Deselect Fruits Version

The charts are updated daily and show the number of SWD vinegar flies recovered from monitoring traps.

Each crop is represented by a different color and/or symbol.

The table beneath the chart indicates SWDs found to date and how many trap-sites are located in that quadrant for that crop.

There are many mitigating factors, such as pesticide applications, that can affect these trap counts. So please use them only as an overall indicator of the presence or absence and overall size of the insect’s population levels.
