Pest Update - Potato Leafhopper

Tuesday, August 1, 2017

Potato leafhopper was first found in the Annapolis Valley in early July by Erika Bent (APM Agricultural Pest Monitoring Consulting Ltd.).  Both adults and nymphs are being found throughout Kings and Annapolis Counties on strawberry plants and tree fruits.  This insect does not over winter here, but arrives on wind currents.  Potato leafhopper feed on the leaves which results in a yellowing and crinkled appearance (see image below from Ontario CropIPM).  In addition, potato leafhopper is able to transmit aster yellows and green petal.

For additional information on identification and management of potato leafhopper in strawberries check out Ontario CropIPM - Potato Leafhopper and Perennia's Strawberry Management Schedule.

Note - We haven't found it on raspberries yet, but can also be a problem.

Spotted Wing Drosophila Update #1

Saturday, July 15, 2017

The first spotted wing Drosophila fly was found this past week in Kings County by Erika Bent (APM Agricultural Pest Monitoring Cons. Ltd.).  The female was found in a trap located in a hedgerow next to a commercial berry field.  This is a very early capture date and if you are planning on trapping for SWD on your farm traps should go out this week.  

Flies damage fruit by laying eggs in ripening fruit. The larvae quickly develop and feed on the inside of the fruit. Once this happens, it decreases harvestable yield and destroys the marketability of the fruit.  It can cause significant damage on a wide range of soft fruit, including: wild blueberry, highbush blueberry, strawberry (Day neutral and June bearing), raspberry, blackberry, cherries, peaches, plums, gooseberries, currants, grapes and a wide variety of wild and native fruits.
