Cryptognatha Nodiceps
''Cryptognatha nodiceps'', known generally as the coconut scale predator or sugarcane scale predator, is a species of lady beetle in the family Coccinellidae; it is found in the Caribbean region, North America, and Oceania, having been introduced to various countries in an attempt to provide biological pest control of the coconut scale (''Aspidiotus destructor''). Description The larvae of ''Cryptognatha nodiceps'' are dark yellow and elongated, with long waxy outgrowths, and grow to a length of about . The pupae are a similar colour. The adults are shiny, rounded, dome-shaped beetles, about in length. The head and pronotum are brown and the elytra are blackish. Distribution ''Cryptognatha nodiceps'' is native to Trinidad and Tobago and is present in other parts of the Caribbean region and in Florida. It is also present in Colombia, Guyana, Angola, São Tomé and Príncipe, Pakistan and the Philippines. It has been introduced into a number of island groups including Fiji, Fren ...

Guy Anstruther Knox Marshall
Sir Guy Anstruther Knox Marshall FRS (20 December 1871 in Amritsar, Punjab – 8 April 1959 in London), was an Indian-born British entomologist. He was an expert on African and oriental weevils.Beolens, Bo; Watkins, Michael; Grayson, Michael (2011). ''The Eponym Dictionary of Reptiles''. Baltimore: Johns Hopkins University Press. xiii + 296 pp. . ("Marshall", p. 169). Early life Marshall was the youngest of three children born to Laura Frances Pollock (1846–1912), daughter of Sir Frederick Pollock, 1st Baronet and Chief Baron of the Exchequer, and Colonel Charles Henry Tilson Marshall (1841–1927), a district judge. Both Guy's father and his uncle, Major-General George Frederick Leycester Marshall (1843–1934), were naturalists who had produced books on the birds and butterflies of India, Burma, and Ceylon. Marshall was sent from India to a school in Margate where he started a butterfly collection. He transferred his attentions to beetles when he enrolled at Charterhouse. Whe ...

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, coloni ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Beetles Described In 1912
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] |

Biological Pest Control Beetles
Biology is the scientific study of life. It is a natural science with a broad scope but has several unifying themes that tie it together as a single, coherent field. For instance, all organisms are made up of cells that process hereditary information encoded in genes, which can be transmitted to future generations. Another major theme is evolution, which explains the unity and diversity of life. Energy processing is also important to life as it allows organisms to move, grow, and reproduce. Finally, all organisms are able to regulate their own internal environments. Biologists are able to study life at multiple levels of organization, from the molecular biology of a cell to the anatomy and physiology of plants and animals, and evolution of populations.Based on definition from: Hence, there are multiple subdisciplines within biology, each defined by the nature of their research questions and the tools that they use. Like other scientists, biologists use the scientific metho ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mealybug
Mealybugs are insects in the family (biology), family Pseudococcidae, unarmored scale insects found in moist, warm habitats. Many species are considered pest (animal), pests as they feed on plant juices of greenhouse plants, house plants and subtropical trees and also act as a vector (epidemiology), vector for several plant diseases. Some ants live in symbiotic Ant#Relationships with other organisms, relationships with them, protecting them from predators and feeding off the Honeydew (secretion), honeydew which they excrete. Description Mealybugs are Sexual dimorphism, sexually dimorphic: females appear as nymphs, exhibiting reduced morphology, and lack wings, although unlike many female scale insects, they often retain legs and can move. Males are smaller, gnat-like and have wings. Since mealybugs (as well as all other Hemiptera) are hemimetabolous insects, they do not undergo complete metamorphosis in the true sense of the word. However, male mealybugs do exhibit a radical cha ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Psyllidae
Psyllidae, the jumping plant lice or psyllids, are a family of small plant-feeding insects that tend to be very host-specific, i.e. each plant-louse species only feeds on one plant species (monophagous) or feeds on a few closely related plants (oligophagous). Together with aphids, phylloxerans, scale insects and whiteflies, they form the group called Sternorrhyncha, which is considered to be the most "primitive" group within the true bugs (Hemiptera). They have traditionally been considered a single family, Psyllidae, but recent classifications divide the group into a total of seven families; the present restricted definition still includes more than 70 genera in the Psyllidae. Psyllid fossils have been found from the Early Permian before the flowering plants evolved. The explosive diversification of the flowering plants in the Cretaceous was paralleled by a massive diversification of associated insects, and many of the morphological and metabolic characters that the flowering p ...

Aleurodicus Cocois
''Aleurodicus cocois'', commonly known as the coconut whitefly, is a species of whitefly in the family Aleyrodidae; it feeds on coconut and other palm trees in South America and the Caribbean region. Taxonomy This species was first described in 1846 by the English entomologist John Curtis. He named it ''Aleyrodes cocois'', but it was later transferred to the new genus ''Aleurodicus'' by the English entomologist John William Douglas. He had erected the genus to accommodate ''Aleurodicus anonae'', so when it was determined that ''A. anonae'' was a junior synonym of ''A. cocois'', the latter became the type species of the genus. In other parts of the world, there are certain other species of whitefly that attack coconut palms, which are known locally as "coconut whitefly"; these include '' Aleurodicus destructor'' and '' Aleurodicus dispersus'' in tropical southern Asia and Australasia, and '' Aleurodicus pulvinatus'' and ''A. dispersus'' in the Neotropics.

Coccinellidae
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". The na ...

Coccidae
The Coccidae are a family of scale insects belonging to the superfamily Coccoidea. They are commonly known as soft scales, wax scales or tortoise scales. The females are flat with elongated oval bodies and a smooth integument which may be covered with wax. In some genera they possess legs but in others, they do not, and the antennae may be shortened or missing. The males may be winged or wingless.
