Drosophila suzukii and wine grapes: host suitability and other possible impacts

Drosophila suzukii is a global pest attacking various berry crops. D. suzukii lays eggs in damaged as well as in intact wine grape berries of the most soft-skinned varieties. Here we describe the relative host suitability of different wine grape cultivars (international and local), compared to other berry crops. Assessment has been performed both in the field and in the laboratory and results were correlated to the change in the surface penetration force and harvest time of the tested varieties. D. suzukii flies can be found feeding on damaged wine grapes during the harvest period, especially when the skins of berries are impacted by cracking, disease and bird damage. From the results of the present study, it is inconclusive that D. suzukii is a vector of Acetobacteria in wine grapes during the latter portion of the season. Further investigation of the interactions between D. suzukii and Acetobacteria would be necessary to determine whether increased levels of Acetobacteria due to D. suzukii activity levels will impact production cost and quality of high-value wine

Statistical Fault Injection: Quantified Error and Confidence

ISBN:978-3-9810801-5-5International audienceFault injection has become a very classical method to determine the dependability of an integrated system with respect to soft errors. Due to the huge number of possible error configurations in complex circuits, a random selection of a subset of potential errors is usual in practical experiments. The main limitation of such a selection is the confidence in the outcomes that is never quantified in the articles. This paper proposes an approach to quantify both the error on the presented results and the confidence on the presented interval. The computation of the required number of faults to inject in order to achieve a given confidence and error interval is also discussed. Experimental results are shown and fully support the presented approach

Efficacy of insecticide treatment strategies against Drosophila suzukii in combination with mass trapping

A field trial of integrated management against D. suzukii was carried out in a blueberry orchard in Trentino region. Mass trapping with red traps containing an attractive based on apple vinegar and wine (Droskidrink) was used for the entire experimental site. Treatments were: Spada 200 EC, Laser and Boundary. Assessments were made on fruits picked every 3-7 days during all the harvest time. The insects caught in the traps were also weekly counted. The damage observed on the three treatments was always similar and low during all the harvest time, reaching high values only in the last assessment, at the end of harvesting (90% of production already harvested). A semi-field trial was carried out to verify whether the 3 protection strategies were really equally effective. Fruits were collected 7 days after the last insecticide application and kept in contact for 24 hours with D. suzukii adults reared in the laboratory. At the end of this period, oviposition and the development of adults was verified. The oviposition was not significantly different between treatments, even if the Boundary treated fruits showed a presence about twice of eggs compared with the insecticides (Spada 200 EC, Laser). The number of emerged adults showed evident differences between treatments. Spada 200 EC was the most effective, showing a lower developmental rate of adults, while Boundary was the less effective. Laser showed an intermediate efficacy. The three strategies showed a different efficacy in the semi-field trial and were similar in the field. These results could be explained with the presence of mass trapping in the orchard, which covered the differences between treatments emerged in the semi-field experiment. The arrangement of mass traps, carried out on the perimeter of a plot of limited area, has certainly enhanced their effectiveness. The efficacy demonstrated by this technique requires to consider it as a valuable tool in the management of D. suzukii on blueberr

Precisely Controlling the Duration of Fault Injection Campaigns: a Statistical View

ISBN:978-1-4244-4321-5International audienceFault injection has become the main approach to evaluate the dependability of a circuit with respect to soft errors. It can be applied early during the design process and refined along all design steps. However, the main limitation is the huge number of faults that should be injected when large circuits and/or complex workloads and complex error models are considered. This usually leads to practical campaigns based on a randomly selected subset of all potential faults. However, results obtained in these conditions are only estimations and the error on the estimation is never quantified in the literature. This paper presents an approach to quantify both the error on the presented results and the confidence on the computed error interval. Conversely, the computation of the required number of faults to inject in order to achieve a given confidence and error interval is also discussed. Experimental results are shown, fully supporting the presented approach
