Brevicoryne
''Brevicoryne'' is a genus of aphid insect that contains many species which are agricultural pests. Hosts This genus parasite, parasitizes a wide range of hosts, with many members of the Brassicaceae (broccoli, cabbage, kale, etc.) included. Adults Adults are distinguished from the nymphs by their darker body. They may (alate) or may not exhibit wings. Parasites Many species of Parasitoid wasp, wasps parasitize the juvenile (nymph); injecting their egg (biology), eggs using their ovipositor creating 'mummies' (so called because of their desiccated appearance).

Brevicoryne Brassicae
''Brevicoryne brassicae'', commonly known as the cabbage aphid or cabbage aphis, is a destructive aphid (plant louse) native to Europe that is now found in many other areas of the world. The aphids feed on many varieties of produce, including cabbage, broccoli (especially), Brussels sprouts, cauliflower and many other members of the genus ''Brassica'', but do not feed on plants outside of the family Brassicaceae. The insects entirely avoid plants other than those of Brassicaceae; even though thousands may be eating broccoli near strawberries, the strawberries will be left untouched.University of Minnesota extension Cabbage aphids, from the '' [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Aphid
Aphids are small sap-sucking insects in the Taxonomic rank, family Aphididae. Common names include greenfly and blackfly, although individuals within a species can vary widely in color. The group includes the fluffy white Eriosomatinae, woolly aphids. A typical life cycle involves flightless females giving Viviparity, live birth to female Nymph (biology), nymphs—who may also be already Pregnancy, pregnant, an adaptation scientists call telescoping generations—without the involvement of males. Developmental biology, Maturing rapidly, females breed profusely so that the number of these insects multiplies quickly. Alate, Winged females may develop later in the season, allowing the insects to colonize new plants. In Temperate climate, 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 ...

Brassicaceae
Brassicaceae () or (the older but equally valid) Cruciferae () is a medium-sized and economically important Family (biology), family of flowering plants commonly known as the mustards, the crucifers, or the cabbage family. Most are herbaceous plants, while some are shrubs. The leaves are simple (although are sometimes deeply incised), lack stipules, and appear alternately on stems or in Rosette (botany), rosettes. The inflorescences are terminal and lack bracts. The flowers have four free sepals, four free alternating petals, two shorter free stamens and four longer free stamens. The fruit has seeds in rows, divided by a thin wall (or septum). The family contains 372 genera and 4,060 accepted species. The largest genera are ''Draba'' (440 species), ''Erysimum'' (261 species), ''Lepidium'' (234 species), ''Cardamine'' (233 species), and ''Alyssum'' (207 species). , it was divided into two subfamilies, Brassicoideae and Aethionemoideae. The family contains the cruciferous vegetable ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
