State dependent problems for arthropods

Insects and other arthropods face a number of (non-cognitive) decisions while foraging for resources, including whether to accept a current site for exploitation, which resources …

Energy reserves modulate host acceptance decisions in mountain pine beetles

I tested the role of energy reserves on the host tree acceptance of mountain pine beetle (MPB) adults on host trees. Newly-emerged adult MPBs were kept at either high or low …

Mountain pine beetle condition and timing of emergence: who emerges when

Individual variation in energy reserves and timing of emergence are expected to constrain host selection decisions of mountain pine beetle. We examined the timing and condition of …

A dynamic host selection model for mountain pine beetle, Dendroctonus ponderosae Hopkins

The link between individual habitat selection decisions (i.e., mechanism) and the resulting population distributions of dispersing organisms (i.e., outcome) has been little-studied …

Mountain pine beetle condition and timing of emergence: who emerges when

An individual model of host selection for mountain pine beetle

Reproduction in mountain pine beetle (Dendroctonus ponderosae Hopkins) is contingent upon successful search for and attack of a suitable host tree (Pinus spp., especially lodgepole …

'I'll have the steak special, with a side salad': exploring the evolution of omnivory

Beetles pine for lodgepole homes: mountain pine beetle's search for a host

Reproduction in Mountain Pine Beetle (Dendroctonus ponderosae) is contingent upon successful search for and colonization of suitable host trees. Field data, collected from a 1.42 …

Using game theory to evaluate host acceptance decisions in mountain pine beetle

Mountain Pine Beetle, a native species of North American forests, searches out and colonizes live trees such as lodgepole pine. Female beetles have a limited period of time to find …
