New research on the SIT method to combat Drosophila suzukii advances

Crop protection

07 Jan 2025

A genetics company and Oregon State University have released sterile males of Drosophila suzukii that have been genetically modified not to reproduce. The idea is that they will one day mate by laying non-viable eggs, thus causing the pest's population to collapse.

Leptopilin japonica: a valuable resource in the fight against Drosophila suzukii

Crop protection

02 Jan 2025

Leptopilina japonica joins Ganaspis brasiliensis in the Fondazione Edmund Mach trial. Although Ganaspis brasiliensis remains the leading candidate, it is expected that the two insects can work synergistically to enhance control efficacy.

The impact of root rot on sweet cherry tree metabolism and microbiome

Crop protection

31 Dec 2024

A study analyzed the effects of root rot on plant metabolism, soil physicochemical properties, and the composition of the root and rhizosphere microbiome. The results demonstrate that root rot is not merely an isolated disease but a condition that disrupts the entire system.

D.suzukii management in Emilia-Romagna on cherry trees: monitoring and Integrated Production strategies

Crop protection

20 Dec 2024

The Consorzio Fitosanitario di Modena is particularly engaged in various specialized research activities in favor of cherry producers. Among those, the one related to the annual monitoring of D. suzukii is considered one of the most important to guide technical consultants.

Genetics as starting point against Drosophila suzukii

Crop protection

18 Dec 2024

Researchers from the Ecological Sciences Division of the James Hutton Institute researched collecting infested fruit from both cultivated fields and natural areas to assess genetic differences between Drosophila suzukii individuals feeding on the various fruit cohorts.

Ganaspis kimorum: the Netherlands is studying how to integrate it to combat Drosophila suzukii

Crop protection

16 Dec 2024

Before the wasp can be introduced in the Netherlands, much remains to be done. Herman Helsen: ‘We have to prove that the introduction of the parasitic wasp will not disrupt the entire native fauna. A dossier is required for this authorisation'.

Bacterial canker: symptoms, causes, and prevention in the sweet cherry tree during the fall season

Crop protection

11 Dec 2024

The most evident symptoms of bacterial canker in sweet cherry are a dark canker, often accompanied by gummosis. Symptoms commonly develop at the base of trees, particularly in younger trees, which are more susceptible to damage caused by machinery, rodents, frost, and irrigation.

Exposure to low doses of insecticides in Drosophila suzukii: are there sublethal and chronic effects?

Crop protection

26 Nov 2024

A recent study from Poland analyzed the effects of sublethal doses of acetamiprid and nicotine on Drosophila suzukii, evaluating alterations in wing symmetry among exposed insects. The parameter used for evaluation was the "fluctuating asymmetry".

$325,000 grant for a revolutionary biopesticide against Drosophila suzukii

Crop protection

18 Nov 2024

Michigan State University aim to create a yeast-based biopesticide modeled after approaches proven effective against other species of flies and mosquitoes. The product works by disrupting the protein translation of the pests' ribonucleic acid (RNA).

Fighting Drosophila suzukii with sage essential oil

Crop protection

14 Nov 2024

Sage essential oil is known to repel a variety of agricultural pests but the effect on D. suzukii remains uncertain. In this chinese study researchers implemented behavioural essays to investigate the repellent properties of sage oil on larvae and adults of D. suzukii.
