The presence of SWD in northern Italy is in strong increase, after hitting the final production of cherry is now passing on strawberry and blueberry; high temperatures of recent days have slowed spawning but the danger is still high.
It is recommended maximum attention to the control of adults in crops, as an alternative to the capture of mass or mesh nets thin it proposes the method previously described : click here

Spotted Wing Drosophila - Update May 2015

Spotted wing Drosophila - control system

These days we are watching the first eggs laid on cherry fruits early maturing, the potential inoculum of adults is very high, and the females have already mature eggs. For a good defense we have to isolate the cultivation with fine nets, better every single row; or use where there is the possibility of ceiling fans (image) at the distance of 15-20 meters from each 'other and 2 meters above the vegetation. This method serves to disturb the flight of SWD and consequently the deposition of the eggs on the fruits. Last choice is the 'use of pesticides with more or less satisfactory results and with considerable risk to consumers.

Droshophila Suzuli and grapes

With reference to a recent report by Nicola Mori - University of Padua held in S. Michele a / Adige on 09.01.2015 on the issue of damages by SWD in the fruit drying of grapes to produce wine Recioto Amarone etc. we want to point out that the solution could be nell'intallazione of ventilatoriin verticale.invece that horizontal position; this is because the SWD is very disturbed by the movement of air.

Drosophila Suzukii control

• How do you save the production .....One day a friend organic producer called me on the phone and asks me what I can do to save his strawberry production re-bloom from SWD , then I asked him how serious the damage and he replies pretty serious . At this point I ask him again if he has the chance to have electricity in the camp and he replies that can use the energy of the PV system . Without a moment's hesitation I propose to install the agitators of air above the rows of strawberry plants, said and done after a few days you could see a marked improvement in the appearance of the fruit , and after 8-10 days the problem had disappeared and the production at a distance of two months is still good and without having used insecticides of any kind.See you next good story.

SWD-Drosophila Suzukii update august 2013

Excellent results were obtained with the method of air agitators on strawberry. The plants subjected to treatment have not suffered damage and continue to produce normally.
The pressure of the flight of SWD is at its maximum and the crops most at risk are raspberry, strawberry and grapes.

Spotted Wing Drosophila - upgrading the 07 august/2013

The presence of SWD in the cultivation of small fruits is rapidly increasing especially in raspberry and blueberry in areas with microclimate favorevole.Si recommended to be very careful where there is poor ventilation, high humidity and shade of the forest.
The conditions unfavorable to the flight of SWD are: temperatures above 26 ° C, with low RH environments, the presence of wind, continuous rainfall.
Remedy for organic and biodynamic farms: insect screens or application of air agitators ( image) to create a better ventilation in the critical moments of the day (morning and late afternoon).

Spotted Wing Drosophila - update July 2013

Quite worrying situation in the most favorable attack of Spotted Wing Drosophila, or areas with high average relative humidity poorly ventilated (image) especially in the morning and late in the afternoon.Nel case of strong presence of adults the techniques of mass trapping and insecticide treatments fail to contain the damage below the danger level. In these cases it can make recourse to means altenativi as the installation of air agitators installed above the cultivated plants, the density of these devices can vary according to the type of crop. In cultivation of full field is recommended a distance of about 20 meters from each other. The operating times may vary according to weather conditions, or in the presence of wind or rain or temperatures above 27 ° C (except protected crops) need not be put into operation, in contrast to these conditions is also required for the entire days.
