“…In the case of C. capitata, exposure to ginger (Zingiber officinale Roscoe) root oil or citrus oils (by contact or vapour) enhances considerably the mating competitiveness of wild or mass-reared males (Katsoyannos et al 1997;Papadopoulos et al 2001;Shelly 2001).…”

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.

“…Due to its commercial relevance, many studies focused on the development and improvement of different control strategies. Some of them are based on the use of biological competitors (Headrick and Goeden 1996) or sterile adults, as in the Sterile Insect Technique (SIT, Shelly and Kennelly 2002;Shelly and McInnis 2003;Shelly 2005), others on chemicals, such as the mass trapping (Jang et al 1989(Jang et al , 1994Heath et al 1991;Cossè et al 1995;Katsoyannos et al 1997;Papadopoulos et al 2001). Both SIT and mass trapping are more effective when they involve the activation of the olfactory system, since odorants can be used as efficient species-specific attractants.…”

Morphological characterization of the antennal lobes in the Mediterranean fruit fly Ceratitis capitata

et al. 2015

The medfly Ceratitis capitata is one of the most important pests for horticulture worldwide. The knowledge about anatomy and function of the medfly olfactory system is still limited. The first brain structure to process olfactory information in insects is the antennal lobe (AL), which is composed of its functional and morphological units, the olfactory glomeruli. Here, we present a morphological three-dimensional reconstruction of AL glomeruli in adult brains. We used unilateral antennal backfills of olfactory receptor neurons (ORNs) with neural tracers, revealing the AL structure. We recorded confocal stacks acquired from whole-mount specimens, and analyzed them with the software AMIRA. The ALs in C. capitata are organized in glomeruli which are more tightly packed in the anterior part than the posterior one. Axons of ORNs bilaterally connect the ALs through a commissure between the two ALs. This commissure is formed by several distinct fascicles. Contralateral dye transfer suggests the presence of gap junctions connecting ORNs from both antennae. There was no statistical difference between the average volumes of female ALs (204,166 ± 12,554 μm(3)) and of male ALs (190,287 ± 11,823 μm(3)). In most specimens, we counted 53 glomeruli in each AL, seven of which were sexually dimorphic in size

“…Accordingly, various approaches have been examined. These include protein supplements to the pre-release diet (Maor et al, 2004;Barry et al, 2007), Juvenile hormone treatments (Teal et al, 2000), probiotic diets (Niyazi et al, 2004), and aromatherapy (Papadopoulos et al, 2001;Shelly et al, 2003). However, with the exception of aromatherapy, none have been implemented on a large scale.…”

Manipulation of the microbiota of mass-reared Mediterranean fruit flies Ceratitis capitata (Diptera: Tephritidae) improves sterile male sexual performance

The sterile insect technique (SIT) is a method of biological control whereby millions of factory reared sterile male insects are released into the field. This technique is commonly used to combat the Mediterranean fruit fly (Ceratitis capitata, Diptera: Tephritidae). Sterile medfly males are less competent in attracting and mating with wild females, a property commonly linked to the irradiation process responsible for the sterilization. As bacteria are important partners in the fly's life cycle, we used molecular analytical methods to study the community structure of the gut microbiota in irradiated male medflies. We find that the sterilizing irradiation procedure affects the gut bacterial community structure of the Mediterranean fruit fly. Although the Enterobacteriaceae family remains the dominant bacterial group present in the gut, the levels of Klebsiella species decreases significantly in the days after sterilization. In addition, we detected substantial differences in some bacterial species between the mass rearing strain Vienna 8 and the wild strain. Most notable among these are the increased levels of the potentially pathogenic species Pseudomonas in the industrial strain. Testing the hypothesis that regenerating the original microbiota community could result in enhanced competitiveness of the sterile flies, we found that the addition of the bacterial species Klebsiella oxytoca to the postirradiation diet enables colonization of these bacteria in the gut while resulting in decreased levels of the Pseudomonas sp. Feeding on diets containing bacteria significantly improved sterile male performance in copulatory tests. Further studies will determine the feasibility of bacterial amelioration in SIT operations.
