Propylea Dissecta
''Propylea dissecta'', is a species of lady beetle native to India, Sri Lanka, Bangladesh and Nepal. Description This robust beetle is about 5 to 6 mm in length. Elytra reddish orange in color with black central line. Adults show polymorphism with several intermediate and pale forms. Biology Sexual maturity of male and female ladybirds is about 7 and 9 days respectively. Adult males are more willing to mate with females irrespective of age. Mating duration is longest amongst older adults where 30 day-old males and 20 day-old females can be found. Chemical signals as well as visual and tactile cues initiate male attraction toward females. Mating lasted longest about 275 minutes when it occurred between unmated individuals. It is a voracious predator on several aphids such as ''Aphis gossypii'', ''Aphis craccivora'', ''Lipaphis erysimi'', ''Uroleucon compositae'', ''Brevicoryne brassicae'', ''Rhopalosiphum maidis ''Rhopalosiphum maidis'', common names corn leaf aphid and corn ...

Arthropod
Arthropods (, (gen. ποδός)) are invertebrate animals with an exoskeleton, a Segmentation (biology), segmented body, and paired jointed appendages. Arthropods form the phylum Arthropoda. They are distinguished by their jointed limbs and Arthropod cuticle, cuticle made of chitin, often Mineralization (biology), mineralised with calcium carbonate. The arthropod body plan consists of segments, each with a pair of appendages. Arthropods are bilaterally symmetrical and their body possesses an exoskeleton, external skeleton. In order to keep growing, they must go through stages of moulting, a process by which they shed their exoskeleton to reveal a new one. Some species have wings. They are an extremely diverse group, with up to 10 million species. The haemocoel, an arthropod's internal cavity, through which its haemolymph – analogue of blood – circulates, accommodates its interior Organ (anatomy), organs; it has an open circulatory system. Like their exteriors, the internal or ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Insect
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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Beetle
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 har ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Polyphaga
Polyphaga is the largest and most diverse suborder of beetles. It comprises 144 families in 16 superfamilies, and displays an enormous variety of specialization and adaptation, with over 350,000 described species, or approximately 90% of the beetle species so far discovered. Key characteristics of Polyphaga are that the hind coxa (base of the leg) does not divide the first and second abdominal/ventral plates which are known as sternites. Also, the notopleural suture (found under the pronotal shield) is not present. Etymology The name of ''polyphaga'' is derived from two Greek words: , meaning 'many', and , meaning 'to eat', so the suborder is called the “eaters of many things”. Classification The five main infraorders are: * Bostrichiformia — including furniture beetles and skin beetles * Cucujiformia — includes lady beetles, longhorn beetles, weevils, checkered beetles and leaf beetles * Elateriformia — includes click beetles and fireflies * Scarabaeif ...

Coccinelloidea
Coccinelloidea is a superfamily of beetles in the order Coleoptera, formerly included in the superfamily Cucujoidea. There are more than 10,000 species in Coccinelloidea, including more than 6000 in the lady beetle family Coccinellidae. Morphology Adult Coccinelloidea have a reduced tarsal formula (each tarsus with 4 or 3 segments), hind coxae separated by more than 1/3 their width, the intercoxal process of abdominal ventrite 1 usually broadly rounded or truncate, hindwings with reduced anal veins and lacking a closed radial cell, the adeagus resting on its side when retracted and the phallobase usually reduced. Larval Coccinelloidea have a unisetose pretarsal claw, spiracles that are usually annular, and the sensory appendage of the second antennal segment usually as long as the third segment. Families The family constituency of this lineage has changed considerably over time, from as few as four or five recognized families in 1970 to 15 in 2015. * Akalyptoischiidae Lor ...

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 "scarl ...

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] |
