Blueberry Insect Monitoring Report, 2 June 2017

— Written By Grant Palmer and last updated by

Despite the rainy weather last week being favorable for spotted wing drosophila, trap counts continue to drop.

No cranberry fruitworm moths or cherry fruitworm moths have been seen in our traps for weeks. Those traps will be taken down in the following week of scouting. We will continue monitoring for SWD, and blueberry maggot fly until the end of harvest.

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, 9 SWD were captured at New Hanover 1, 5 SWD were captured at Pender 1, 0 SWD were captured at Bladen 3, 0 SWD were captured at Bladen 1, 0 SWD were captured at Bladen 4, and 0 SWD were captured at Sampson 1.
