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 ...

Aspidiotus Destructor
''Aspidiotus destructor'', the coconut scale, is a species of armoured scale insect in the family Diaspididae, found in many tropical and subtropical parts of the world. It is a serious pest of coconut and banana, and attacks a range of other fruiting trees and ornamental plants. Description All but the first instar nymphs live under the protection of a waxy test or scale and remain in one place. First instar nymphs have legs and move about looking for somewhere to settle. Second instar and adult females have rounded, flattish tests up to in diameter. They have no eyes or appendages, and their soft yellow bodies are visible through the translucent test, giving them the appearance of miniature fried eggs. Males have smaller, more elongated tests, and pass through a pseudo-pupal stage before metamorphosing into reddish, gnat-like insects with eyes, antennae, legs and wings, but no mouthparts.

Aleurodicus Dispersus
''Aleurodicus dispersus'', the spiralling whitefly, is a species of small, white sap-sucking insect, a true bug in the order Hemiptera. It originated in Central America and the Caribbean region and has spread to many of the world's tropical and subtropical regions, where it has become a major pest of agricultural crops. Description Adult spiralling whitefly are small, white, moth-like insects some 1/12-1/8 inch (2–3 mm) long. When they emerge from the pupal casing, the wings are transparent, but they soon become dusted with white fragments of wax. Each of the forewings bear a characteristic pair of black spots and the eyes in this species are a dark reddish brown. Distribution ''Aleurodicus dispersus'' is native to Central America and the Caribbean but is not regarded as a pest species in these areas. Since the middle of the 20th century it has spread to many parts of the tropics and subtropics. It was found and intercepted in the 1950s on imports into the United States b ...

Insects Of Sri Lanka
Insects (from Latin ') are pancrustacean hexapod invertebrates of the class Insecta. They are the largest group within the arthropod phylum. Insects have a chitinous exoskeleton, a three-part body (head, thorax and abdomen), three pairs of jointed legs, compound eyes and one pair of antennae. Their blood is not totally contained in vessels; some circulates in an open cavity known as the haemocoel. Insects are the most diverse group of animals; they include more than a million described species and represent more than half of all known living organisms. The total number of extant species is estimated at between six and ten million; In: potentially over 90% of the animal life forms on Earth are insects. Insects may be found in nearly all environments, although only a small number of species reside in the oceans, which are dominated by another arthropod group, crustaceans, which recent research has indicated insects are nested within. Nearly all insects hatch from eggs. Insect ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
