Abstract The southern pine beetle, Dendroctonus frontalis (Coleoptera: Curculionidae) (SPB), is known to be a major bark beetle pest of pines throughout the southeastern United States. A common predator of bark beetles, Thanasimus dubius (Coleoptera: Cleridae), has...
Abstract 1 The checkered beetle Thanasimus dubius (Fabricius) (Coleoptera: Cleridae) is a common predator in North America that feeds on bark beetles (mostly Ips and Dendroctonus spp.) (Coleoptera: Curculionidae: Scolytinae). Despite numerous field-trapping studies on...
Abstract Insects and diseases annually cause millions of hectares of defoliation and mortality to forested landscapes in the U.S. To monitor these disturbance events, the USDA Forest Service, Forest Health Protection and cooperating state partners conduct...
Abstract The southern pine beetle (Dendroctonus frontalis) (SPB) is an eruptive pest of pine forests in the southeastern United States. Numerous studies have been conducted on the relationships among SPB population dynamics, climatic factors, natural enemies, and...
Abstract The southern pine beetle (SPB) Dendroctonus frontalis Zimmermann, is the most important insect pest of pines in the southeastern United States, with outbreaks often resulting in thousands of hectares of pine mortality. Natural enemies and competitors have...
Abstract The southern pine beetle, Dendroctonus frontalis Zimmermann, has three population phases. In the latent phase, southern pine beetle-initiated infestations are absent, and southern pine beetle functions as a secondary bark beetle when present. The outbreak...
Abstract Introduction: In the United States of America, forest pests are associated with climate variability. Such studies are scarce in Mexico. Objectives: To create a data base of historical outbreaks of bark beetles and analyze their relationship with drought....
Abstract The southern pine beetle has shown a dramatic decline in outbreak activity over much of the southeastern United States since the turn of the 21st century compared to previous decades. Concurrently, from the 1950s through the present day, a twenty-fold...
Abstract The taxonomic status of Dendroctonus vitei Wood (Coleoptera: Curculionidae: Scolytinae) and Dendroctonus mexicanus Hopkins is supported by biological and morphological data. However, the differentiation of these species has been extremely difficult because...
