Collapse ▲This is the last blueberry monitoring report for 2017. All of the samples have been processed and the data updated and entered. There were large spikes in trap captures at all of sites that were still being monitored for target pest activity. This was not unexpected due to the precipitous decline in fruit availability over the last two weeks of trapping.
All moth traps were removed from all sites on June 6th because the activity period for these insects has concluded.

No blueberry maggot flies were found in any traps over the entire trapping period.
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, 59 SWD were captured at New Hanover 1, 139 SWD were captured at Bladen 3, 70 SWD were captured at Bladen 1, 31 SWD were captured at Bladen 4, and 9 SWD were captured at Sampson 1.
No cranberry fruitworm moths were captured during this trapping period
No cherry fruitworm moths were captured during this trapping period.
