Table 1.

The sum of average monthly Fahrenheit (F) temperatures for December 2002, January and February 2003 is used to predict flea beetle survival in Missouri. High and low Fahrenheit temperatures were obtained by the University of Missouri Commercial Agriculture Automated Weather Station Network from the Agricultural Electronic Bulletin Board (AgEBB).

If the sum of average Fahrenheit temperatures for December, January and February is: lower than 90° F, low flea beetle survival is indicated, between 90°F and 100°F moderate or variable flea beetle survival is indicated, or higher than 100° F, good flea beetle survival is expected. Temperatures did vary within listed regions. Look at the station(s) near you for further hints on flea beetle survival.
