Box 100, A-1400 Vienna, Austria 4Entomology Unit, FAO/IAEA Agriculture and Biotechnology Laboratory, Seibersdorf, Austria Fruit flies are the main constraint to improving production and trade of fruits and vegetables in Thailand. Therefore, since 1987, the Department of Agricultural Extension (DOAE) in cooperation with the Office of Atomic Energy for Peace has run a pilot project for control of the oriental fruit fly (OFF),Bactrocera dorsalis (Hendel),by integrating the sterile insect technique (SIT) with other moni- toring and control methods in the mango-production areas in the Paktor District in the Ratchaburi province. The project includes mass-rearing and sterilization of OFF at the mass-rearing and steril- ization facility of the Irradiation for Agricultural Development Institute, DOAE, located in the Pathumthani Province and field releases of sterile flies complemented by bait sprays and a monitor- ing network of methyl eugenol baited traps. The International Atomic Energy Agency has pro- vided technical assistance since 1991 through a Technical Cooperation Project. The assistance has resulted in improved rearing and field operation activities. In the years 1999 and 2000, weekly ground shipments of 5–10 million sterile pupae were transported from the production facility in Pathumthani to Paktor District for ground release in 1120 ha of small commercial mango orchards. -
Gamma Radiation Sterilization of Bactrocera Invadens (Diptera: Tephritidae) from Southern Ghana

Accepted 1 June, 2012 The African invader fly, Bactrocera invadens, an invasive pest in Africa since 2003, causes damage and poses a threat to the mango and horticultural industry. Its control is therefore needed. Sterilization of males using gamma radiation doses (25, 50 and 75 Gy) as a means of population control was investigated. Irradiation at the pupal stage (about 6 days after pupation) was found to be suitable. It was observed that a gamma radiation dose of 75 Gy rendered males of B. invadens completely sterile, while doses of 25 and 50 Gy induced partial sterility in the males. Females were made completely sterile by all doses of radiation tested. Key words: Bactrocera invadens, mango, gamma radiation doses, Sterile Insect Technique, fertility. INTRODUCTION In 2003, the African invader fly, Bactrocera invadens Furthermore, the presence of B. invadens in sub-Sahara (originating from Asia) was detected in Kenya and was Africa hampers trade between this region and other reported to be spreading across tropical Africa (Lux et al., regions of the world (Guichard, 2008, 2009). -

Yuval: [email protected] Abstract. Philornis downsi (Diptera: Muscidae) is a nest parasitic fly that has invaded the Galapagos archipelago and exerts an onerous burden on populations of endemic land birds. As part of an ongoing effort to develop tools for the integrated management of this fly, our objective was to determine its long and short-range responses to bacterial and yeast cues associated with adult P. downsi. We hypothesized that the bacterial and yeast communities will elicit attraction at distance through volatiles, and appetitive responses upon contact. Accordingly, we amplified bacteria from guts of adult field-caught individuals and bird feces, and yeasts from fermenting papaya juice (a known attractant of P. downsi), on selective growth media, and assayed the response of flies to these microbes or their exudates. -
Can Darwin's Finches and Their Native Ectoparasites Survive the Control of Th
Insect Conservation and Diversity (2017) 10, 193–199 doi: 10.1111/icad.12219 FORUM & POLICY Coextinction dilemma in the Galapagos Islands: Can Darwin’s finches and their native ectoparasites survive the control of the introduced fly Philornis downsi? 1 2 MARIANA BULGARELLA and RICARDO L. PALMA 1School of Biological Sciences, Victoria University of Wellington, Wellington, New Zealand and 2Museum of New Zealand Te Papa Tongarewa, Wellington, New Zealand Abstract. 1. The survival of parasites is threatened directly by environmental alter- ation and indirectly by all the threats acting upon their hosts, facing coextinction. 2. The fate of Darwin’s finches and their native ectoparasites in the Galapagos Islands is uncertain because of an introduced avian parasitic fly, Philornis downsi, which could potentially drive them to extinction. 3. We documented all known native ectoparasites of Darwin’s finches. Thir- teen species have been found: nine feather mites, three feather lice and one nest mite. No ticks or fleas have been recorded from them yet. 4. Management options being considered to control P. downsi include the use of the insecticide permethrin in bird nests which would not only kill the invasive fly larvae but the birds’ native ectoparasites too. 5. Parasites should be targeted for conservation in a manner equal to that of their hosts. We recommend steps to consider if permethrin-treated cotton sta- tions are to be deployed in the Galapagos archipelago to manage P. downsi. Key words. Chewing lice, coextinction, Darwin’s finches, dilemma, ectoparasites, feather mites, Galapagos Islands, permethrin, Philornis downsi. Introduction species have closely associated species which are also endangered (Dunn et al., 2009). -

In two different farming scales, small and large, we verified the influence of suppressing the invasive Bactrocera dorsalis using the male specific attractant, methyl eugenol (ME), formulated in SPLAT-spinosad. In small-scale farm plots, use of ME did reduce B. dorsalis populations, but population levels remained high throughout the study. In mark-release-recapture studies, male flies were found to disperse fast and beyond one km from the release point. In large-scale farm plots, the invasive pest was controlled within eight months of suppression using ME-based suppression in combination with other pest management techniques. However, this was paralleled by a quick resurgence of the native fruit fly Ceratitis capitata, likely due to competition release. -

Involvement of the Antennal and Maxillary Palp Structures in Detection and Response to Methyl Eugenol by Male Bactrocera Dorsalis (Diptera: Tephritidae)

The discovery of methyl eugenol (ME) as a potent male attractant for this species has led to its successful use in area-wide fruit fly control programs such as male annihilation. While the antenna is recognized as primarily responsible for male flies’ detection of attractants such as ME, little is known of the involvement of the maxillary palp. Using behavioral assays involving males with intact and ablated antennae and maxillary palp structures, we seek to ascertain the relative involvement of the maxillary palp in the ability of the male fly to detect ME. In cage bioassays (distance of ≤40 cm from the source), >97% of unmodified males will normally show a response to ME. Here, we showed that 17.6% of males with their antennae ablated were still attracted to ME versus 75.0% of males with their palps ablated. -

Simple Summary: Tephritid fruit flies comprise pests of high agricultural relevance and species that have emerged as global invaders. Chemical signals play key roles in multiple steps of a fruit fly’s life. The production and detection of chemical cues are critical in many behavioural interactions of tephritids, such as finding mating partners and hosts for oviposition. The characterisation of the molecules involved in these behaviours sheds light on understanding the biology and ecology of fruit flies and in addition provides a solid base for developing novel species-specific pest control tools by exploiting and/or interfering with chemical perception. Here we provide a comprehensive Citation: Scolari, F.; Valerio, F.; overview of the extensive literature on different types of chemical cues emitted by tephritids, with Benelli, G.; Papadopoulos, N.T.; a focus on the most relevant fruit fly pest species. -

Both Philornis downsi natural fluctuations in environmental conditions and habitat management measures can temporarily cause Darwin's finches adverse environmental effects. In this study, we investigated the interaction between the invasive parasitic fly Invasive species Philornis downsi, control of invasive plants and precipitation on the breeding success of Darwin's finches. Parasitism Introduced plant species have invaded a unique forest on the Galapagos island of Santa Cruz, which is a key Arthropod biomass habitat for Darwin's finches. The Galapagos National Park Directorate applies manual control and herbicides to Weed management combat this invasion. We hypothesized that these measures led to a reduction in the arthropod food supply during chick rearing, which in turn caused mortality in chicks that were already weakened by parasitism. We compared food availability in three study sites of varying degrees of weed management. To assess the interaction of parasitism and weed management, we experimentally reduced P.
