Spotted Wing Drosophila suspect crop damage.

Hueppelsheuser notes there are initiatives in B.C. to survey for the Asian bio-control agent, a tiny wasp which lays its eggs in stink bug eggs. This tiny beneficial wasp will help limit the populations of the stink bug. Research results in the USA show that this wasp prefers BMSB eggs, which is very promising, she adds. SPOTTEDWINGDROSOPHILA In the Okanagan, there are still small monitoring programs conducted by packinghouses but the ministry no longer is involved.
However, in the Fraser Valley, surveys for overwintering Spotted Wing Drosophila indicate there were many who overwintered, so ministry and industry officials are very concerned for berry crops this season.
Hueppelsheuser says survey results from traps in woods and hedgerows adjacent to berry fields indicate the tiny vinegar fly was active and present throughout winter and into spring. “There were only a handful of SWD- lethal days, so many of the flies survived winter this year,” she reports. A pest of thin-skinned fruit, it infests sound fruit, before it becomes over- ripe, unlike other fruit flies, so it can be devastating to commercial fruit crops if not controlled.
Females lay their eggs inside fruit, causing it to become soft and unmarketable.
Looking Back J
. H. E ‘Huddy’ Hudson was one of the Okanagan’s earliest photographers. He arrived in the Valley shortly after 1900 and remained for roughly 10 years, and over that time he was prolific in recording a wide array of images that remain as part of the region’s vital historical record. From streetscapes and landscapes to construction sites and panoramas, Hudson’s iconic photographs delight the viewer and inform the historical record.
Several of Hudson’s photos were turned into postcards in the pre-World War I era, and many of the region’s museums and archives have copies of the postcards that were sent worldwide and helped advertise the Valley. This photo, taken in Penticton, is typical of that era.
Hudson opened his business in Kelowna first but eventually he had a studio in Penticton as well. With two sites, he was well positioned to capture the region’s burgeoning tree fruit industry.
Perhaps most iconic of his work were the panorama scenes that capture something of the dimensions of the landscape change under way. Between
1904 and 1914 tens of thousands of acres of grazing land, grain fields and hay flats were converted to the manicured and
symmetric rows of orchard in the Okanagan Valley — and Hudson’s work helps show the magnitude of that shift as the Valley turned from brown to green.
This postcard image was taken in Penticton looking north up Okanagan Lake toward Summerland. The mountain in the distance on the left is Giant’s Head. The postcard itself is titled, ‘A three year old’, is clearly pioneer orcharding humour at its finest. I seem to recall Randy Manual, former executive director of the Penticton Museum, telling me that the little girl was actually his grandmother. If you have photos or artefacts of our rich agricultural heritage, please contact the B. C. Orchard Industry Museum at 778-478-0347.
