Micraspis Discolor
''Micraspis discolor'' is a species of ladybird. It was described by Johan Christian Fabricius in 1798. It is widespread throughout Asia, North America and parts of Oceania. Distribution It is found in Bangladesh, China, India, Malaysia, Sri Lanka, Taiwan, Vietnam, United States, Hawaii and Tonga. Description Body length is 5 to 6 mm. Adult has a reddish orange body which is oval in shape. There are black stripes on elytra. Biology It is one of the most common lady beetle found in rice ecosystems particularly during flowering and feeds on pollen. The species can be used as a bio-control agent for brown planthopper. It is found as both entomophagous and phytophagous species of beetle. Both adult beetles and nymphs are voracious predators on several pests such as, ''Aphis craccivora'', ''Aphis gossypii'', ''Aphis spiraecola'', ''Leptocorisa acuta'', ''Myzus persicae'', ''Nephotettix cincticeps'', ''Opisina arenosella'', ''Pentalonia nigronervosa'' and ''Sogatella furcifera'' ...

Johan Christian Fabricius
Johan Christian Fabricius (7 January 1745 – 3 March 1808) was a Danish zoology, zoologist, specialising in "Insecta", which at that time included all arthropods: insects, arachnids, crustaceans and others. He was a student of Carl Linnaeus, and is considered one of the most important entomologists of the 18th century, having named nearly 10,000 species of animals, and established the basis for the modern insect Biological classification, classification. Biography Johan Christian Fabricius was born on 7 January 1745 at Tønder in the Duchy of Schleswig, where his father was a doctor. He studied at the gymnasium (school), gymnasium at Altona, Hamburg, Altona and entered the University of Copenhagen in 1762. Later the same year he travelled together with his friend and relative Johan Zoëga to Uppsala University, Uppsala, where he studied under Carl Linnaeus for two years. On his return, he started work on his , which was finally published in 1775. Throughout this time, he remaine ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ladybird
Coccinellidae () is a widespread family of small beetles ranging in size from . They are commonly known as ladybugs in North America and ladybirds in Great Britain. Some entomologists prefer the names ladybird beetles or lady beetles as they are not true bugs. Many of the species have conspicuous aposematic colours and patterns, such as red with black spots, that warn potential predators that they are distasteful. The majority of the more than 6,000 described species are generally considered beneficial insects, because many prey on herbivorous hemipterans such as aphids or scale insects, which are agricultural pests. Many coccinellids lay their eggs directly in aphid and scale insect colonies, ensuring their larvae have an immediate food source. However, some species such as the herbivorous Mexican bean beetle are agricultural pests. Etymology The name ''coccinellids'', created by Pierre André Latreille, is derived from the Latin word ''coccineus'' meaning "scarlet" ...

Integrated Taxonomic Information System
The Integrated Taxonomic Information System (ITIS) is an American partnership of federal agencies designed to provide consistent and reliable information on the taxonomy of biological species. ITIS was originally formed in 1996 as an interagency group within the US federal government, involving several US federal agencies, and has now become an international body, with Canadian and Mexican government agencies participating. The database draws from a large community of taxonomic experts. Primary content staff are housed at the Smithsonian National Museum of Natural History and IT services are provided by a US Geological Survey facility in Denver. The primary focus of ITIS is North American species, but many biological groups exist worldwide and ITIS collaborates with other agencies to increase its global coverage. Reference database ITIS provides an automated reference database of scientific and common names for species. As of May 2016, it contains over 839,000 scientific nam ...

Brown Planthopper
The brown planthopper (BPH), ''Nilaparvata lugens'' (Stål) (Hemiptera: Delphacidae) is a planthopper species that feeds on rice plants (''Oryza sativa'' L.). These insects are among the most important pests of rice, which is the major staple crop for about half the world's population. They damage rice directly through feeding and also by transmitting two viruses, rice ragged stunt virus and rice grassy stunt virus. Up to 60% yield loss is common in susceptible rice cultivars attacked by the insect. The BPH is distributed throughout Australia, Bangladesh, Bhutan, Burma (Myanmar), Cambodia, China, Fiji, India, Indonesia, Japan, North and South Korea, Laos, Malaysia, India, Nepal, Pakistan, Papua New Guinea, Philippines, Sri Lanka, Taiwan, Thailand, and Vietnam. Their alternative host plant other than rice is '' Leersia hexandra''. Biology The brown planthopper is dimorphic, with fully winged 'macropterous' and truncate-winged 'brachypterous' forms. The macropterous forms are pote ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Aphis Craccivora
''Aphis craccivora'', variously known as the cowpea aphid, groundnut aphid or black legume aphid, is a true bug in the family ''Aphididae''. Originally of probable Palearctic origin, it is now an invasive species of cosmopolitan distribution. Description ''Aphis craccivora'' is a small species of aphid. The female has a glossy black or dark brown body with a prominent cauda (tail-like protrusion), and legs in some shade of brown or yellow. The antennae have six segments and these and the limb segments, cauda and cornicles are pale proximally (close to the body) and dark distally (further from the body). The adults do not have wax on their dorsal surface but the nymphs are lightly dusted with wax. Winged females are up to long and have cross-barring on the abdomen. Wingless females are a little smaller. Distribution ''Aphis craccivora'' is believed to be Palearctic in origin but has expanded its range so that now it is near cosmopolitan. In recent years its range has extended fu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Aphis Gossypii
''Aphis gossypii'' is a tiny insect, an aphid ("greenfly") in the superfamily Aphidoidea in the order Hemiptera. It is a true bug and sucks sap from plants. It is a widely distributed pest of a variety of agricultural crops in the families Cucurbitaceae, Rutaceae and Malvaceae. Common names include cotton aphid, melon aphid and melon and cotton aphid. Distribution It is not known where this species originated, but it is now found in tropical and temperate regions throughout the world except extreme northern areas. It is common in North and South America, Central Asia, Africa, Australia, Brazil, East Indies, Mexico and Hawaii and in most of Europe. It is cosmopolitan in habitat. It thrives outdoors in southern Europe but survives only under glass in northern Europe. In the former Soviet Union it is found up to 54°N. Morphology The wingless female cotton aphid has an ovoid body about two millimetres long in varying shades of green. The legs are yellow, as are the antennae whi ...

Aphis Spiraecola
''Aphis spiraecola'' is a species of aphid described in 1914 by Edith Marion Patch. Its common names include green citrus aphid, Spirea aphid, and apple aphid. It is distributed worldwide, and is most abundant in the United States. It has a diploid chromosome number of 2n=8. Discovery This species was first discovered by Edith Marion Patch in 1914. Patch discovered that '' A. pomi'' would feed and develop on ''Spiraea'' and ''A. spiraecola'' would feed and develop on ''Malus'' which confirmed that aphids were a highly variable species. Patch’s colonies on apple were decimated by a fungus so all transfer attempts to secondary hosts, which would have demonstrated the limited host range of ''A. pomi'', were made using ''A. spiraecola'' from ''Spiraea'' instead. Later she suggested using the names ''A. pomi'' and ''A. spiraecola'' on the basis of the plants on which they were found thus leading to the names each species is known by today. Another species, ''A. citricola'' was de ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Leptocorisa Acuta
''Leptocorisa acuta'',Thunberg CP (1783) ''Dissertatio entomologica novas insectorum species, sistens, cujus partem secundum, Edman, Upsaliae'' 2: 29-52. the paddy earhead bug, is a species of bug recorded from northern Australia, Malesia and Taiwan. Its basionym is ''Cimex acutus'' and it is now placed in the family Alydidae. One of several rice bug species, it may be confused with '' Leptocorisa oratoria''. Pest status Rice bugs can be a significant pest of the rice plant, as they feed-on developing ( milk stage) grains: reducing crop quality and sometimes yield. Because attacks occur near to harvest, if farmers spray insecticides in an attempt to control outbreaks, they risk leaving harmful pesticide residues on the crop. It is also a pest of sorghum, pearl millet, and finger millet ''Eleusine coracana'', or finger millet, also known as ragi in India, kodo in Nepal, is an annual herbaceous plant widely grown as a cereal crop in the arid and semiarid areas in Afric ...

Myzus Persicae
''Myzus persicae'', known as the green peach aphid, greenfly, or the peach-potato aphid, is a small green aphid belonging to the order Hemiptera. It is the most significant aphid pest of peach trees, causing decreased growth, shrivelling of the leaves and the death of various tissues. It also acts as a vector for the transport of plant viruses such as cucumber mosaic virus (CMV), potato virus Y (PVY) and tobacco etch virus (TEV). Potato virus Y and potato leafroll virus can be passed to members of the nightshade/potato family (Solanaceae), and various mosaic viruses to many other food crops. Originally described by Swiss entomologist Johann Heinrich Sulzer in 1776, its specific name is derived from the Latin genitive ''persicae,'' "of the peach". The syntype specimen of this species is located in the Illinois Natural History Survey Insect Collection. Life cycle Life cycle of the green peach aphid varies depending on temperature. A fully completed generation takes approxima ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Opisina Arenosella
The Coconut black headed caterpillar (''Opisina arenosella''), is a species of moth found in multiple regions throughout East Asian countries including Bangladesh, India, Sri Lanka, Myanmar, as well as Indonesia. It is considered a pest to these countries, as they infest coconut palm trees, causing considerable damage to the trees, and reducing the plant's yield significantly. This is a great burden to all countries who experience infestations, as coconut is one of the main crops driving the economy. The species exists on coconut palms in all forms, from larval to moth, and utilizes the tree fronds as a main source of nutrition. Various methods of control have been explored, yet the primary control method is the administration of pesticides directly to the root of the coconut palms. Identification The coconut black-headed caterpillar is identifiable in the larval form as a caterpillar with greenish brown with dark brown head and prothorax, and a reddish mesothorax. There are o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
