Spotted Wing Drosophila (SWD)

(Question)

I have an  infestation of SWD. Can you please advise:

1.if soft fruit that is infected with larvae can be eaten after treated with salt water soak

2.how best to keep population down without using pesticides

 

(Answer)

 

Spotted Wing Drosophila is an invasive pest of berry crops. OMAFRA reports that they lay eggs in fruit as the fruit is ripening. Fruit loses it’s integrity and breaks down.  Fruit dropped off the plant can increase the population. To keep the population down it is important to harvest fruit daily. It is hard to say how long you would have to soak the fruit in salt water to make it edible and even after soaking the larvae would remain in the fruit. Very unpalatable.
