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).

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.

Cross-species SIT technique: a new frontier for controlling Drosophila suzukii

Crop protection

13 Nov 2024

A recent Italian study analyzed the use of cross-species SIT, which leverages reproductive interference between different species to enhance effectiveness. The goal was to combat Drosophila suzukii, a pest that poses a threat to fleshy fruits such as cherries.

Pathogenicity tests showed that all isolated species could cause fruit infections, though with varying levels of aggressiveness. Among them, Diaporthe eres displayed the highest virulence followed by Fusarium incarnatum and Botryosphaeria dothidea.

Compatibility between chemical insecticides and nematodes against Drosophila

Crop protection

07 Nov 2024

Drosophila suzukii can be controlled either by chemical insecticides or by the use of entomopathogenic nematodes, which are easy to apply because they can be mixed in tanks together with other plant protection products, fertilisers and soil conditioners.

Biotechnological innovations in the control of Drosophila suzukii: techniques and perspectives

Crop protection

05 Nov 2024

Traditional management methods fail to fully control Drosophila suzukii. New innovative strategies are being developed and adopted, including the 'sterile insect technique', 'X-shredding' and the 'transgenic sexing strains' technique.
