Pinewood movement restrictions

To minimise the spread of EHB in Western Australia (WA), restrictions on the movement of pinewood were implemented in 2006, and currently apply to areas where EHB occurs. By restricting the movement of pinewood from EHB infested areas, EHB has been contained to Restricted Movement Zones (RMZs) in the greater Perth metropolitan area.

The restrictions are described in the Agriculture and Related Resources Protection (European House Borer) Regulations 2006.

The regulations allowed for the establishment of quarantine zones, Priority Management Zones (PMZs) and RMZs, and placed restrictions not only on untreated pinewood movement from PMZs and RMZs …

Insecticide Resistance In Australian Spodoptera Frugiperda (J.E. Smith) And Development Of Testing Procedures For Resistance Surveillance, Lisa Bird, Melina M. Miles, Adam Quade, Helen Spafford

Biosecurity Research Articles

Spodoptera frugiperda (J.E. Smith) is a highly invasive noctuid pest first reported in northern Australia during early 2020. To document current status of resistance in S. frugiperda in Australia, insecticide toxicity was tested in field populations collected during the first year of establishment, between March 2020 and March 2021. Dose-response was measured by larval bioassay in 11 populations of S. frugiperda and a susceptible laboratory strain of Helicoverpa armigera. Emamectin benzoate was the most efficacious insecticide (LC50 0.023μg/ml) followed by chlorantraniliprole (LC50 0.055μg/ml), spinetoram (LC50 0.098μg/ml), spinosad (LC50 0.526μg/ml), and methoxyfenozide (1.413μg/ml). Indoxacarb was the least toxic …

Rabbit Control: Rhdv1 K5, Department Of Primary Industries And Regional Development, Western Australia

Biosecurity factsheets

The national release of the Korean strain of rabbit haemorrhagic disease virus, RHDV1 K5, took place during the first week of March 2017. It was the first time in 20 years a new rabbit biocontrol agent had been released into Australia, and was part of a 20-year national biocontrol plan for rabbits. More than 600 release sites were selected, including 110 sites in Western Australia (WA).

RHDV1 K5 is a naturally occurring Korean variant of the rabbit haemorrhagic disease virus (RHDV). Its release was expected to boost management and help slow the increase in rabbit numbers. RHDV1 K5 does not …

Native And Non-Native Sources Of Carbohydrate Correlate With Abundance Of An Invasive Ant, Lori Lach, Benjamin Hoffmann, Melinda L. Moir

Biosecurity Research Articles

Invasive species threaten many ecological communities and predicting which communities and sites are invasible remains a key goal of invasion ecology. Although invasive ants often reach high abundances in association with plant-based carbohydrate resources, the source and provenance of these resources are rarely investigated. We characterized carbohydrate resources across ten sites with a range of yellow crazy ant abundance in Arnhem Land, Australia and New Caledonia to determine whether yellow crazy ant (Anoplolepis gracilipes) abundance and trophic position correlate with carbohydrate availability, as well as the relative importance of native and non-native sources of carbohydrates to ant diet. …

The Role Of Flies As Pollinators Of Horticultural Crops: An Australian Case Study With Worldwide Relevance, David F. Cook, Sasha C. Voss, Jonathan T D Finch, Romina C. Rader, James M. Cook, Cameron J. Spurr

Horticulture Research Articles

Australian horticulture relies heavily on the introduced managed honey bee, Apis mellifera Linnaeus 1758 (Hymenoptera: Apidae), to pollinate crops. Given the risks associated with reliance upon a single species, it would be prudent to identify other taxa that could be managed to provide crop pollination services. We reviewed the literature relating to the distribution, efficiency and management potential of a number of flies (Diptera) known to visit pollinator-dependent crops in Australia and worldwide. Applying this information, we identified the taxa most suitable to play a greater role as managed pollinators in Australian crops. Of the taxa reviewed, flower visitation by …

A Historical Review Of Management Options Used Against The Stable Fly (Diptera: Muscidae), David F. Cook

Animal production and livestock research articles

The stable fly, Stomoxys calcitrans (L.) (Diptera: Muscidae), remains a significant economic pest globally in situations where intensive animal production or horticultural production provide a suitable developmental medium. Stable flies have been recorded as pests of livestock and humans since the late 1800s to early 1900s. Over 100 years of research has seen numerous methodologies used to control this fly, in particular to protect cattle from flies to minimise production losses. Reduced milk production in dairy cows and decreased weight gain in beef cattle account for losses in the US alone of > $2000 million annually. Rural lifestyles and recreation are …

Burial And Compaction Of Sandy Soils To Prevent Emergence Of Adult Stable Fly (Diptera: Muscidae) At The Soil Surface, David F. Cook, Robert A. Deyl, Jeremy B. Lindsey, Mario F. D'Antuono, Don Telfer, Ian R. Mcpharlin

Horticulture Research Articles

Stable fly (Stomoxys calcitrans L.) remain a significant pest affecting livestock and rural communities on the Swan Coastal Plain around Perth, Western Australia. Vegetable crop residues remaining after harvest enable stable fly development. Left untreated they can produce from several hundred to >1,000 stable fly/m2 of post-harvest residues. We studied the effect of burial and compaction of sandy soils on adult emergence of stable fly and house fly (Musca domestica L.) (Diptera: Muscidae). Adults of both fly species can move up through 50 cm of loose, dry sand, however at depths greater than 60 cm, emergence rapidly declines …

Development And Testing Of A Standardized Method To Estimate Honeydew Production, Melinda L. Moir, Michael Renton, Benjamin Hoffmann, Mei Chen Leng, Lori Lach

Biosecurity Research Articles

Honeydew production by Hemiptera is an ecologically important process that facilitates mutualisms and increases nutrient cycling. Accurate estimates of the amount of honeydew available in a system are essential for quantifying food web dynamics, energy flow, and the potential growth of sooty mould that inhibits plant growth. Despite the importance of honeydew, there is no standardized method to estimate its production when intensive laboratory testing is not feasible. We developed two new models to predict honeydew production, one based on insect body mass and taxonomic family, and one based on body mass and life stage. We tested the accuracy of …
