Make the table in Microsoft Word. Use Times

#
in the email message subject. Please check with a virus protect
program before emailing. Email to
pests@umn.edu.

For #2, please specify which life
stage corresponds with your degree days (egg hatch, 2nd instar, adult
emergence, etc.). See links below for details.

Using the information from your table,
develop an IPM program for each pest. (5 pts total, or about 0.8 pts
per pest) This IPM program should be a
