Anabarhynchus Macquart 1848 is a species-rich genus of stiletto flies (Diptera: Therevidae) belonging to the subfamily Therevinae, with over 113 species described from Australia. These are diverse and abundant in Australia’s eucalypt woodland mallee habitats. Here we describe, diagnose illustrate further three new as follows: A. aurantilateralis sp. nov. halmaturinus nov., venabrunneis Kangaroo Island. bring total number Australian 116, 13 these known occur on
Abstract Background Parasitoid insects manipulate their hosts' physiology by injecting various factors into host upon parasitization. Transcriptomic approaches provide a powerful approach to study insect host-parasitoid interactions at the molecular level. In order investigate effects of parasitization an ichneumonid wasp ( Diadegma semiclausum ) on Plutella xylostella ), larval transcriptome profile was analyzed using short-read deep sequencing method (Illumina). Symbiotic polydnaviruses...
Abstract Despite progress in recent decades, the conservation management of insects and allied invertebrates Australia is challenging remains a formidable task against background poor taxonomic biological knowledge, limited resources (funds scientific expertise) relatively low level community engagement, education awareness. In this review, we propose new, strategic national approach for to complement build on existing actions increase awareness with general public government. A review all...
Abstract The diversity and abundance of native invertebrates is declining globally, which could have significant consequences for ecosystem functioning. Declines are likely to be at least as severe those observed vertebrates, although often difficult quantify due a lack historic baseline data limited monitoring effort. Lepidoptera well studied in Australia compared with other invertebrates, so we know that some species imperilled or declining. Despite this, few butterfly taxa explicitly...
Abstract We report the first discovery since 1970s of a new extant family ( A enigmatineidae fam.n. ) homoneurous moths, based on small Aenigmatinea glatzella sp.n . from K angaroo I sland off southern ustralia. It exhibits combination extraordinary anatomical characters, and, unlike most its larva is conifer‐feeder (stem mining in Callitris , C upressaceae). While adult's mouthparts are strongly regressed, evidence other morphological characters and B ayesian analysis 25 genetic loci...
Polydnaviruses are essential for the survival of many Ichneumonoid endoparasitoids, providing active immune suppression host in which parasitoid larvae develop. The Cotesia rubecula bracovirus is unique among polydnaviruses that only four major genes detected parasitized (Pieris rapae) tissues, and gene expression transient. Here we describe a novel C. (CrV3) encoding lectin monomer composed 159 amino acids, has conserved residues consistent with invertebrate mammalian C-type lectins....
Abstract Interactions among insect pests, crops and weeds are well recognised. In fact, the elimination of weed hosts outside crop is a common practice to control many insect-vectored viruses. However, little known about interactions native vegetation, whether plants may be used revegetate areas where have been eliminated as part horticultural management regimes. We Northern Adelaide Plains region (South Australia, Australia) model system study potential various plant taxa in hosting four...
Epiphyas postvittana (Walker, 1863), or light brown apple moth (LBAM), is a highly polyphagous native Australian species and major insect pest in vineyards. Dolichogenidea tasmanica (Cameron, 1912) the most abundant parasitoid of larval stages LBAM. The prime objective our study was to determine parasitism success D. on different E. postvittana. Additionally, we aimed find out if head capsule width could be used instar number by examining variability size each LBAM effect rearing temperature...
The response of eukaryotic cells to ionising radiation (IR)-induced double-strand DNA breaks is highly conserved and involves a repair mechanism characterised by the early phosphorylation histone protein H2AX (producing active form γH2AX). Although expression an induced γH2AX variant has been detected in Drosophila melanogaster, homologue not reported economically important fruit flies. We use Bactrocera tryoni (Diptera: Tephritidae, Queensland fly or 'Q-fly') investigate this with view...
ABSTRACT Exposure of insect larvae to sublethal concentrations crystal toxins from the soil bacterium Bacillus thuringiensis (Bt toxins) causes induction immune and metabolic responses that can be transmitted offspring by epigenetic inheritance mechanisms. Given elevated status carries significant developmental penalties, we wanted establish relationships between induction, tolerance toxin penalties. A laboratory culture Helicoverpa armigera was induced a bacterial suspension containing...
Abstract The green carpenter bee, Xylocopa aerata (Smith, 1851), has undergone a severe reduction in its distribution over the previous century, part because of habitat loss and fragmentation dependency on old‐growth heathland habitats. In 2007, last remaining South Australian population, Kangaroo Island, was negatively affected by shortage nesting substrate as consequence series large, intense wildfires. an attempt to prevent yet another extirpation this species, we developed artificial...
Abstract Due to local extinction, the endangered green carpenter bee ( Xylocopa aerata ) has a disjunct distribution in southeast of Australia. The species relies on dead softwood from small selection plant for making its nests. Habitat fragmentation, combined with deleterious fire events, is thought have negatively impacted nesting substrate availability and recolonisation chances. Here, we use MaxEnt algorithm model both current effect climate change scenarios X. four that provide most...
Polydnaviruses are endogenous particles that crucial for the survival of endoparasitoid wasps, providing active suppression immune function lepidopteran host in which wasp larvae develop. The Cotesia rubecula bracovirus (CrBV) is unique only four gene products detected larval ( Pieris rapae ) tissues and expression CrBV genes transient, occurring between 4 12 h post-parasitization. Two genes, CrV1 CrV3, have been characterized. a secreted glycoprotein has implicated depolymerization actin...
Abstract The Monterey pine aphid ( Essigella californica ) was accidentally introduced into Australia from the northern hemisphere before being detected in Canberra 1998. Feeding on some members of Pinaceae, including commercially important Pinus radiata , has now spread to almost all pine‐growing areas and is considered be an forestry pest. In 2005, a project commissioned import parasitoid, Diaeretus essigellae subject it host‐specificity testing with view releasing as biological control...
Dolichogenidea tasmanica (Hymenoptera: Braconidae) is the most commonly reared parasitoid from larval light brown apple moth (LBAM), Epiphyas postvittana (Lepidoptera: Tortricidae), feeding on grapevines in Australia. In order to evaluate efficiency of searching behaviour D. tasmanica, a laboratory study was undertaken determine how this wasp responds susceptible stages LBAM. Observations were made wind tunnel, which allowed express its full range behaviour. The and susceptibility LBAM...
