After the small surges in spotted wing drosophila trap captures at New Hanover 1 and Pender 1 the numbers appear to be dropping back down to levels similar to the other sites.

With the rainy weather throughout the last week we expect trap captures of SWD at all sites to show at least a small increase next week.

So far no blueberry maggot flies have been found at any of our trapping locations.

Six total blueberry fields are being monitored with five trapping stations at each field site and each station consisting of one spotted wing drosophila (SWD) trap baited with a yeast sugar-water mixture, one white “wing” sticky trap baited with a pheromone lure attractive to male cranberry fruitworm moths, one white “wing” trap baited with a pheromone lure attractive to male cherry fruitworm moths, and one yellow sticky trap baited with ammonium bicarbonate to attract blueberry maggot flies.

The average number of the total pests captured per site per day are presented in the figures below. YSW refers to traps baited with “yeast/sugar water.” SWD refers to “spotted wing drosophila.”

During this trapping period, 19 SWD were captured at New Hanover 1, 3 SWD were captured at Pender 1, 0 SWD were captured at Bladen 3, 1 SWD was captured at Bladen 1, 0 SWD were captured at Bladen 4, and 5 SWD were captured at Sampson 1.
