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.

Spotted Wing Drosophila info

Dear readers, with great satisfaction the announcement goal of a thousand pages on this blog; the topic of interest is rather special and specific as (SWD) it is clear that concerns the world of research and the fruit sector.
This is a modest small contribution as opposed to the chemical solution distributed in the vicinity or even during the collection phase.
Very often scientific institutions ignore the solutions that are too trivial or simple though very effective, but for this I appeal to Entomologists not only consider the molecules as a panacea for the crops.
I wish you all good work and better results.







Cari lettori, con grande soddisfazione annuncio il traguardo di mille pagine su questo blog ; l' argomento di interesse abbastanza  particolare e specifico come (SWD) è chiaro che riguarda il mondo della ricerca e il settore frutticolo.
Questo è un modesto piccolo contributo in contrapposizione alla soluzione chimica distribuita in prossimità o addirittura durante la fase di raccolta.
Molto spesso le istituzioni scientifiche ignorano  le soluzioni troppo banali o semplici seppur molto efficaci, ma per questo faccio un appello agli Entomologi a non considerare solamente le molecole come panacea per le colture.
Auguro a tutti buon lavoro e sempre migliori risultati.
 

Spotted Wing Drosophila: alternative method for the control

Spotted wing Drosophila - control system

We are now at the beginning of the damage (SWD), here in northern Italy were found eggs on cherries fruits, raspberries and strawberries, next week we will also find on the blueberry. If someone is interested in saving production without using pesticides or networks can put  a shaker  air  (image) above the plants so as to disturb the flight of adults  (SWD), it can be programmed with a timer set to operate on two bands of the day most at risk and specifically in the morning and afternoon when there is no presence of wind. In the hottest hours of the day with temperatures> 27 ° C and the night is a risk of flight is very low.
The result of this system is fast enough, simply delete some of the fruits of the harvest next.
See here the results obtained: image

The distance between the devices varies depending on the speed of the blades, for example to the minimum speed the distance should not be above 18-20 meters, the average power consumption is 50 Watts / h.

The average cost of a device is $ 45-55.

Who is willing to try this system, I kindly ask you to communicate enentuali results obtained in the comments section or at the following contact: fruitculture@gmail.com

METODO ALTERNATIVO PER IL CONTROLLO DEL MOSCERINO DELLA FRUTTA -  DROSOPHILA SUZUKII

Se qualcuno è interessato a salvare la produzione senza l'utilizzo di pesticidi o reti può installare degli agitatori d'aria (vedi immagine) sopra le piante in modo da disturbare il volo degli adulti di D.S, tale metodo necessita di  collegamento alla rete elettrica e  può essere programmato tramite un timer impostato per operare nelle due fasce del giorno più a rischio per il volo degli adulti e in particolare al mattino e il tardo pomeriggio,in condizioni di scarsa presenza di vento. Nelle ore più calde della giornata con temperature > 27 ° C e alla notte il volo  è molto bassa.

L'effetto  di questo metodo è abbastanza veloce, è sufficiente eliminare parte dei frutti  dello stacco successivo.

Vedi qui i risultati ottenuti: image

La distanza tra i dispositivi varia a seconda della velocità delle pale, per esempio alla velocità minima la distanza non deve essere superiore a 18-20 metri, il consumo medio di un'unità è di 50 Watt / h.

Il costo medio di un dispositivo è di Euro 40-50.

Chi è intenzionato ad adottare  questo sistema di difesa è pregato gentilmente di comunicare gli eventuali risultati ottenuti  nella sezione commenti o al seguente contatto: fruitculture@gmail.com
