Leaf-rolling Weevil
The Attelabidae is a widespread family of weevils. They are among the primitive weevils, because of their straight antennae, which are inserted near the base of the rostrum. The prothorax is much narrower than the base of the elytra on the abdomen. Attelabidae and the related family Rhynchitidae are known commonly as the leaf-rolling weevils.Legalov, A. A. (2004)New data of the leaf-rolling weevils (Coleoptera: Rhynchitidae, Attelabidae) of the world fauna with description of 35 new taxons.''Baltic Journal of Coleopterology'' 4(1) 63-88. Rhynchitidae may be treated as subfamily Rhynchitinae of the Attelabidae. Some members of this family have long necks and may be called giraffe weevils, particularly ''Trachelophorus giraffa''. A few species are minor agricultural pests. The larvae of Rhynchitinae feed in flower buds, fruits, and terminal shoots, or are leaf miners. The subfamily Attelabinae are the true leaf rollers. The female cuts slits into leaves to deposit her eggs, and rol ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Systematic Biology
Biological systematics is the study of the diversification of living forms, both past and present, and the relationships among living things through time. Relationships are visualized as evolutionary trees (synonyms: cladograms, phylogenetic trees, phylogenies). Phylogenies have two components: branching order (showing group relationships) and branch length (showing amount of evolution). Phylogenetic trees of species and higher taxa are used to study the evolution of traits (e.g., anatomical or molecular characteristics) and the distribution of organisms (biogeography). Systematics, in other words, is used to understand the evolutionary history of life on Earth. The word systematics is derived from the Latin word '' systema,'' which means systematic arrangement of organisms. Carl Linnaeus used 'Systema Naturae' as the title of his book. Branches and applications In the study of biological systematics, researchers use the different branches to further understand the relationshi ...

Ribosomal DNA
Ribosomal DNA (rDNA) is a DNA sequence that codes for ribosomal RNA. These sequences regulate transcription initiation and amplification, and contain both transcribed and non-transcribed spacer segments. In the human genome there are 5 chromosomes with nucleolus organizer regions: the acrocentric chromosomes 13 (RNR1), 14 ( RNR2), 15 ( RNR3), 21 (RNR4) and 22 (RNR5). The genes that are responsible for encoding the various sub-units of rRNA are located across multiple chromosomes in humans. But the genes that encode for rRNA are highly conserved across the domains, with only the copy numbers involved for the genes having varying numbers per species. In Bacteria, Archaea, and chloroplasts the rRNA is composed of different (smaller) units, the large (23S) ribosomal RNA, 16S ribosomal RNA and 5S rRNA. The 16S rRNA is widely used for phylogenetic studies. Eukaryotes The rRNA transcribed from the approximately 600 rDNA repeats forms the most abundant section of RNA found in cells ...

Phylogenetic
In biology, phylogenetics (; from Greek φυλή/ φῦλον [] "tribe, clan, race", and wikt:γενετικός, γενετικός [] "origin, source, birth") is the study of the evolutionary history and relationships among or within groups of organisms. These relationships are determined by Computational phylogenetics, phylogenetic inference methods that focus on observed heritable traits, such as DNA sequences, protein amino acid sequences, or morphology. The result of such an analysis is a phylogenetic tree—a diagram containing a hypothesis of relationships that reflects the evolutionary history of a group of organisms. The tips of a phylogenetic tree can be living taxa or fossils, and represent the "end" or the present time in an evolutionary lineage. A phylogenetic diagram can be rooted or unrooted. A rooted tree diagram indicates the hypothetical common ancestor of the tree. An unrooted tree diagram (a network) makes no assumption about the ancestral line, and does ...

Trachelophorus
''Trachelophorus'' is a genus of weevils in the leaf-rolling weevil family Attelabidae. Several species are known as giraffe weevils because of their elongated "necks". The best known species is ''Trachelophorus giraffa''. Species include:''Trachylophorus''. EOL. *'''' *'''' *'''' *'' |
Euops
''Euops'' is a genus of the leaf-rolling weevils (family Attelabidae) containing more than 300 species. It is spread over most tropical and subtropical regions but is missing from America. The centre of its radiation is New Guinea and Australia where it is the only representative of the subfamily Attelabinae. Females of ''Euops'' have mycangia in the space between metathorax and abdomen. Leaf rolls prepared for oviposition are inoculated with spores from these mycangia. Moreover, the leaf-rolls are treated by the female using abdominal setose brushes that in most species apply secretions of unknown function. The fungus growing on a thus treated leaf-roll does not improve its nutritional value but may play a role as an antagonist of other microbes potentially harmful to the weevil larva A larva (; plural larvae ) is a distinct juvenile form many animals undergo before metamorphosis into adults. Animals with indirect development such as insects, amphibians, or cnidarians typ ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
