“…One example is the El Pino mass-rearing facility in Guatemala that produces sterile male Mediterranean fruit flies which in addition to local use, are shipped and released in southern Mexico, Florida and California, USA [ 15 ]. Another example is the Mediterranean fruit fly facility in Valencia, Spain, that has the potential to provide sterile male flies to other European regions, such as Croatia, where the SIT is in corporated in an AW-IPM programme in the Nereva River Valley to manage a local Mediterranean fruit fly population [ 16 , 17 ]. Production of sterile insects in one location and release in a different one can only be successful when there are no mating barriers between the sterile and the wild males and when the sterile males are competitive with the native wild males for matings with the wild females.…”

The olive fruit fly, Bactrocera oleae (Rossi), is the most important insect pest for the cultivation of olives worldwide. Considerable research efforts have been invested in the past decades to develop eradication or suppression tactics for use within an area-wide integrated pest management (AW-IPM) approach that includes a sterile insect technique (SIT) component. One of the major obstacles encountered in the development of SIT for olive fruit fly was the inferior quality of the mass-reared flies, expressed among others evident primarily by sterile males having a different timing of peak mating and a lower mating propensity in comparison with their wild counterparts. In this study we assessed the mating behaviour and mating compatibility of olive fruit flies originating from four countries of the Mediterranean region (Croatia, France, Italy, Spain) in walk-in field cages and post zygotic compatibility (expressed as % egg hatch) under laboratory conditions. Furthermore, we tested the hypothesis whether a hybrid strain (Greece (domesticated)/Israel (wild)) adapted to laboratory rearing conditions showed any mating barriers with all the four “wild” populations. Finally, we examined the effect of colonization on the mating compatibility of the four newly established populations over three consecutive generations. The results showed no pre-zygotic (mating barriers) or post-zygotic isolations (measured by egg hatch%) among the olive fruit fly populations from the four countries tested. Also, there was no evidence of mating barriers between the hybrid strain and the wild populations of the Mediterranean region.

“…Previously, aerial releases of sterile insects involved dosing known volumes of insects into biodegradable release cartons prior to transportation. This approach minimised handling and potential damage (Bjelis et al, 2013). More recently, a new continuous release system has been developed to replace the conveyor belt method.…”

Developing optimal conditions for handling and transport of sterile male mosquitoes, prior to their release, is critical for the sterile insect technique (SIT) to be successful. No data currently exist for Anopheles arabiensis Patton (Diptera: Culicidae) concerning the effects of chilling at different temperatures and for different time lengths on subsequent survival. Additionally, it must be determined whether immobile mosquitoes are capable of producing metabolic heat, the maximum packing density in one release cassette during transport, and their toleration level to compaction. Male An. arabiensis were exposed to 2, 4, 6, and 10°C for 1, 4, 8, or 24 h. Survival was then monitored for 14 days and compared with untreated controls maintained at 25°C. Short-term (24 h) survival was assessed following immobilisation at 6°C for 6 h under compacted and non-compacted conditions and compared with non-immobilised controls. The experiment was repeated to assess long-term (1-14 days) survival with varying levels of ventilation. Metabolic heat was assessed in immobilised males (compacted and non-compacted) and compared with males maintained at 28°C for 2 h. The weight and volume of males were determined to guide the design of the release cassette. Male An. arabiensis were maintained at a temperature range of 4-10°C for 24 h without any significant negative effect on their survival. Compaction did not significantly affect survival; however, it fared better with increased ventilation. Immobile males did not produce any metabolic heat, even when compacted. This study identified initial parameters considered critical for the transport of sterile male An. arabiensis prior to release without any detrimental effect on their survival. Further investigation is required to assess the effects of combining these chosen treatments with irradiation. Additionally, the effect of immobilisation, compaction, and irradiation on the most critical parameter for SIT (male competitiveness) is the subject of future studies.

The sterile insect technique (SIT) is being applied against fruit fly pests in many areas of the world. Currently, factories have a capacity to produce several billion sterile insects per week, to irradiate them and to make them available for shipment to their destinations. There the emerging flies are fed and maintained for various periods of time in fly emergence and release facilities, and then collected for release. While much research effort has been invested in improving mass rearing and quality control procedures at the fly factory level, the post‐factory handling of sterile flies has received much less attention. A 6‐year FAO/IAEA Coordinated Research Project (CRP) was initiated with the participation of 31 research institutes from 17 countries to assess and validate ways to improve sterile male performance through better management during the critical period that starts with the arrival of pupae at the fly emergence and release facility and ends with the release of the sterile flies in the field. This review summarizes the research that was conducted under the CRP focusing on fruit fly species from the genera Anastrepha, Bactrocera and Ceratitis against which the SIT is being applied. To increase the effectiveness of SIT programmes, exposure of sterile males to nutritional, hormonal and semiochemical supplements was assessed and improved handling and release methods tested. Incorporation of protein and juvenile hormone into pre‐release diets significantly accelerated sterile male maturation and improved sexual performance among several species, while semiochemical treatments using ginger root oil or citrus oils in Ceratitis capitata and methyl eugenol in Bactrocera dorsalis complex species significantly increased sterile male mating competitiveness. Improved fly emergence, holding and release procedures were also assessed, together with the compilation of all this knowledge into a manual. Several of these findings have been transferred to and are being applied in operational programmes.
