Nitrogen Assimilation & Fractionation in Mountain Pine Beetle & Its Associated Fungi: a Hypothesis Regarding the Onset of Beetle Outbreaks Grant uri icon



  • Bark beetles are the most serious insect pests of conifers throughout North America. The hypothesis to be tested is that tree nutrition affects beetle assimilation of nitrogen, thereby affecting reproductive success of the beetles and contributing to population increases and subsequent outbreaks. We will examine mountain pine beetle and its associated fungi in Idaho as our test system.
