A list of the 356 species of Cecidomyiidae (Diptera) recorded from Finland is presented, which comprises 6 Lestremiinae, 156 Micromyinae, 16 Winnertziinae, 69 Porricondylinae, and 109 Cecidomyiinae. The faunistic knowledge of Finnish Winnertziinae, Porricondylinae and Cecidomyiinae is regarded as particularly poor. Based on species numbers known from other countries in Europe, a conservative estimate is 700–800 species of Cecidomyiidae actually occurring in Finland. 相似文献

Definitions are proposed for the independent and joint contributions that the chemical groups A and B make to the free energy of association of the ligand A?B with a receptor. The definitions are independent of the choice of the standard state and are consistent with the basic thermodynamic cycle relating the association of the ligands A?B, A?Y and X?B to the receptor Rappaport 1976. The basic idea is the use of the excess free energy of association of the ligand A?Y over the free energy of association of the reference ligand X?Y as the measure of the “independent” contribution of the group A to the binding. This definition allows the free energy of association of the ligand A?B to be written as the sum of the independent contributions of the groups A and B, their joint contribution, and an invariant free energy of association of the reference ligand with any receptor. With the appropriate definition of the receptor-reference ligand complex, water can be chosen as the reference ligand. Using ΔG(A?OH)?AG(HOH), ΔG(H?B?H)?ΔG(HOH) and ΔG(HO?C)?ΔG(HOH) as the definitions of the “independent” contributions of the chemical groups A, B and C to the binding of the ligand A?B?C, the joint contribution of the groups A and C to the binding is ΔG(A?B?C) ? ΔG(A?B?H) ? ΔG(H-B-C) + ΔG(H?B?H). 相似文献

The expected rate of allelism, E[I(x)], of lethal genes between two colonies with distance x in a structured population is studied by using one- and two-dimensional stepping-stone models. It is shown that E[I(x)] depends on the magnitude of selection in heterozygous condition (h), the rate of migration among adjacent colonies (m), the number of loci which produce lethal mutations (n) and the effective population size of each colony (N).——E[I(x)] always decreases with distance x. The rate of decrease is affected strongly by the magnitude of m. The rate of decrease is faster when m is small. E[I(x)] also decreases with increasing N and n. The effect of h on E[I(x)] is somewhat complicated. However, E[I(0)] is always smaller when h is small than when it is large.——For large x, the following approximate formulae may be obtained: (see PDF) where q and Var (q) are the mean and the variance of gene frequencies in each colony, t is approximated as t=h, (see PDF), -h for the partially recessive, completely recessive, and overdominant lethals, respectively, and C0 is a function of m and t. It is clear that E[I(x)] declines exponentially with x in a one-dimensional habitat. The decrease E[I(x)] is faster in a two-dimensional habitat than in a one-dimensional habitat. The present result is applied to some of the existing data and the estimation of population parameters is also discussed. 相似文献

Soil-transmitted helminths are parasitic nematodes that inhabit the human intestine. These parasites, which include two hookworm species,
Ancylostoma
duodenale
and Necator americanus, the whipworm
Trichuris
trichiura
, and the large roundworm
Ascaris
lumbricoides
, infect upwards of two billion people and are a major cause of disease burden in children and pregnant women. The challenge with treating these diseases is that poverty, safety, and inefficient public health policy have marginalized drug development and distribution to control infection in humans. Anthelmintics (anti-worm drugs) have historically been developed and tested for treatment of non-human parasitic nematodes that infect livestock and companion animals. Here we systematically compare the in vitro efficacy of all major anthelmintic classes currently used in human therapy (benzimidazoles, nicotinic acetylcholine receptor agonists, macrocyclic lactones, nitazoxanide) against species closely related to human parasitic nematodes-Ancylostoma ceylanicum,
Trichuris
muris
, and
Ascaris
suum
--- as well as a rodent parasitic nematode used in veterinary drug discovery,
Heligmosomoides
bakeri
, and the free-living nematode Caenorhabditis elegans. Extensive in vitro data is complemented with single-dose in vivo data in three rodent models of parasitic diseases. We find that the effects of the drugs in vitro and in vivo can vary greatly among these nematode species, e.g., the efficacy of albendazole is strong on A. ceylanicum but weak on
H
. bakeri
. Nonetheless, certain commonalities of the in vitro effects of the drugs can be seen, e.g., nitazoxanide consistently shows an all-or-nothing response. Our in vitro data suggest that further optimization of the clinical efficacy of some of these anthelmintics could be achieved by altering the treatment routine and/or dosing. Most importantly, our in vitro and in vivo data indicate that the hookworm A. ceylanicum is a particularly sensitive and useful model for anthelmintic studies and should be incorporated early on in drug screens for broad-spectrum human soil-transmitted helminth therapies. 相似文献

The present checklist includes data on the species composition, geographic distribution and feeding preferences of thrips species in Bulgaria. In total, 155 species in 48 genera are listed. Of these, 125 species belong to suborder Terebrantia and include 103 species of 33 genera in family Thripidae, 14 species of two genera in Aeolothripidae, seven species of two genera in Melanthripidae and one species in Fauriellidae. In suborder Tubulifera, 30 species of 10 genera in the single family Phlaeothripidae are listed. Of the 155 Bulgarian thrips species, 87.7% are phytophagous, 4.5% are obligate predators, 5.8% are mycophagous and 1.9% are with unknown feeding preferences. Fourteen pest species are listed for Bulgaria, of which Frankliniella
occidentalis, Thrips
tabaci and Haplothrips
tritici are of economic importance. The list provides detailed information on the horizontal and vertical distribution of Thysanoptera in 5 regions and 45 subregions of Bulgaria. The present paper also includes an evaluation of the biodiversity of Thysanoptera and the extent to which each region of the country has been studied. 相似文献

The photo-oxygenation of ethyl 2-methyl-5-(1,2,3,4-tetra-O-acetyl-d-lyxo-tetritol-1-yl)-3-furoate, ethyl 2-methyl-5-(1,2,3,4-tetra-O-acetyl-d-arabino-tetritol-1-yl)-3-furoate, 3-acetyl-2-methyl-5-(1,2,3,4-tetra-O-acetyl-d-arabino-tetritol-1-yl)furan, and ethyl 5-(1,4-di-O-acetyl-2,3-O-isopropylidene-d-lyxo-tetritol-1-yl)-2-methyl-3-furoate yielded the corresponding 1,4-endo-peroxides (3a–3d as pairs of diastereomers). Each diastereomer of the pairs 3a and 3d was isolated by fractional crystallisation. The rearrangement of the endo-peroxides at room temperature, by dissolution in CDCl3, yielded the corresponding diepoxides and monoepoxides. The reduction of 3a–3d with methyl sulphide yielded the corresponding γ-diketones, ethyl (E)-2-C-acetyl-5,6,7,8-tetra-O-acetyl-2,3-dideoxy-d-lyxo-oct-2-en-4-ulosonate, ethyl (E)-2-C-acetyl-5,6,7,8-tetra-O-acetyl-2,3-dideoxy-d-arabino-oct-2-en-4-ulosonate, 3-C-acetyl-6,7,8,9-tetra-O-acetyl-1,3,4-trideoxy-d-arabino-non-3-eno-2,5-diulose, and ethyl (E)-2-C-acetyl-5,8-di-O-acetyl-2,3-dideoxy-6,7-O-isopropylidene-d-lyxo-oct-2-en-4-ulosonate, which can isomerise into the corresponding Z isomers. 相似文献

This paper launches an open access DNA barcoding project “AUSBS” under the Barcoding of Life Datasystems (BOLD). The aims of the project are to help scientists who lack the necessary morphological knowledge to identify known species using molecular markers, to aid native bee specialists with the recognition of species groups that morphologically are difficult to define, and, eventually, to assist with the recognition of new species among known species. Using integrative taxonomy, i.e. morphological comparison to type specimens in Australian museum collections combined with phylogenetic analysis of a fragment of the mitochondrial DNA cytochrome c oxidase subunit I (mtCOI) gene sequences led to the recognition of four new species of Euhesma Michener (Hymenoptera: Colletidae: Euryglossini) collected during intensive surveys in remote Australian conservation areas, which are described. The new species are Euhesma
micans, Euhesma
lyngouriae, and Euhesma
aulaca in a species group associated with Eremophila flowers, and Euhesma
albamala in the walkeriana species group. 相似文献

The genus Hisonotus was resurrected as a member of the tribe Otothyrini (actually subfamily Otothyrinae). However, phylogenetic studies based on morphological and molecular data showed that Hisonotus is not monophyletic and independent lineages can be identified, such as the group composed of the species Hisonotus
insperatus, Hisonotus
luteofrenatus, Hisonotus
oliveirai, Hisonotus
paresi and Hisonotus
piracanjuba, a lineage unrelated to that containing the type species of the genus Hisonotus (Hisonotus
notatus). Herein, based in molecular and morphological data, a new genus is described to accommodate the lineage mentioned above, into which are also added three new species. This new genus can be distinguished from other genera of Otothyrinae by the following combination of characters: (1) a pair of rostral plates at the tip of the snout; (2) two large pre-nasal plates just posterior to the rostral plates; (3) a supra-opercular plate that receives the laterosensory canal from the compound pterotic before the preopercle; (4) a well developed membrane at anal opening in females; and (5) a V-shaped spinelet. A key to species of Curculionichthys is provided. 相似文献

The Australian harvestmen genus Megalopsalis (Neopilionidae: Enantiobuninae) is recognised as a senior synonym of the genera Spinicrus and Hypomegalopsalis, and seven new species are described in Megalopsalis: Megalopsalis suffugiens, Megalopsalis walpolensis, Megalopsalis caeruleomontium, Megalopsalis atrocidiana, Megalopsalis coronata, Megalopsalis puerilis and Megalopsalis sublucens. A morphological phylogenetic analysis of the Enantiobuninae is also conducted including the new species. Monophyly of Neopilionidae and Enantiobuninae including ‘Monoscutidae’ is corroborated, with the Australasian taxa as a possible sister clade to the South American Thrasychirus. 相似文献

The Chinese species of the genera Omicrogiton Orchymont, 1919, Peratogonus Sharp, 1884 and Mircogioton Orchymont, 1937 are reviewed, diagnosed and keyed. Mircogioton and Omicrogiton are reported for the first time from China, Peratogonus for the first time for mainland China. Five species are recognized: Omicrogiton
coomani Balfour-Browne, 1939 (Guangdong, Hongkong), Omicrogiton
hainanensis
sp. n. (Hainan), Omicrogiton
roberti
sp. n. (Hainan), Mircogioton
coomani Orchymont, 1937 (Yunnan), and Peratogonus
reversus Sharp, 1884 (Guangdong, Jiangxi, Taiwan). Lectotype of Omicrogiton
coomani is designated. Mircogioton
cognitus (Malcolm, 1981), syn. n. is considered a junior subjective synonym of Mircogioton
coomani Orchymont, 1939. Species of Mircogioton and Omicrogiton inhabit decaying banana trunks, whereas Peratogonus
reversus was always collected from moist forest leaf litter. 相似文献

6-O-Benzyl-7,8-dideoxy-1,2:3,4-di-O-isopropylidene-l-glycero-α-d-galacto-oct-7-ynopyranose reacted with tributyltin hydride to afford (Z-6-O-benzyl-7,8-dideoxy-1,2:3,4-di-O-isopropylidene-8-(tributylstannyl)-l-glycero-α-d-galacto-oct-7-enopyranose, which was subsequently isomerized to the E-olefin 4. Replacement of the tributyltin moietey with lithium in 4 afforded the vinyl anion which reacted with 3-O-benzyl-1,2-O-isopropylidene-α-d-xylo-pentodialdo-1,4-furanose, furnishing 3-O-benzyl-6-C-[(E)-6-O-benzyl-7-deoxy-1,2:3,4-di-O-isopropylidene-l-glycero-α-d-galacto-heptopyranos-7-ylidene] -60-deoxy-1,2-O-isopropylidene-α-d-gluco- (6) and -β-l-ido-furanose (7) in yields of ∼70 or ∼87% (depending on the temperature of the reaction). The configurations of the new chiral centers in 6 and 7 were determined by their conversion into 3-O-benzyl-1,2-O-isopropylidene-α-d-gluco- and -β-l-ido-furanose, respectively. Oxidation of 6 and 7 gave the same enone, 3-O-benzyl-6-C-[(E)-6-O-benzyl-7-deoxy-1,2:3,4-di-O-isopropylidene-l-glycero-α-d-galacto- heoptopyranos-7-ylidene]-6-deoxy-1,2-O-isopropylidene-α-d-xylo-hexofuranos-5-ulose. 相似文献
