Blueberry Insect Monitoring Report, 19 May 2017

— Written By Grant Palmer and last updated by

There were small spikes in spotted wing drosophila trap captures at Pender 1 and New Hanover 1. New Hanover 1 is located at the Ideal Track blueberry research farm of the Horticultural Crops Research Station in Castle Hayne, and most traps are located in plots that are not treated with insecticide. Local vegetation and food resources also differs between sites all our sure.

New cranberry fruitworm and cherry fruitworm lures were put out at all locations last week. With only one cranberry fruitworm moth and no cherry fruitworm moths being captured between then and now, it seems that flights of these moths are coming to an end.

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, 29 SWD were captured at New Hanover 1, 15 SWD were captured at Pender 1, 0 SWD were captured at Bladen 3, 0 SWD were captured at Bladen 1, 1 SWD was captured at Bladen 4, and 1 SWD was captured at Sampson 1.
