Aulacophora Nigripennis
''Aulacophora nigripennis'' is a species of leaf beetle in the genus Aulacophora ''Aulacophora'' is a genus of beetles in the family Chrysomelidae, commonly known as pumpkin beetles; some species are pests of agricultural crops. The genus was named in 1836 by the French entomologist Louis Alexandre Auguste Chevrolat, in Deje .... Description The beetle is relatively small with a hard, black exoskeleton containing faint yellowish dots around the sides. The head is a deep, bright orange, while ''A. nigripennis'' has a large orange compartmentalized thorax. Feeding A. nigripennis is a pest that feeds off of the 28 species in the '' Dianthus'' and '' Tricosantes'' genera of plants by creating a circular "trench" using its mandibles. After circularly cutting through the leaf, the trench overflows with sticky phloem sap that, through cohesion, sticks to form a semicircle around the beetle. The beetle then sucks the sap using its mouth. Pest control Researchers at the Journal ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Victor Motschulsky
Victor Ivanovich Motschulsky (sometimes Victor von Motschulsky, russian: link=no, Виктор Иванович Мочульский, 11 April 1810, in St. Petersburg – 5 June 1871, in Simferopol) was a Russian entomologist mainly interested in beetles. Motschulsky was an Imperial Army colonel who undertook extended trips abroad. He studied and described many new beetles from Siberia, Alaska, the United States, Europe, and Asia. While he tended to ignore previous work and his own work on classification was of poor quality, Motschulsky made a massive contribution to entomology, exploring hitherto unworked regions, often in very difficult terrain. He described many new genera and species, a high proportion of which remain valid. Travels Motschulsky's travels included: *1836 - France, Switzerland and the Alps, northern Italy and Austria *1839–1840 - Russian Caucasus, Astrakhan, Kazan and Siberia *1847 - Khirgizia *1850–1851 - Germany, Austria, Egypt, India, France, England, ...

Leaf Beetle
The insects of the beetle family Chrysomelidae are commonly known as leaf beetles, and include over 37,000 (and probably at least 50,000) species in more than 2,500 genera, making up one of the largest and most commonly encountered of all beetle families. Numerous subfamilies are recognized, but the precise taxonomy and systematics are likely to change with ongoing research. Leaf beetles are partially recognizable by their tarsal formula, which appears to be 4-4-4, but is actually 5-5-5 as the fourth tarsal segment is very small and hidden by the third. As with many taxa, no single character defines the Chrysomelidae; instead, the family is delineated by a set of characters. Some lineages are only distinguished with difficulty from longhorn beetles (family Cerambycidae), namely by the antennae not arising from frontal tubercles. Adult and larval leaf beetles feed on all sorts of plant tissue, and all species are fully herbivorous. Many are serious pests of cultivated plants, f ...

Aulacophora
''Aulacophora'' is a genus of beetles in the family Chrysomelidae, commonly known as pumpkin beetles; some species are pests of agricultural crops. The genus was named in 1836 by the French entomologist Louis Alexandre Auguste Chevrolat, in Dejean's ''Catalogue des Coléoptères''. The name, from Ancient Greek, signifies "furrow-bearer"' from ''aulax'', "furrow". Description Beetles in this genus are oval insects up to about long and can be recognised by their presence on the host plant. Distribution Pumpkin beetles are found in Africa, Asia and Australasia. Some of the more important pest species are '' A. foveicollis'' from Africa, Europe and Asia, '' A. similis'' from southern and southeastern Asia, '' A. coffeae'' from Malaysia, '' A. flavomarginata'' from Malaysia and Indonesia, '' A. femoralis'' from Myanmar and Vietnam, '' A. lewisii'' from Malaysia and Vietnam, and '' A. frontalis'' from Singapore, Thailand, Vietnam and Laos.

Dianthus
''Dianthus'' () is a genus of about 340 species of flowering plants in the family Caryophyllaceae, native mainly to Europe and Asia, with a few species in north Africa and in southern Africa, and one species (''D. repens'') in arctic North America. Common names include carnation (''D. caryophyllus''), pink (''D. plumarius'' and related species) and sweet william (''D. barbatus''). Description The species are mostly herbaceous perennials, a few are annual or biennial, and some are low subshrubs with woody basal stems. The leaves are opposite, simple, mostly linear and often strongly glaucous grey green to blue green. The flowers have five petals, typically with a frilled or pinked margin, and are (in almost all species) pale to dark pink. One species, ''D. knappii'', has yellow flowers with a purple centre. Some species, particularly the perennial pinks, are noted for their strong spicy fragrance. Species Selected species include: Hybrids include; * 'Devon Xera' – Fir ...

Beetles Described In 1857
Beetles are insects that form the order Coleoptera (), in the superorder Endopterygota. Their front pair of wings are hardened into wing-cases, elytra, distinguishing them from most other insects. The Coleoptera, with about 400,000 described species, is the largest of all orders, constituting almost 40% of described insects and 25% of all known animal life-forms; new species are discovered frequently, with estimates suggesting that there are between 0.9 and 2.1 million total species. Found in almost every habitat except the sea and the polar regions, they interact with their ecosystems in several ways: beetles often feed on plants and fungi, break down animal and plant debris, and eat other invertebrates. Some species are serious agricultural pests, such as the Colorado potato beetle, while others such as Coccinellidae (ladybirds or ladybugs) eat aphids, scale insects, thrips, and other plant-sucking insects that damage crops. Beetles typically have a particularly hard exoske ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
