On-Farm Research in Cranberry: SPARG Trap Design & Color

In 2012 we started a study to compare the efficacy of different trap designs (delta versus wing traps) and colors (white versus red) on Sparganothis fruitworm (SPARG) adult captures. We found that red delta traps (Trécé Pherocon VI) are more effective than white delta traps. White delta traps also catch greater number of honey bees, and it is possible that this saturates the sticky traps. We are continuing this work and testing this hypothesis in 2013. Results from these studies will be presented at future grower meetings.
