Thripidae
The Thripidae are the most speciose family of thrips, with over 290 genera representing just over two thousand species. They can be distinguished from other thrips by a saw-like ovipositor curving downwards, narrow wings with two veins, and antennae of six to ten antennomeres with stiletto-like forked sense cones on antennal segments III and IV. They are considered to be among the more derived of thrips, having evolved many traits key to specializing as cryptophilous phytovores, living in the narrow spaces at the bases of leaves and within flowers. Several species are economically significant pests, some of them invasive. Almost all of them are typical thrips which belong in the largest subfamily, the Thripinae. Systematics Many of the divisions within the Thripidae are not based on common ancestry, but are instead based on common environment and morphological homoplasy, and these distinctions tend to be irrelevant to true phylogenetic relationships. As a result, many species ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Thrips
Thrips ( order Thysanoptera) are minute (mostly long or less), slender insects with fringed wings and unique asymmetrical mouthparts. Different thrips species feed mostly on plants by puncturing and sucking up the contents, although a few are predators. Entomologists have described approximately 6,000 species. They fly only weakly and their feathery wings are unsuitable for conventional flight; instead, thrips exploit an unusual mechanism, clap and fling, to create lift using an unsteady circulation pattern with transient vortices near the wings. Many thrips species are pests of commercially important crops. A few species serve as vectors for over 20 viruses that cause plant disease, especially the Tospoviruses. Some species of thrips are beneficial as pollinators or as predators of other insects or mites. In the right conditions, such as in greenhouses, many species can exponentially increase in population size and form large swarms because of a lack of natural predators ...

Panchaetothripinae is a subfamily of thrips in the family Thripidae, first described in 1912 by Richard Siddoway Bagnall. There are about 11 genera and more than 50 described species in Panchaetothripinae.

Thripinae
The Thripinae are a subfamily of thrips, insects of the order Thysanoptera. The Thripinae belong to the common thrips family Thripidae and include around 1,400 species in 150 genera. A 2012 molecular phylogeny found that the Thripinae was paraphyletic; further work will be needed to clarify the relationships within the group. Notable members – some of them economically significant pests – are for example '' Anaphothrips susanensis'', '' Megalurothrips distalis'', '' Sciothrips caramomi'', ''Scirtothrips dorsalis'' (chili thrips), '' Sorghothrips jonnaphilus'', '' T. hawaiiensis'', '' T. palmi'' (melon thrips) and '' T. tabaci'' (onion thrips). The subfamily includes many pests, some of them invasive species. The chili thrips, ''Scirtothrips dorsalis'', is an Asian pest on many crops, including chili peppers, roses, strawberry, tea, ground nuts, and castor bean. The western flower thrips, ''Frankliniella occidentalis'', has recently expanded its range from western North Am ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Taeniothrips Inconsequens
''Taeniothrips'' is a genus of insects belonging to the family Thripidae. The genus has almost cosmopolitan distribution In biogeography, cosmopolitan distribution is the term for the range of a taxon that extends across all or most of the world in appropriate habitats. Such a taxon, usually a species, is said to exhibit cosmopolitanism or cosmopolitism. The ext ....

Pear Thrips
Pears are fruits produced and consumed around the world, growing on a tree and harvested in the Northern Hemisphere in late summer into October. The pear tree and shrub are a species of genus ''Pyrus'' , in the family Rosaceae, bearing the pomaceous fruit of the same name. Several species of pears are valued for their edible fruit and juices, while others are cultivated as trees. The tree is medium-sized and native to coastal and mildly temperate regions of Europe, North Africa, and Asia. Pear wood is one of the preferred materials in the manufacture of high-quality woodwind instruments and furniture. About 3,000 known varieties of pears are grown worldwide, which vary in both shape and taste. The fruit is consumed fresh, canned, as juice, or dried. Etymology The word ''pear'' is probably from Germanic ''pera'' as a loanword of Vulgar Latin ''pira'', the plural of ''pirum'', akin to Greek ''apios'' (from Mycenaean ''ápisos''), of Semitic origin (''pirâ''), meaning "fruit ...

Insect Families
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. Inse ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Homoplasy
Homoplasy, in biology and phylogenetics, is the term used to describe a Phenotypic trait, feature that has been gained or lost independently in separate lineages over the course of evolution. This is different from Homology (biology), homology, which is the term used to characterize the similarity of features that can be parsimoniously explained by common ancestry. Homoplasy can arise from both similar selection pressures acting on adapting species, and the effects of genetic drift. Most often, homoplasy is viewed as a similarity in morphological characters. However, homoplasy may also appear in other character types, such as similarity in the genetic sequence, life cycle types or even behavioral traits. Etymology The term homoplasy was first used by Ray Lankester in 1870. The corresponding adjective is either ''homoplasic'' or ''homoplastic''. It is derived from the two Ancient Greek words (), meaning "similar, alike, the same", and (), meaning "to shape, to mold". Parall ...
