Ecology of Mite Phoresy on Mountain Pine Beetles
… interaction and demands clarification. In bark beetles (Scolytinae), both effects are documented during reproduction and effects on hosts during the actual dispersal are largely unknown. In the present research, I investigated the ecological mechanisms that determine the net effects of the …

Mite and fungal associates on mountain pine beetles attacking three pines species in northern Colorado
During its life cycle, mountain pine beetle (Dendroctonus ponderosae) interacts with phoretic organisms such as mites, nematodes, fungi, and bacteria. The types of associations these organisms establish with the mountain pine beetle vary from mutualistic to antagonistic. The most studied of these …

Biophysical and Climate Analysis of the Mountain Pine Beetle (Dendroctonus ponderosae) Infestations in the Crown of the Continent, 1962 to 2014
Mountain pine beetles (Dendroctonus ponderosae) are native insects that have decimated millions of hectares of mature pine (Pinaceae) forests in western North America. The purpose of this study is to investigate biophysical and climatic correlates of Mountain Pine Beetle (MPB) insect outbreaks in …

The Southern pine beetle, Dendroctonus frontalis Zimm., and associated Coleoptera attracted to dead loblolly pine, Pinus taeda L.
This study tests the hypothesis: Bark beetles initially locate their host trees in a non-random manner. The association of the southern pine beetle (<u>Dendroctonus frontalis</u> Zimm.) and associated Coleoptera with stressed trees suggested the direction for this study. Loblolly pine trees, …

Restoration planting options for Pinus flexilis James in the southern Rocky Mountains
… threatened by the combined impacts of mountain pine beetles and white pine blister rust. P. flexilis' critical role in high elevation ecosystems heightens the importance of mitigating threats to P. flexilis survival. To develop forest-scale planting methods, six P. flexilis seedling planting …

Mountain Pine Beetle Detection using IoT
… evaluate an IoT system for real-time Mountain Pine Beetle (MPB) infestation detection using bioacoustic recognition via deep learning techniques. First, we present the design of the IoT system and describe its various hardware and software components. We built our IoT device using LoRa …
