Zealand and North America. Description ''Phyllaphis fagi'' can reach a length of the oval body of one to three millimeters. Their bodies are light bluish-green. Some specimen show a pronounced dark banding on the abdomen. The antennae are slightly shorter than the body. Winged as well as wingless animals excrete white to bluish-white wax threads, giving them a woolly appearance. Biology This species is monoecious and holocyclic. When a cyclical parthenogenesis occurs, aphids reproduce sexually in the autumn and produce an overwintering egg, deposited on buds and bark crevices of the host plant. In spring the newly hatched nymphs develop in about two to three weeks and at least three molts to wingless, 2–3 mm large Fundatrix. A fundatrix can produce ...

Aphid
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 color. The group includes the fluffy white woolly aphids. A typical life cycle involves flightless females giving live birth to female nymphs—who may also be already pregnant, an adaptation scientists call telescoping generations—without the involvement of males. Maturing rapidly, females breed profusely so that the number of these insects multiplies quickly. Winged females may develop later in the season, allowing the insects to colonize new plants. In temperate regions, a phase of sexual reproduction occurs in the autumn, with the insects often overwintering as eggs. The life cycle of some species involves an alternation between two species of host plants, for example between an annual crop and a woody plant. Some species feed on only one type of plant, while others are generalists, c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Aphididae
The Aphididae are a very large insect family in the aphid superfamily ( Aphidoidea), of the order Hemiptera. These insects suck the sap from plant leaves. Several thousand species are placed in this family, many of which are considered plant/crop pests. They are the family of insects containing most plant virus vectors (around 200 known) with the green peach aphid ('' Myzus persicae'') being one of the most prevalent and indiscriminate carriers. Evolution Aphids originated in the late Cretaceous about (Mya), but the Aphidinae which comprises about half of the 4700 described species and genera of aphids alive today come from their most recent radiation which occurred in the late Tertiary less than 10 Mya.Von Dohlen CD, Moran NA (2000) Molecular data support a rapid radiation of aphids in the Cretaceous and multiple origins of host alternation.

Hemiptera Genera
Hemiptera (; ) is an order of insects, commonly called true bugs, comprising over 80,000 species within groups such as the cicadas, aphids, planthoppers, leafhoppers, assassin bugs, bed bugs, and shield bugs. They range in size from to around , and share a common arrangement of piercing-sucking mouthparts. The name "true bugs" is often limited to the suborder Heteroptera. Entomologists reserve the term ''bug'' for Hemiptera or Heteroptera,Gilbert Waldbauer. ''The Handy Bug Answer Book.'' Visible Ink, 1998p. 1. which does not include other arthropods or insects of other orders such as ants, bees, beetles, or butterflies. In some variations of English, all terrestrial arthropods (including non-insect arachnids, and myriapods) also fall under the colloquial understanding of ''bug''. Many insects with "bug" in their common name, especially in American English, belong to other orders; for example, the lovebug is a fly and the Maybug and ladybug are beetles. The term is also ...
