Major changes in gene expression between strains of diapausing and non-diapause spruce budworm despite little evidence of genetic divergence Open
To survive harsh winter conditions, many insects enter a state of dormancy called diapause which allows them to withstand extreme temperatures and lack of food. When diapause is induced, insects enter a state of arrested development and lo…

Tracking the North American Asian Longhorned Beetle Invasion With Genomics Open
Biological invasions pose significant threats to ecological and economic stability, with invasive pests like the Asian longhorned beetle ( Anoplophora glabripennis Motschulsky, ALB) causing substantial damage to forest ecosystems. Effectiv…

Plasticity in cryoprotectant synthesis involves coordinated shunting away from pyruvate production Open
Insects living in temperate regions often accumulate a large amount of glycerol during winter to avoid freezing. This seasonal accrual of glycerol is generally produced from glycogen reserves through the pentose phosphate pathway. An alter…

The freeze-avoiding mountain pine beetle ( <i>Dendroctonus ponderosae</i> ) survives prolonged exposure to stressful cold by mitigating ionoregulatory collapse Open
Insect performance is linked to environmental temperature, and surviving through winter represents a key challenge for temperate, alpine and polar species. To overwinter, insects have adapted a range of strategies to become truly cold hard…

The freeze-avoiding mountain pine beetle (Dendroctonus ponderosae) survives prolonged exposure to stressful cold by mitigating ionoregulatory collapse Open
Insect performance is intrinsically linked to environmental temperature, and surviving through winter represents a key challenge for temperate, alpine, and polar species. To overwinter, insects have adapted a wide range of strategies to be…

Diapause survival requires a temperature-sensitive preparatory period Open
Diapause is a form of internally-controlled dormancy that allows insects to avoid stressful conditions and periods of low food availability. Eastern spruce budworm (Choristoneura fumiferana Clemens), like many cold-adapted insects, enter d…

Transcriptome profiling of Fraxinus excelsior genotypes infested by emerald ash borer Open
European ash, Fraxinus excelsior is facing the double threat of ongoing devastation by the invasive fungal pathogen, Hymenoscyphus fraxineus and the imminent arrival of the non-native emerald ash borer (EAB), Agrilus planipennis . The spre…

A glimmer of hope – ash genotypes with increased resistance to ash dieback pathogen show cross‐resistance to emerald ash borer Open
Summary Plants rely on cross‐resistance traits to defend against multiple, phylogenetically distinct enemies. These traits are often the result of long co‐evolutionary histories. Biological invasions can force naïve plants to cope with nov…

Genome-wide markers show continental structuring and mitonuclear discordance in the forest tent caterpillar (<i>Malacosoma disstria</i> Hübner) (Lepidoptera: Lasiocampidae) Open
The forest tent caterpillar, Malacosoma disstria Hübner (Lepidoptera: Lasiocampidae), is an irruptive forest pest found throughout North America. Widespread species such as M. disstria are exposed to historical and contemporary processes t…

Molecular signatures of diapause in the Asian longhorned beetle: Gene expression Open
Most previous studies on gene expression during insect diapause do not address among-tissue variation in physiological processes. We measured transcriptomic changes during larval diapause in the Asian longhorned beetle, Anoplophora glabrip…

The Spruce Budworm Genome: Reconstructing the Evolutionary History of Antifreeze Proteins Open
Insects have developed various adaptations to survive harsh winter conditions. Among freeze-intolerant species, some produce “antifreeze proteins” (AFPs) that bind to nascent ice crystals and inhibit further ice growth. Such is the case of…
