Tests for Galerucella calmariensis

No-choice tests: A no-choice test is when the potential biological control agent is placed into a cage in which only the test plants are present. The insect must either feed on the plants or starve. Starvation tests are used to determine whether or not an insect is safe to bring into the country and release as a biological control agent. The outcome of these tests are quite different from the outcomes seen in preference tests where the insect in question is given a choice between the target plant and the test plants.

Original no-choice tests: To obtain permission for importation and release in the United States, tests were made using three categories; 26 species of taxonomically related plants, 15 species of associated wild plants of wildlife importance, and 7 species of important agricultural plants.

In the following table an x is positive for feeding by adults or larvae, and egg laying. An (x) is positive but limited and not considered significant. Common names followed by the letter M indicate that the data was taken from: The Purple Loosestrife Project at Michigan State University (Progress Report) 13 pages, by Doug Landis and Mike Klepinger, 21 August 1998.
