Contest Events:
4. Insect & Disease Identification

Contestants will be asked to identify forest insects and disease specimens, or samples of their symptoms or signs. Samples may include bark showing characteristics bark beetle tunnels, pitch tubes, egg masses or other distinctive insect and disease signs. All specimens will come from the Official List of Insects and Diseases for Juniors OR Seniors as appropriate. The list has 10 forest diseases and 15 forest insects. The Senior list includes those on the Junior list plus additional species for a total of 21 diseases and 30 insects.

For the contest, approximately five insects and five diseases will be selected from the official list. As with tree identification, judging is based on accuracy of identification and correct spelling of complete common names. Incomplete or misspelled, but identifiable common names will receive partial credit.

The following insect and disease list is to be used for the 4-H Forestry Field Day Contests. It is arranged alphabetically by common names. Only the common names listed below are accepted in the contest. Capitalization of common names is not required.
