Abstract: Sterile insect technique is an effective tool to manage a range of pest insects, including the true fruit flies (Diptera: Tephritidae). As part of the process, pupae are dispatched from a mass‐rearing facility for several hundred km to a rearing out centre typically located near the release sites. Transportation of Queensland fruit fly (Qfly), Bactrocera tryoni (Froggatt), pupae from mass production facilities to field release sites is known to negatively affect fly quality. To determine which quality parameters are affected, we assessed adult emergence, flight ability, and rate of fliers between irradiated and non‐irradiated flies that were or were not transported long distance. Pupal weight was not affected by irradiation or transport. We found that transportation and irradiation of pupae resulted in a decrease in percentage fly emergence, flight ability, and fliers. Transportation and irradiation both resulted in 8% reduction in emergence of flies. Additionally, we found that transportation resulted in an increase in the rate of deformity by 65% and irradiation could increase deformity by 75%. Compounding these losses, both transportation and irradiation resulted in the decline of number of fliers by approximately 23% each.

Abstract: Tephritid fruit flies are major economic pests for fruit production and are an impediment to international trade. Different host fruits are known to vary in their suitability for fruit flies to complete their life cycle. Currently, international regulatory standards that define the likely legal host status for tephritid fruit flies categorize fruits as a natural host, a conditional host, or a nonhost. For those fruits that are natural or conditional hosts, infestation rate can vary as a spectrum ranging from highly attractive fruits supporting large numbers of fruit flies to very poor hosts supporting low numbers. Here, we propose a Host Suitability Index (HSI), which ides the host status of natural and conditional hosts into five categories based on the log infestation rate (number of flies per kilogram of fruit) ranging from very poor (& .1), poor (0.1–1.0), moderately good (1.0–10.0), good (10–100), and very good (& ). Infestation rates may be determined by field s ling or cage infestation studies. We illustrate the concept of this index using 21 papers that examine the host status of fruits in five species of polyphagous fruit flies in the Pacific region: Bactrocera tryoni Froggatt, Bactrocera dorsalis (Hendel), Bactrocera latifrons (Hendel), Zeugodacus cucurbitae (Coquillett), and Ceratitis capitata (Wiedemann) (Diptera: Tephritidae). This general-purpose index may be useful in developing systems approaches that rely on poor host status, for determining surveillance and detection protocols for potential incursions, and to guide the appropriate regulatory response during fruit fly outbreaks.

Abstract: Fruit flies are among the most destructive horticultural pests. For Queensland fruit fly (Qfly), Bactrocera tryoni (Froggatt) (Diptera: Tephritidae), the sterile insect technique (SIT) is the main control method used in southeastern Australia. SIT involves the mass rearing of Qfly, sterilisation of pupae by irradiation, transport to release centres, and release of sterile Qfly to disperse into the environment. Mating of sterile and wild flies results in no offspring thus, the wild population rapidly decreases. Previously, research has mainly focused on improvements within the production facility. However, transport from production facility to release sites is also an essential component in all SIT programs. Here, we examined historical records from the Victorian SIT program between 2002 and 2013 in three seasons (spring, summer, and autumn). We compared quality control (QC) data of irradiated fly pupae at the mass‐rearing facility in New South Wales (limited transport) to those of pupae transported to a release centre in Victoria (extensive transport). After extensive transport, pupal weight (−0.3 mg, or −3%) and flight ability (an overall 26% decline) were lower across all seasons, but particularly in spring. Adult emergence was lower across all seasons (an overall 23% decline), but particularly in summer. All three QC parameters were more variable after extensive transport. We discuss potential causes of the observed decreased pupal quality and avenues of future research to mitigate transport losses.

Abstract: The Host Reproduction Number (HRN) is a measure of the number of adult fruit flies that can emerge from one kilogram of fruit. HRN is a useful tool in surveillance, management and trade. I reviewed the literature for Queensland fruit fly (Qfly) and found data on 297 hosts. There were 81 Qfly hosts with HRN data and 216 Qfly hosts with no HRN data. The HRN will help to inform and triage hosts for target surveillance and management programs. Additionally, HRN will inform disinfestation activities pertaining to incursion response management, risk mitigation and trade options. There is a need for scientists to report HRN in a consistent manner so that Qfly management programs and trade protocols might be optimised.
