Monitoring spotted wing drosophila in Ventura County blueberries – June update

Aug 27, 2010

Today Ventura County Cooperative Extension Staff Research Associate Maren Mochizuki shares with us local SWD research results for the month of June.

For the month of June, we have detected an average of 1-2 individual spotted wing drosophila (SWD) per week (evenly split between males and females) at two of the three locations (Fig. 1).  SWD was trapped in raspberries adjacent to these two locations in mid-April.

Graphed data summarizing the trapping results is shown below. More information about local SWD research can be found here (make link to SWD local research posts)
