Flight polyphenisms naturally occur as discrete or continuous traits in insects. Discrete flight polyphenisms include winged and wingless morphs, whereas continuous flight polyphenisms can take the form of short- or long-distance fliers. The mountain pine beetle (Dendroctonus ponderosae) exhibits...

To date mountain pine beetle (MPB) has affected more than 19 million ha. of pine forests in Canada. The primary species affected by the current outbreak has been lodgepole pine (Pinus contorta), however as MPB range expands eastward beyond its historical habitat, the bark beetle has encountered a...

Dispersal by flight is a complex life history phase in many insects that is essential to gene flow and range expansion. Many elements contribute to realized dispersal, including biotic and abiotic environmental conditions, as well as intrinsic factors such as morphology, physiology and behavior....

The pea leaf weevil, Sitona lineatus Linnaeus (Coleoptera: Curculionidae) is an invasive pest of increasing concern to pulse producers in the Canadian Prairie Provinces. Pea leaf weevil larvae cause damage to field pea (Pisum sativum) and faba bean (Vicia faba) crops by feeding on root nodules...

Irruptive forest insect pests cause considerable ecological and economic damage, and their outbreaks have been increasing in frequency and severity. We use a phylogeographic approach to understand the location and progression of an outbreak by the MPB (Dendroctonus ponderosae Hopkins), an...

In the last century the frequency and severity of outbreaks of tree-killing Dendroctonus beetles (Coleoptera: Curculionidae) have increased. Small-scale drivers within trees likely drive outbreak dynamics across landscapes. At a small scale, variation in carbohydrate availability within the stems...

Nutritional composition of plants can affect the performance of insect herbivores and their associated microbial symbionts. Mountain pine beetle (Dendroctonus ponderosae) is an important bark beetle species that colonizes many species of Pinus within its historical range and encounter host...

Planning forest management relies on predicting insect outbreaks such as mountain pine beetle, particularly in the intermediate‐term future, e.g., 5‐year. Machine‐learning algorithms are potential solutions to this challenging problem due to their many successes across a variety of prediction...
