Locations and Data

How to use this map

Click any of the markers, which represent locations of aphid traps, to see information on how many immigrating winged aphids were trapped at that location on each date throughout the season. The data are updated as soon as they are obtained. If aphids are found to be carrying viruses on any date, that will be noted. Maps for the current year will be posted as soon as data can be acquired and analyzed.
