Rules
I. This contest shall consist of two parts: an objective type examination on 24 insects of California and oral presentations of two insects and one vertebrate pest.
II. The pest will be displayed in the most appropriate mount available. As many growth stages of the insect will be shown as is possible, including at least the stage most commonly seen in nature.
III. Only common names will be used in the contest and must be used as listed in the Code to receive credit. Scientific names are included only as an aid to help in identification study prior to the contest.
IV. Objective Type Examination
A. The time allowed shall be 24 minutes for identification on a rotation basis and six minutes for a recheck of specimens and answers.
B. Misspelling the common name of any insect or pest will result in the deduction of ten points per specimen name misspelled. No deduction for capitalization error.
C. Contestants must check the appropriate places on the contest form for all destructive stages of the pest; if the contestant lists only half of the destructive stages for a particular pest, he/she will receive only half the points allowed in that part of the form. Mouth parts of the most destructive stage will be indicated by the contestant. If an insect does not have a nymphal or larval stage, the word "young" would be synonymous for nymph.
D. Contestant must FILL IN the scientific order of each pest in the identification section of the contest. Misspelling of the scientific name will result in a ten point deduction per name misspelled.
E. Only the entire common name as listed in the Curricular Activities Code will be scored as correct.
F. The following is an example of the type of form that will be used.
