Acanthaspis Quinquespinosa
''Acanthaspis quinquespinosa'' is a species of assassin bug found in India, Sri Lanka, Myanmar, Nepal and Tibet. It is a predator, and both nymphs and adults feed on termites, beetles, caterpillars and other insect prey. Description The adult ''Acanthaspis quinquespinosa'' is a warningly-coloured, winged assassin bug that varies in appearance depending on the habitat in which it occurs. The overall colour is dark brown to black, with a reddish-brown abdomen and legs, and yellowish spots on the pronotum and fore-wings. There are two spines or prominent tubercles near the centre of the posterior lobe of the pronotum, and two long spines at the posterior margin; the scutellum bears a single spine at its apex. The insects are about long, with males being somewhat smaller than females. It is a common species; the colouring is similar to that of '' Acanthaspis angularis'' and ''Acanthaspis flavipes'', but they can be distinguished by differences in the male genitalia.

Johan Christian Fabricius
Johan Christian Fabricius (7 January 1745 – 3 March 1808) was a Danish 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 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 at 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, 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 remained dependent on subsidies from his father, who worked as a consultant at Frederiks Hospita ...

Dysdercus Koenigii
''Dysdercus koenigii'' is a species of true bug in the family Pyrrhocoridae, commonly known as the red cotton stainer. It is a serious pest of cotton crops, the adults and older nymphs feeding on the emerging bolls and the cotton seeds as they mature, transmitting cotton staining fungi as they do so. Description The nymphs moult five times as they grow. The first and second instar nymphs are orange/red, and the third instar has emerging wingpads and is orange at first, deepening in colour by the second day. The fourth instar is crimson and cylindrical with larger, darker wingpads and the fifth instar is similar, with prominent dark wingpads, black antennae and legs. The adult insect is also crimson, with a pair of black spots on the forewings. The membranous hind wings are concealed under the forewings when the insect is at rest. Males are about in length and females are a little larger. Distribution ''Dysdercus koenigii'' is commonly found in India, Pakistan and southeastern ...

Hemiptera Of Asia
Hemiptera (; ) is an order (biology), order of insects, commonly called true bugs, comprising over 80,000 species within groups such as the cicadas, aphids, planthoppers, leafhoppers, Reduviidae, assassin bugs, Cimex, bed bugs, and shield bugs. They range in size from to around , and share a common arrangement of piercing-sucking Insect mouthparts, mouthparts. The name "true bugs" is often limited to the suborder Heteroptera.

Coptotermes Heimi
''Coptotermes heimi'' is a species of termite in the family Rhinotermitidae. It is found in India, Pakistan and Bangladesh and lives wholly underground. Distribution and habitat ''Coptotermes heimi'' occurs in Pakistan, the Indian states of Rajasthan, Uttar Pradesh and Punjab, and in Bangladesh. It is a serious pest in both agricultural and urban areas, but being a subterranean termite, its presence is not always apparent. Besides attacking logs and structuralt timbers, it can attack living trees, hollowing out the centre. Ecology ''Coptotermes heimi'' make subterranean tunnels in order to forage for suitable food sources. If the surface soil is either too hot or too cold, the termites move deeper into the soil, but when conditions are equable, the foraging tunnels are about beneath the surface. The direction in which the termites dig the tunnels is influenced by the humidity of the soil, and the presence of rotten wood also acts as an attractant. Many termites work together to ...

Rice Moth
The rice moth (''Corcyra cephalonica'') is a moth of the family Pyralidae. This small moth can become a significant pest. Its caterpillars feed on dry plantstuffs such as seeds, including cereals (e.g. rice). Other recordedGrabe (1942) foods are flour and dried fruits. Synonyms Other scientific names, now invalid, for the rice moth are:See references in Savela (2009) * ''Anerastia lineata'' Legrand, 1965 * ''Corcyra translineella'' Hampson, 1901 * ''Melissoblaptes cephalonica'' Stainton, 1866 * ''Melissoblaptes oeconomellus'' Mann, 1872 * ''Tineopsis theobromae'' Dyar, 1913 When describing his ''T. theobromae'' in 1913, Dyar established the genus ''Tineopsis''. He overlooked, however, that this had already been proposed by Cajetan Freiherr von Felder for a (presumed) arctiid moth in 1861. Nonwithstanding that Felder's species is somewhat dubious and has not been identified in recent lists, Dyar's ''Tineopsis'' is a junior homonym and thus invalid in any case. The species of ...

Pink Bollworm
The pink bollworm (''Pectinophora gossypiella''; es, lagarta rosada) is an insect known for being a pest in cotton farming. The adult is a small, thin, gray moth with fringed wings. The larva is a dull white caterpillar with eight pairs of legs with conspicuous pink banding along its dorsum. The larva reaches one half inch in length. The female moth lays eggs in a cotton boll, and when the larvae emerge from the eggs, they inflict damage through feeding. They chew through the cotton lint to feed on the seeds. Since cotton is used for both fiber and seed oil, the damage is twofold. Their disruption of the protective tissue around the boll is a portal of entry for other insects and fungi. The pink bollworm is native to Asia, but has become an invasive species in most of the world's cotton-growing regions. It reached the cotton belt in the southern United States by the 1920s. It was a major pest in the cotton fields of the southern California deserts. The USDA announced in 2018 tha ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Spodoptera Litura
''Spodoptera litura'', otherwise known as the tobacco cutworm or cotton leafworm, is a nocturnal moth in the family Noctuidae. ''S. litura'' is a serious polyphagous pest in Asia, Oceania, and the Indian subcontinent that was first described by Johan Christian Fabricius in 1775. Its common names reference two of the most frequent host plants of the moth. In total, 87 species of host plants that are infested by ''S. litura'' are of economic importance. The species parasitize the plants through the larvae vigorous eating patterns, oftentimes leaving the leaves completely destroyed. The moth's effects are quite disastrous, destroying economically important agricultural crops and decreasing yield in some plants completely. Their potential impact on the many different cultivated crops, and subsequently the local agricultural economy, has led to serious efforts to control the pests. ''S. litura'' is often confused with its close relative, ''Spodoptera littoralis''. These two species ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Helicoverpa Armigera
''Helicoverpa armigera'' is a species of Lepidoptera in the family Noctuidae. It is known as the cotton bollworm, corn earworm, Old World (African) bollworm, or scarce bordered straw (the lattermost in the UK, where it is a migrant). The larvae feed on a wide range of plants, including many important cultivated crops. It is a major pest in cotton and one of the most polyphagous and cosmopolitan pest species. It should not be confused with the similarly named larva of the related species ''Helicoverpa zea''. Distribution This species comprises two sub-species: ''Helicoverpa armigera armigera'' is native and widespread in central and southern Europe, temperate Asia and Africa; ''Helicoverpa armigera conferta'' is native to Australia, and Oceania. The former sub-species has also recently been confirmed to have successfully invaded Brazil and has since spread across much of South America and reached the Caribbean. It is a migrant species, able to reach Scandinavia and other northern ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Oxycarenus Laetus
''Oxycarenus laetus'', commonly known as the dusky cotton bug, is a species of plant bug belonging to the family Lygaeidae. It is sometimes known as the Egyptian cotton stainer, and is found in southern Asia where it is a pest of cotton, okra and other crops. Distribution ''Oxycarenus laetus'' is found in Iraq, Pakistan, India, Myanmar, Malaysia, Cambodia, Vietnam and Laos. In India and Pakistan it displaces ''Oxycarenus hyalinipennis'' on cotton; this species, commonly known as the cotton seed bug, occupies a similar niche in other cotton-growing regions of the world, with the exception of North America.Samy, O. 1969.

Odontotermes Wallonensis
''Odontotermes'', commonly known as the fungus-growing termites, is a termite genus belonging to family Termitidae, which is native to the Old World. They are most destructive in wooden homes, and are agricultural pests in the tropics and subtropics of Africa and Asia. It is the most diverse termite genus in Africa, with 78 species recorded (as of 2002). Nests Their underground nests form a slight mound above ground, which may be covered in grass. In large colonies, the mounds may be up to in diameter, and may be covered by shrubs and trees. Some species construct open chimneys or vent holes that descend into the mound. The fungal garden is enveloped by a thick layer of clay. Castes The queen is imprisoned in a clay cell in the midst of the fungal garden at the center of the hive. The African species have a single soldier cast, unlike the related genus ''Macrotermes''. Food Their only food is the fungus grown in the fungal garden at the center of the nest. The fungus is cultiv ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Reduviidae
The Reduviidae are a large cosmopolitan family of the order Hemiptera (true bugs). Among the Hemiptera and together with the Nabidae almost all species are terrestrial ambush predators: most other predatory Hemiptera are aquatic. The main examples of nonpredatory Reduviidae are some blood-sucking ectoparasites in the subfamily Triatominae. Though spectacular exceptions are known, most members of the family are fairly easily recognizable; they have a relatively narrow neck, sturdy build, and a formidable curved proboscis (sometimes called a rostrum). Large specimens should be handled with caution, if at all, because they sometimes defend themselves with a very painful stab from the proboscis. Taxonomy The Reduviidae are members of the suborder Heteroptera of the order Hemiptera. The family members are almost all predatory, except for a few blood-sucking species, some of which are important as disease vectors. About 7000 species have been described, in more than 20 recognized subfa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hycleus
''Hycleus'' is a genus of blister beetle belonging to the Meloidae family found in Africa and Asia. The genus contains over 400 species, which historically have been confused with the genus ''Mylabris''. Ecology Adults feed mainly on flowers from a wide range of plant families. The first larval instar is an active triungulin form that is a predator of soft insects such as aphids. While the young are often beneficial to crops by suppressing other plant feeders, the adults can be a problem when present in large numbers. Flower feeding leads to lower yield and this can be a problem in some leguminous crops. They are however easily controlled by manual collection. In northern Nigeria, heavy infestations of '' Hycleus terminatus'', '' Hycleus fimbriatus'', '' Hycleus hermanniae'', and '' Hycleus chevrolati'' have affected early plantings of pearl millet crops.
