Adults, nymphs, larvae and eggs of Gallilichus jonesi sp. n. are described. These mites inhabit the quills of large wing and tail feathers of the megapode Alectura lathami Gray, where they appear to consume the spongy medulla inside the quill. This is the first record of Gallilichus for Australia, and the first observation of quill mites associated with the Megapodiidae. Two nymphal morphologies of G. jonesi were observed and are presumed to represent male and female, but because pharate adults were not found, definitive assignment of morphs to sexes was not possible. The only other species in the genus Gallilichus occurs in the feathers of domestic chickens. The implications of these host-associations for elucidating relationships between the megapodes and other galliform birds are discussed. 相似文献

A phylogeny of the megapodes (Aves: Megapodiidae) based on nuclear and mitochondrial DNA sequences 总被引:6,自引:0,他引:6
DNA sequences from the first intron of the nuclear gene rhodopsin (RDP1) and from the mitochondrial gene ND2 were used to construct a phylogeny of the avian family Megapodiidae. RDP1 sequences evolved about six times more slowly than ND2 and showed less homoplasy, substitution bias, and rate heterogeneity across sites. Analysis of RDP1 produced a phylogeny that was well resolved at the genus level, but RDP1 did not evolve rapidly enough for intrageneric comparisons. The ND2 phylogeny resolved intrageneric relationships and was congruent with the RDP1 phylogeny except for a single node: this node was the only aspect of tree topology sensitive to weighting in parsimony analyses. Despite differences in sequence evolution, RDP1 and ND2 contained congruent phylogenetic signal and were combined to produce a phylogeny that reflects the resolving power of both genes. This phylogeny shows an early split within the megapodes, leading to two major clades: (1) Macrocephalon and the mound-building genera Talegalla, Leipoa, Aepypodius, and Alectura, and (2) Eulipoa and Megapodius. It differs significantly from previous hypotheses based on morphology but is consistent with affiliations suggested by a recent study of parasitic chewing lice. 相似文献

The singing honeyeater, a nectar-feeding bird, is common throughout most of Australia. There is considerable geographical variation in weight, the heaviest birds (30 g) living at the highest latitudes (35°S) and the lightest birds (19 g) at the lowest latitudes (16°S). Clinal variation in weight is apparently related to climatic factors (e.g. potential evapotranspiration) in accord with Bergmann's rule. The exceptions are populations on islands and peninsulas which are about 13% heavier than those on the adjacent mainland. 相似文献

New feather mites of the family Pterolichidae (Acari: Pterolichoidea) from parrots (Aves: Psittaciformes) in Australia 总被引:1,自引:0,他引:1
Abstract Seven new feather mite species of the family Pterolichidae are described from various Australian parrots: Apexolichus lathami sp. n. from the swift parrot, Lathamus discolor (Shaw); Titanolichus platycerci sp. n. and Rhytidelasma punctata sp. n. from the pale-headed rosella, Platycercus adscitus (Latham); R. striata sp. n. from the Australian king-parrot, Alisterus scapularis (Lichtenstein); Lorilichus stenolobus sp. n. and Lorilichus curvilobus sp. n. from the rainbow lorikeet, Trichoglossus haematodus (Linnaeus); Psittophagus galahi sp. n. from the galah, Eolophus roseicapillus (Vieillot). We give a brief overview of taxonomic studies of pterolichid mites living on Psittaciformes, and discuss the main diagnostic characters of different generic groups of these mites. 相似文献

A representative of the family Apionacaridae is recorded from the passerine birds Passeriformes for the first time. Fringillosphaera bochkovi gen. n., sp. n. is described from the chaffinch Fringilla coelebs (Fringillidae). The new genus obtains main diagnostic characters as follows. Vertical setae vi absent. Prodorsal shield free from scapular sheilds and epimerites Ia. Humeral sheilds present. Epimerites I convergent, connected by sclerotized plate. Lateral setae f2 and pseudanal setae ps3 absent. Coxal fields I-IV sclerotized. In male: legs IV present, genital apparatus at level of trochanters IV, genital arch with divergent branches. Epiandrium absent. Coxal setae 3a absent. Morphological peculiarities, host associations and phylogenetic relationships of the family Apionacaridae are briefly discussed. It is suggested that this family represents and ancient and relic phylogenetic branch, which had split rather early from the common ancestor of the superfamily Analgoidea in the period of formation of the Neognathae birds. 相似文献

Tinamiphilopsis ariconte n. sp., a syringophilid mite, is described from three tinamou species (Tinamidae), Rhynchotus rufescens (Temminck) and Nothura
boraquira (Spix) in Paraguay and N.
minor (Spix) in Brazil. These data indirectly support the hypothesis that the cheyletoid-like predatory ancestor of the Syringophilidae
switched to parasitism before the divergence of the avian hosts into the two major clades Palaeognathae and Neognathae. 相似文献

The responses of Tetranychus urticae Koch from Australian cotton to chlorfenapyr has been monitored since the 1997–1998 growing season. Resistance was first detected in the 2001–2002 season and then increased quickly in both level and proportion of resistant strains detected. In response, the resistance management strategy for chlorfenapyr use in cotton was altered and now recommends a further restriction of use from two to one spray per season. There was no evidence of negative cross-resistance to the pyrethroid bifenthrin, but chlorfenapyr was associated with an undefined negative cross-resistance. 相似文献

The louse genus Carduiceps Clay & Meinertzhagen, 1939 is widely distributed on sandpipers and stints (Calidrinae). The current taxonomy includes three species on the Calidrinae (Carduiceps meinertzhageni, Carduiceps scalaris, Carduiceps zonarius) and four species on noncalidrine hosts. We estimated a phylogeny of four of the seven species of Carduiceps (the three mentioned above and Carduiceps fulvofasciatus) from 13 of the 29 hosts based on three mitochondrial loci, and evaluated the relative importance of flyway differentiation (same host species has different lice along different flyways) and flyway homogenization (different host species have the same lice along the same flyway). We found no evidence for either process. Instead, the present, morphology‐based, taxonomy of the genus corresponds exactly to the gene‐based phylogeny, with all four included species monophyletic. Carduiceps zonarius is found both to inhabit a wider range of hosts than wing lice of the genus Lunaceps occurring on the same group of birds, and to occur on Calidris sandpipers of all sizes, both of which are unexpected for a body louse. The previously proposed family Esthiopteridae is found to be monophyletic with good support. The concatenated dataset suggests that the pigeon louse genus Columbicola may be closely related to the auk and diver louse genus Craspedonirmus. These two genera share some morphological characters with Carduiceps, but no support was obtained for grouping these three genera together. Based on mitochondrial data alone, the relationships among genera within this proposed family cannot be properly assessed, but some previously suggested relationships within this proposed family are confirmed. 相似文献

Lorilichus n. g. (Pterolichidae, Pterolichinae) is restricted to the Indo-Australian parrots of the family Loriidae. Assigned to this new genus are Pterolichus (Pseudalloptes) species described by Trouessart in 1884, namely, lobiger (type-species), delibativentris, discifer, cultriventris, emargiventris and securiventris. The first three named species are illustrated and two new species, parvifolius and grandifolius, are described: the five species are from Lorius domicellus (L.). 相似文献

Abstract The biology of the Australian phytoseiid mite Typhlodromalus lailae is described from material collected in Western Australia and New South Wales in 1994. At 25°C, when fed on cumbungi ( Typha sp.) pollen, the life cycle is completed in approximately 6 days, with an intrinsic rate of natural increase ( r m ), of 0.38. Female−male pairs produced a mean total of 44.6 eggs within 22 days of oviposition, with 39% of these females living in excess of 29 days. Females that were deprived of males after first mating stopped laying eggs after 4−9 days, but if another male was added they resumed egg laying and produced close to a full complement of eggs (mean 42 eggs). At 25°C, fecundity on a diet of cumbungi pollen or thrips larvae (first-instar Frankliniella schutzei Trybom) was high, averaging 3.71 and 3.33 eggs per day, respectively, over a 3-day period. The sex ratio was approximately 1.5 females to 1 male. Consumption rate of thrips was also high, with an average of approximately seven first-instar or two second-instar F. schultzei larvae eaten per day. The species was also observed to feed on broad mite, Polyphagotarsonemus latus (Banks), and tomato russet mite, Aculops lycopersici (Massee). No diapause was observed under conditions of 25°C 8 h light and 10°C 16 h dark. Eggs were sensitive to low humidity, with 50% failing to hatch below 71.1% relative humidity. This species is of interest as a candidate biological control agent for thrips, broad mite and tomato russet mite in protected crops. 相似文献
