Charts

Insect models show the predicted pest development (e.g. egg hatch, adult emergence, or proportion of instars) over degree-days or time. The chart can be displayed in 4 different ways:

  • relative number vs. degree-day accumulation

  • percentage of development vs. degree-day accumulation

  • relative number vs. date

  • percentage of development vs. date

To change the chart, use the pull down menu located directly above.

Disease models show the calculated and predicted infection risk vs. date.

The chart for storage scald model shows the accumulated hours under 50°F vs. date.

Hovering over the graph with the cursor will show individual data points.
