Pests and Potential Problems
<br />Many species of insects and mites inhabit antelope
<br />bitterbrush, several of these are beneficial. It should
<br />be noted that bitterbrush is insect pollinated. Insects
<br />that cause problems include defoliators such as
<br />mountain mahogany loper and Western tussock moth.
<br />Some of the noted seed insects are bitterbrush seed
<br />midge, Say's stinkbug, dark bitterbrush leaf tier,
<br />white collared leaf tier, and flower thrips. Large
<br />numbers of seedlings and small plants have been
<br />destroyed by cutworms and false wireworms.
<br />Diseases associated with bitterbrush include root rot,
<br />root and stem wilt, and root-stem canker. Seedlings
<br />have been damaged by damping off (a disease caused
<br />by fungi).
<br />Environmental Concerns
<br />There are no known environmental concerns
<br />associated with antelope bitterbrush.
