This has major implications for the sustainable production and market access of Australia’s multi-billion-dollar horticultural industry. Worldwide there are over 4,000 species of fruit flies in the family Tephritidae of which around 350 species are of economic importance. More than 300 species of fruit fly occur in Australia although only a few of these have been found to have any degree of economic impact, with Queensland fruit fly (Bactrocera tryoni) and Mediterranean fruit fly (Ceratitis capitata) being the species of primary economic concern. It is therefore important to distinguish between the species that pose a threat to production and domestic market access and those that do not, including exotic species. Australia is free from many species that impact horticultural production elsewhere. Neighbouring countries in south east Asia and the South Pacific are home to numerous species of fruit fly that pose an immediate incursion risk to Australia. Rapid diagnosis of these flies, should they arrive in Australia, is therefore a critical prerequisite to containing and eradicating the populations before they establish. The accurate identification of fruit flies is a key component of Australia’s biosecurity system. It underpins the domestic movement of fruit and vegetables, maintains international market access for Australian producers, and protects Australia’s borders from exotic pest incursion. This completely revised version of The Australian Handbook for the Identification of Fruit Flies (Version 3.1) (the handbook) has been compiled by diagnosticians for diagnosticians using some of the latest research outcomes and resources available. The handbook is a compilation of diagnostic information for 65 fruit fly species, most of which are exotic to Australia, including the non-tephritid fruit infesting Drosophila suzukii (spotted-wing Drosophila). The handbook is intended to facilitate rapid diagnosis of fruit fly species and be a comprehensive guide for Australian diagnosticians and field officers involved in maintaining, supporting and enhancing Australia’s biosecurity system. 2 ABOUT THIS HANDBOOK This publication is the product of the Plant Biosecurity Cooperative Research Centre (PBCRC) project Next Generation National Fruit Fly Diagnostics and Handbook PBCRC2147. The handbook draws together hundreds of new high definition fruit fly images as well as new molecular diagnostic tools generated from this research. A companion website Fruit Fly Identification Australia (fruitflyidentification.org.au) has also been developed. The website contains an expanded selection of high definition images as well as an updated description of the latest molecular techniques and protocols used for the identification of fruit flies. The website also includes a new multi-entry Lucid key for identifying the Dacini species as well as comprehensive printable data sheets and an interactive glossary. The handbook and website were developed to support Australia’s fruit fly researchers, academics, surveillance officers, diagnosticians and laboratory scientists with the hope that the sharing of information and experience, as well as the constructive communication that brings this knowledge base together, will continue to grow.

Each fruit fly species described is illustrated with a dorsal photograph annotated with important diagnostic characteristics. Additional photographs provide information about variation within species as well as head, leg and lateral views. Maps indicate published distribution information and notes on easily confused or similar species are provided to aid correct identification. Photographs were taken by project members at Queensland University of Technology. A classic representative specimen (matching the current written morphological description in the literature) from each species has been photographed from a variety of angles showing key diagnostic features. Images for each individual include a head view, full body dorsal view, full body lateral view, dorsal and ventral abdomen views and a dorsal scutum view. Slide mounted fore, mid and hind legs and left and right wings were also photographed. Intraspecific morphological variants were also photographed illustrating differences where they occur, principally associated with colour

    Khan et al. BMC Biotechnology 2019, 19(Suppl 2):94 https://doi.org/10.1186/s12896-019-0580-0 RESEARCH Open Access Potential of a fly gut microbiota incorporated gel-based larval diet for rearing Bactrocera dorsalis (Hendel) Mahfuza Khan1*, Kajla Seheli1, Md. Abdul Bari1, Nahida Sultana1, Shakil Ahmed Khan1, Khandokar Fahmida Sultana2 and Md. Anwar Hossain3 Abstract Background: The Oriental fruit fly, Bactrocera dorsalis (Hendel) (Diptera: Tephritidae), is an important polyphagous pest of horticultural produce. The sterile insect technique (SIT) is a proven control method against many insect pests, including fruit flies, under area-wide pest management programs. High quality mass-rearing process and the cost-effective production of sterile target species are important for SIT. Irradiation is reported to cause severe damage to the symbiotic community structure in the mid gut of fruit fly species, impairing SIT success. However, studies have found that target-specific manipulation of insect gut bacteria can positively impact the overall fitness of SIT-specific insects. Results: Twelve bacterial genera were isolated and identified from B. dorsalis eggs, third instars larval gut and adults gut. The bacterial genera were Acinetobacter, Alcaligenes, Citrobacter, Pseudomonas, Proteus, and Stenotrophomonas, belonging to the Enterobacteriaceae family. Larval diet enrichment with the selected bacterial isolate, Proteus sp. was found to improve adult emergence, percentage of male, and survival under stress. However, no significant changes were recorded in B. dorsalis egg hatching, pupal yield, pupal weight, duration of the larval stage, or flight ability. Conclusions: These findings support the hypothesis that gut bacterial isolates can be used in conjunction with SIT.

  • 9. Sterile Fly Release Densities
    56 Guidance for packing, shipping, holding and release of sterile flies in area-wide fruit fly control programmes 9. Sterile fly release densities STEP V OF PROCESS IN FLOW CHART IN APPENDIX 2 9.1 FACTORS TO CONSIDER FOR ESTABLISHMENT OF STERILE FLY DENSITY (FROM HENDRICHS ET AL. 2005) 9.1.1 Pest aggregation Aside from the absolute population density, the degree of population aggregation or dispersion is important. Sterile insects are often released by aircraft, and are thus distributed fairly homogeneously over the target area, irrespective of whether the target pest is distributed evenly or clumped. Pest insects with a clumped distribution require higher release rates (Barclay 2005) as compared with a homogeneous pest distribution, to obtain the required sterile to wild male ratios (Vreysen 2005), and thus pest aggregation also affects strategy selection and its cost. Only if the released insects can find the same aggregation sites and aggregate in a similar manner as wild insects, so that adequate sterile to wild male over-flooding ratios are obtained in those sites, is there no need to increase release rates to compensate for such clumping. 9.1.2 Sterile male longevity The density of the sterile male population in the field, which fluctuates in relation to the release frequency and the sterile male mortality rate, should not decrease below that needed to maintain the critical overflooding ratio (Figure 9.1, upper graph) (Barclay 2005; Kean et al. 2005). Therefore, the frequency of release and number of sterile males released has to be carefully assessed in relation to the average longevity or survival of the sterile males, to effectively avoid periods when insufficient sterile males are present in the field (Figure 9.1, lower graph).

  • Fijian Fruit Fly
    Fact sheet Fijian fruit fly What is the Fijian fruit fly? Fijian fruit fly (Bactrocera passiflorae) is a small fly that attacks a range of fruit including papaya. Like all fruit flies, it can cause a significant amount of damage to fruit and make fruit unmarketable. This pest has the potential to have a significant impact on the Australian papaya industry. What does it look like? The Fijian fruit fly has a black coloured body with a black abdomen and clear wings. It is approximately 6-8mm long. Accurate diagnosis requires expert 1 mm examination of the fly under a microscope. Museum Victoria, PaDIL Ken Walker Dorsal view of adult Fijian fruit fly What can it be confused with? At first glance most fruit flies are very similar. The Fijian fruit fly can be differentiated from other fruit flies by its predominantly black colour. If you see any unusual fruit flies consult an agronomist or contact the Exotic Plant Pest Hotline on 1800 084 881. What should I look for? Adult Fijian fruit flies are visible to the naked eye so you should keep a look out for small black coloured fruit flies, especially around fallen or damaged fruit. Traps placed in your orchard may also help you look for fruit flies. You should also look for distorted, dropped or rotten fruit as these symptoms can be Ken Walker Museum Victoria, PaDIL Ken Walker caused by fruit flies. Report any unusual fruit flies in Lateral view of Fijian fruit fly. Note: fly is predominantly black your orchard to the Exotic Plant Pest Hotline on in colour 1800 084 881.

  • Inventory and Review of Quantitative Models for Spread of Plant Pests for Use in Pest Risk Assessment for the EU Territory1
    EFSA supporting publication 2015:EN-795 EXTERNAL SCIENTIFIC REPORT Inventory and review of quantitative models for spread of plant pests for use in pest risk assessment for the EU territory1 NERC Centre for Ecology and Hydrology 2 Maclean Building, Benson Lane, Crowmarsh Gifford, Wallingford, OX10 8BB, UK ABSTRACT This report considers the prospects for increasing the use of quantitative models for plant pest spread and dispersal in EFSA Plant Health risk assessments. The agreed major aims were to provide an overview of current modelling approaches and their strengths and weaknesses for risk assessment, and to develop and test a system for risk assessors to select appropriate models for application. First, we conducted an extensive literature review, based on protocols developed for systematic reviews. The review located 468 models for plant pest spread and dispersal and these were entered into a searchable and secure Electronic Model Inventory database. A cluster analysis on how these models were formulated allowed us to identify eight distinct major modelling strategies that were differentiated by the types of pests they were used for and the ways in which they were parameterised and analysed. These strategies varied in their strengths and weaknesses, meaning that no single approach was the most useful for all elements of risk assessment. Therefore we developed a Decision Support Scheme (DSS) to guide model selection. The DSS identifies the most appropriate strategies by weighing up the goals of risk assessment and constraints imposed by lack of data or expertise. Searching and filtering the Electronic Model Inventory then allows the assessor to locate specific models within those strategies that can be applied.

In this edition, it is treated as a separate species (see below). Bayer computer code: RHAGCO EU Annex designation: I/A1 • Rhagoletis suavis Name: Rhagoletis suavis (Loew) Synonyms: Trypeta suavis Loew Bayer computer code: RHAGSU EU Annex designation: I/A1 HOSTS • Rhagoletis completa The principal hosts are Juglans spp. In North America, J. nigra, J. californica and J. hindsii are attacked (Bush, 1966). Under certain conditions peaches (Prunus persica) may be attacked (Bush, 1966) but the significance of this is not clear. Wild hosts are other Juglans spp. (Foote, 1981). In the EPPO region, the only economically significant host might be walnuts (J. regia). Although there was only one old record, possibly a misidentification, on this host in North America (Cresson, 1929), there were records of high levels of infestation of walnut fruits in 1991 in some Italian orchards. • Rhagoletis suavis Recorded from Juglans ailanthifolia, J. cinerea, J. nigra and walnuts (J. regia) (Bush, 1966). Peaches (Prunus persica) are also an occasional host (Dean, 1969). GEOGRAPHICAL DISTRIBUTION R. completa and R. suavis are indigenous to North America. The former species has very recently been introduced into the EPPO region and has become established in a limited area.
