Shared senior authors and corresponding authors. y Received: 13 November 2019; Accepted: 10 December 2019; Published: 15 December 2019 Abstract: Sustainable pest control requires a systems approach, based on a thorough ecological understanding of an agro-ecosystem. Such fundamental understanding provides a basis for developing strategies to manipulate the pest’s behaviour, distribution, and population dynamics, to be employed for crop protection. This review focuses on the fundamental knowledge required for the development of an effective push-pull approach. Push-pull is a strategy to repel a pest from a crop, while attracting it toward an external location. It often relies on infochemicals (e.g., pheromones or allelochemicals) that are relevant in the ecology of the pest insect and can be exploited as lure or repellent. Importantly, responsiveness of insects to infochemicals is dependent on both the insect’s internal physiological state and external environmental conditions. This context-dependency reflects the integration of cues from different sensory modalities, the effect of mating and/or feeding status, as well as diurnal or seasonal rhythms. Furthermore, when the costs of responding to an infochemical outweigh the benefits, resistance can rapidly evolve. -

Rhagoletis Cerasi
OREGON DEPARTMENT OF AGRICULTURE FACT SHEETS AND PEST ALERTS Pest Alert: European cherry fruit fly Rhagoletis cerasi Introduction European cherry fruit fly (ECFF), Rhagoletis cerasi (Diptera, Tephritidae), is one of the most important cherry pests in Europe. In 2016, ECFF was found in Ontario, Canada. The following year it was found in the United States in New York state adjacent to the Canadian border. So far, ECFF infestations have only been found in Niagara County (Carroll and Herrmann 2017). ECFF is established throughout Europe to the Adult European cherry fruit fly female. Image by Claudia Daniel, Middle East. Research Institute of Organic Agriculture (FiBL). ECFF is a threat to cherries, one of Oregon’s top 20 Host Range agricultural commodities valued at over $70 million in All cherries are potential hosts. Honeysuckle berries 2017. Oregon is third in the nation in the production (Lonicera spp.) are also attacked, and there are records of sweet cherries. Home and organic cherry from snowberry (Symphoricarpos spp.). production are likely at the greatest risk. The primary risk of introduction for ECFF is in Pest Status infested fruit. This would include cherries, but also This is the most important pest of cherries in Europe. If honeysuckle and snowberries from the infested area in uncontrolled, they can destroy up to 100% of a cherry eastern North America or Europe. There are crop. Infested cherries are unmarketable. Control restrictions on the movement of fruits into the US, but techniques would be similar to those for the native it is unknown how the population arrived in the US in Western cherry fruit fly (WCFF), but there is evidence the first place. -

Abstract: Because of the successful application of hydrofoils on the America's Cup catamarans in the past two campaigns the interest in foiling sailing craft has boosted. Foils have been fitted to a large number of yachts with great success, ranging from dinghies to ocean racers. An interesting question is whether one of the slowest racing boats in the world, the Optimist dinghy, can foil, and if so, at what minimum wind speed. The present paper presents a comprehensive design campaign to answer the two questions. The campaign includes a newly developed Velocity Prediction Program (VPP) for foiling/non-foiling conditions, a wind tunnel test of sail aerodynamics, a towing tank test of hull hydrodynamics and a large number of numerical predictions of foil characteristics. An optimum foil configuration is developed and towing tank tested with satisfactory results. The final proof of the concept is a successful on the water test with stable foiling -

European Cherry Fruit Fly Rhagoletis Cerasi (Linnaeus) Lori R
Published by Utah State University Extension and Utah Plant Pest Diagnostic Laboratory ENT-201-18-PR October 2018 European Cherry Fruit Fly Rhagoletis cerasi (Linnaeus) Lori R. Spears, CAPS Coordinator, and Diane G. Alston, Extension Entomologist Quick Facts • European cherry fruit fly (ECFF) is a new invasive cherry-infesting pest from Europe. It was first detected in the U.S. in New York in 2017. It is not known to occur in Utah. • ECFF is a quarantine pest; its presence can restrict export markets for commercial fruit. • ECFF is closely related to and resembles western cherry fruit fly, the primary insect pest of sweet and tart cherries in Utah. • The major host plants are cherry and honeysuckle. Fig. 1. European cherry fruit fly adult. • Larvae of ECFF feed exclusively within fruits, causing them to rot and fall off the tree. In Europe, heavy infestations have resulted in 100 percent fruit loss. • Cultural controls include orchard sanitation and covering the soil under the tree canopy with ground cover, weed barrier fabric, or mulches. • Where it occurs, chemical control measures have been highly effective when properly timed and applied. uropean cherry fruit fly (ECFF,Rhagoletis cerasi Fig. 2. European cherry fruit fly adult. ELinnaeus) (Fig. 1) is a new invasive insect to North America. It naturally occurs throughout most of DESCRIPTION continental Europe and central and western Asia, and is Adults are about 1/8 to 3/16 inch long, slightly smaller the most economically important pest of sweet cherries than a house fly. The body is black with yellow markings in Europe. -

The tests involved treatments with an extract from the wood of Quassia amara (4 kg/ha) and an extract from the seeds of Azadirachta indica in the form of a ready-made formulation NeemAzal-T/S at a rate of 2.5 l/ha with the addition of a 0.3% sugar solution. A single treatment was performed in the first two years, and two treatments in the last year. The effectiveness of the protection of fruitlets against damage varied and for the Q. amara extract was from 8.3% (one treatment) to 86.1% (two treatments), and for the NeemAzal-T/S formulation from 4.8% (one treatment) to 44.3% (two treatments). In relation to the damage to fruits, the efficacy of the treatments also varied, ranging from 10.3% to 60% for the Q. amara extract, and from 0% to 46.7% for NeemAzal-T/S.

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.
