First report of phytoplasma disease in capsicum, celery and chicory in Queensland, Australia

Tomato big bud phytoplasma (16SrII-E group), a widely distributed phytoplasma in Australia, was detected in celery, capsicum and chicory plants from southern Queensland, Australia in February 2002.

First record of a smut fungus on Byblidaceae: Yelsemia lowrieana, a new species from Australia.

Yelsemia lowrieana sp . nov. (Ustilaginomycetes) is described and illustrated from Byblis rorida collected in northwestern Western Australia. Infected plants had galls filled with spores on stems and pedicels. The spores were unusual in that each could be separated from a dark outer spore wall. This is the first record of a smut fungus on the dicotyledonous host family Byblidaceae.

Survival and Growth of Damara, Dorper, Dorset, Rambouillet, South African Meat Merino First Cross Lambs in Semi Arid Queensland

The recent introduction to Australia of superior sheep meat breeds from South Africa provides a basis for improving the quality and amount of sheep meat grown in Queensland’s semi arid area. Alternatively suitable breeds from existing Australian stocks of dual purpose and traditional terminal meat sheep may bring the desired attributes required by the market place. There has been no critical assessment of sheep meat breeds suitably adapted to the rangeland environment of western Queensland.

First report of Tomato spotted wilt virus in chickpea (Cicer arietinum) in Australia

Tomato spotted wilt virus (genus Tospovirus) is recorded on chickpea (Cicer arietinum) in Australia for the first time. It caused shoot tip symptoms of wilting, necrosis, bunching and chlorosis, followed by premature death of plants.

First record of Passalora calotropidis in Australia and its generic position

Passalora calotropidis has been found for the first time in Australia on rubber bush (Calotropis procera) in northern Queensland where it was associated with a damaging leaf spot disease. Analysis of sequence data of the ITS region indicated that P calotropidis belonged to a group that consisted of species of Pseudocercospora. The generic position of P calotropidis and its potential for biological control are discussed.

First record of Nematospora coryli in Australia and its association with dry rot of Citrus

Nematospora (Eremothecium) coryli was isolated from Citrus and identified for the first time in Australia. This insect-transmitted yeast was associated with dry rot in cultivated and native Citrus fruits. Although N. coryli is known as a serious seed pathogen of many tropical and sub-tropical plants, evidence is presented that it has been present and undetected in Queensland for at least ninety years.

First records of the papaya strain of Papaya ringspot virus (PRSV-P) in French Polynesia and the Cook Islands

The papaya strain of Papaya ringspot virus (PRSV-P), the cause of papaya ringspot disease, was confirmed in French Polynesia and the Cook Islands by double antibody sandwich enzyme linked immunosorbent assay (DAS-ELISA). In French Polynesia, the virus has probably been on the islands of Tahiti and Moorea for several years, but appears not to have spread to eight other islands. In contrast, PRSV-P has only recently appeared in the Cook Islands and is now the subject of an eradication campaign.

First record of Erysiphe aquilegiae on a host outside the Ranunculaceae

Erysiphe aquilegiae (Erysiphaceae) is found for the first time on Catharanthus roseus, in the Apocynaceae. This fungus is previously known only on the Ranunculaceae. A detailed description of this teleomorphic Australian specimen is given, along with its rDNA internal transcribed spacer sequence. © Australasian Plant Pathology Society 2006.

First record of Aecidium sp. on Marsdenia sp. in Australia

Aecidium sp. (Pucciniaceae) on Marsdenia sp. is reported for the first time from Australia.

First fungal pathogen to be utilized for weed biocontrol in Fiji and Papua New Guinea

Biological control of weeds has been carried out in Fiji since 1911, when the seed-fly Ophiomyia lantanae was introduced in an attempt to control Lantana camara. In 1988, the thrips Liothrips mikaniae was introduced from Trinidad into the Solomon Islands in an attempt to undertake biocontrol of Mikania micrantha (mikania) in the Pacific. A small colony of the thrips was subsequently taken from the Solomon Islands to the Kerevat Lowlands Agricultural Experimental Station in New Britain, Papua New Guinea (PNG). Now two decades later and for the first time, a pathogenic rust fungus has been imported for use against mikania, one of Fiji’s and the Pacific’s worst invasive weeds.

First report of Colombian datura virus from Australia.

Colombian datura virus was identified from the ornamental plant Brugmansia sp., showing leaf mosaic symptoms. The nucleotide sequence of the 3 untranslated region and the amino acid sequence of the 3 portion of the coat protein were 100% identical to those from a Hungarian isolate of the virus. This represents the first record of this virus in Australia.

A review of Taenaris Hubner (Lepidoptera: Nymphalidae: Amathusiinae) in Queensland, together with first Australian records for T. myops kirschi Staudinger and Elymnias agondas melanippe Grose-Smith (Satyrinae).

Species of the amathusiine genus Taenaris Hubner known to occur in Australia, predominantly from Torres Strait, are reviewed and illustrated. T. myops kirschi Staudinger is recorded for the first time in Australia from four male specimens collected on Dauan Island, Torres Strait. A female specimen of the satyrine Elymnias agondas melanippe Grose-Smith also collected from Dauan Island represents the first record of this taxon from Australia. The high degree of variation observed in the external facies of Taenaris from Torres Strait and reliable taxonomic separation of female specimens are discussed. Taenaris-like forms of the papilionid, Papilio aegeus ormenus Guerin-Meneville and E. a. melanippe from Torres Strait and Dauan Island respectively are illustrated and reviewed. The form of P. a. ormenus from Torres Strait that is most similar to Taenaris spp. is identified as form ormenus Guerin-Meneville variety onesimus Hewitson.

First record of stubby-root nematode (Paratrichodorus porosus) associated with barley in Australia

High populations (5000 to 20 000/kg soil) of the stubby-root nematode Paratrichodorus porosus were identified morphologically from soil samples taken under patches of poorly growing barley in a field between Yuleba and Surat in western Queensland, Australia. Lower populations (<4000/kg soil) were recovered from soil samples taken from asymptomatic barley. This is the first record of this nematode species on barley in Australia.

The first five days: field and laboratory investigations during the early stages of the equine influenza outbreak in Australia, 2007.

Until August 2007, Australia was one of only three countries internationally recognised to be free of equine influenza (EI). This report documents the diagnosis of the first cases of EI in Australian horses and summarises the investigations that took place over the next 5 days. During that time, a multifocal outbreak was identified across eastern New South Wales and south-eastern Queensland. The use of an influenza type A pan-reactive real-time reverse transcription polymerase chain reaction allowed rapid confirmation of suspect cases of EI.

Evidence of bat origin for Menangle virus, a zoonotic paramyxovirus first isolated from diseased pigs

Menangle virus (MenPV) is a zoonotic paramyxovirus capable of causing disease in pigs and humans. It was first isolated in 1997 from stillborn piglets at a commercial piggery in New South Wales, Australia, where an outbreak of reproductive disease occurred. Neutralizing antibodies to MenPV were detected in various pteropid bat species in Australia and fruit bats were suspected to be the source of the virus responsible for the outbreak in pigs. However, previous attempts to isolate MenPV from various fruit bat species proved fruitless. Here, we report the isolation of MenPV from urine samples of the black flying fox, Pteropus alecto, using a combination of improved procedures and newly established bat cell lines. The nucleotide sequence of the bat isolate is 94% identical to the pig isolate. This finding provides strong evidence supporting the hypothesis that the MenPV outbreak in pigs originated from viruses in bats roosting near the piggery. © 2012 Printed in Great Britain.
