Behavioral response of moose Alces alces to summer heat stress

Wildlife Biology, EarlyView.
Minnesota moose are heat‐stressed during summers, which is adversely impacting their survival. We used both movement and activity data to explore the behavioral responses of Minnesota moose experiencing heat stress, termed ‘hot moose events' or HMEs, to understand how both ambient temperature and available habitat contribute to the ability of these ...

Abundance of Dendroctonus frontalis and D. mexicanus (Coleoptera: Scolytinae) along altitudinal transects in Mexico: Implications of climatic change for forest conservation.

PLoS ONE, 2023
Bark beetle infestations have historically been primary drivers of stand thinning in Mexican pine forests. However, bark beetle impacts have become increasingly extensive and intense, apparently associated with climate change.

Bacterial and fungal symbionts of parasiticDendroctonusbark beetles [PDF]

FEMS Microbiology Ecology, 2016
Bark beetles (Curculionidae: Scolytinae) are one of the most species-rich herbivorous insect groups with many shifts in ecology and host-plant use, which may be mediated by their bacterial and fungal symbionts. While symbionts are well studied in economically important, tree-killing species, little is known about parasitic species whose broods develop ...

Silencing of juvenile hormone‐related genes through RNA interference leads to molt failure and high mortality in the spongy moth

Insect Science, EarlyView.
The feasibility of using RNA interference to control the globally important quarantine pest, the spongy moth. Targeting genes related to JHs play an important role in the growth and development of insects. First, the open reading frames (ORFs) of Ldjhamt and Ldjheh were identified and characterized, and the target genes were cloned and double‐stranded ...

Cryptic Species Discrimination in Western Pine Beetle, Dendroctonus brevicomis LeConte (Curculionidae: Scolytinae), Based on Morphological Characters and Geometric Morphometrics

Insects, 2019
The western pine beetle (WPB), Dendroctonus brevicomis LeConte, is a major mortality agent of pines in North America. A total of 706 adults of WPB from 81 geographical sites were analyzed with traditional and geometric morphometric methods to evaluate ...

Dendroctonus frontalis and Pinus taeda

, 2018
It has been said by many that the native Southern Pine beetle, Dendroctonus frontalis, is one of the most destructive insect pests to pines. Here at Chincoteague National Wildlife Refuge, Loblolly Pine trees are a haven to the Southern Pine beetle for ...

Temperature interacts with jack pine host defences to influence the growth of mountain pine beetle‐associated fungi

Agricultural and Forest Entomology, EarlyView.
Optimal growing temperatures varied with mountain pine beetle‐associated fungal species. There was only a marginal impact of temperature on the response of fungi to defensive monoterpenes of novel host pine. Interspecific facilitation occurred for Leptiographuim longiclavatum when grown in Ophiostoma montium‐induced treatments at optimal temperatures ...

Chromosome-level genome assembly and population genomic analyses provide insights into adaptive evolution of the red turpentine beetle, Dendroctonus valens

BMC Biology, 2022
Background Biological invasions are responsible for substantial environmental and economic losses. The red turpentine beetle (RTB), Dendroctonus valens LeConte, is an important invasive bark beetle from North America that has caused substantial tree ...
