DROPSA newsletter - final issue

Dropsa EU project comes to a close Feb 2018

At the annual International Soft Fruit Conference (ISFC) in Den Bosch (The Netherlands), the European members of the Dropsa project presented their findings to stakeholders. In total 760 people from 32 nationalities, 20 presenters and 98 companies from 13 countries were present at the ISFC.

The EU funded project "DROPSA" aims were to develop effective, innovative, practical and integrated solutions for the control of pests and diseases. During the four-year project, Fera and 25 partners throughout Europe, Asia, New Zealand and North America have examined several potential chemical, biological, cultural, integrated and novel pest and disease control strategies.

Strategies to develop effective, innovative and practical approaches to protect major European fruit crops from pests and pathogens

Drosophila suzukii and quarantine pathogens such as Pseudomonas syringae pv. actinidiae (Psa), Xanthomonas fragariae (Xf) and X. arboricola pv. pruni (Xap) that have been introduced into Europe are posing major challenges to fruit production and are causing substantial economic losses. Read more

Integrated pest management of Drosophila suzukii

The invasive spotted wing drosophila, Drosophila suzukii, is particularly difficult to manage in Europe. It has a very wide host range including fruits from many ornamental and wild plants and a short generation time, which allows the development of several generations per year. Read more

Biological control of Drosophila suzukii using natural enemies from Asia

Following surveys in China and Japan, DROPSA partners are now evaluating the suitability of Asian parasitoids for the biological control of D. suzukii in Europe. The most promising candidate is a small wasp of the family Figitidae, provisionally identified as Ganaspis brasiliensis (but the taxonomy of the Ganaspis genus is under revision). Read more

Spotless strawberry plants: how to keep them free from Xanthomonas?

Xanthomonas fragariae (Xfr) is the causative agent of angular leaf spot of strawberry, a quarantine organism in Europe in plant propagation material (EPPO A2). Protected cultivation of strawberry plants in general resuIts in a pathogen free crop. However, if plants are grown in the field, infections occasionally occur which can result in high economic damage. Read more

Managing pathways of pest and disease introduction

A pathway is defined as any means that allows the entry or spread of a pest (FAO, 1990). Trade in food commodities is an important means by which pests and diseases are introduced to new regions and countries. Analysis of genetic markers in the Spotted winged drosophila (Drosophila suzukii) show that it was introduced by trade into Europe on at least two separate occasions. Read more

Use of toxic baits for the control of Drosopila suzukii

A toxic bait is "a food containing a poison". The food improves the uptake of the poison by the insect, in order to improve the efficacy of the insecticide. As adult D. suzukii actively search sugars and proteins on the plants’ surface, the species is a candidate for control with baits. But in field experiments, the use of baits against SWD has given variable results so far. Read more

Comparison of traps and attractants for Drosophila suzukii monitoring in North-East Italy

A prompt and wide-area monitoring of D. suzukii is the pre-requisite to set up a rational and effective control strategy.
Different types of traps and lures based on food attractants have been developed; the aim of these surveys carried out in 2014, 2015, 2016 and 2017 in Modena, Trento and Verona districts was to test the activity of different combinations commercially available. Read more

Posters presented at final Dropsa meeting January 2018

At the final meeting in January 2018 posters were presented on the aims of the project, possible pests imported with fruit to Europe, Drosophila suzukii control and a Decision Support System, management plans for kiwi crops against PSA and a diagnostic tool for improved detection of Xf. Read more

Le avversita' del Kiwi

Dr. Francesco Spinelli (Department of Agricultural and Food Sciences - University of Bologna) organized a final PSA-presentation during the kiwifruit day by the Italian Society for Horticultural Sciences (1st February 2018). Read more

Newsletter March 2017

In 2017 DROPSA has entered its fourth and final year and is making substantial progress in its aims and objectives towards the development of reliable, robust and cost-effective approaches to protect the major European fruit crops from Drosophila suzukii and the bacterial pathogens Pseudomona syringae pv. actinidiae, Xanthomonas fragariae and X. arboricola pv. pruni.
