Abstract Background Gut microbiota contribute to the health of their hosts, and alterations in the composition of this microbiota can lead to disease. Previously, we demonstrated that indigenous gut...

A major challenge to addressing biological invasions is that the need for emergency responses often precludes opportunities to analyze the dynamics between initial establishment and population...

We characterized gut microbial communities in the emerald ash borer, Agrilus planipennis Fairmaire, an invasive phloem-feeding and wood-boring beetle that has caused extensive mortality to urban and...

The spruce beetle, Dendroctonus rufipennis, is an eruptive forest pest of significant economic and ecological importance. D. rufipennis has symbiotic associations with a number of microorganisms,...

Biome-scale disturbances by eruptive herbivores provide valuable insights into species interactions, ecosystem function, and impacts of global change. We present a conceptual framework using one...

Host location by parasitoids and dipteran predators of bark beetles is poorly understood. Unlike coleopteran predators that locate prey by orienting to prey pheromones, wasps and flies often attack...
Signal Mimics Derived from a Metagenomic Analysis of the Gypsy Moth Gut Microbiota � † (2006)
Changhui Guan, Jianhua Ju, Bradley R. Borlee, Lynn L. Williamson, Ben Shen, Kenneth F. Raffa, ...
Bacterial signaling is an important part of community life, but little is known about the signal transduction pathways of the as-yet-uncultured members of microbial communities. To address this gap,...

The goal of this study was to characterize the cellulose-degrading microorganisms in the guts of wood-inhabiting beetles. We enriched for cellulose-degrading microorganisms by inoculating filter...

Conifer resin and phloem tissue contain several phytochemical groups, composed primarily of monoterpenes, diterpene acids, and stilbene phenolics. The effects of monoterpenes and phenolics on...

Efforts to describe the complex relationships between bark beetles and the ophiostomatoid (stain) fungi they transport have largely resulted in a dichotomous classification. These symbioses have been...

The pine engraver, Ips pini (Say), colonizes jack, red, and white pines in the Great Lakes region. Males select suitable hosts, bore through the bark into phloem tissue, and emit aggregation...

Seasonal activity of 24 species of ground-occurring, forest Coleoptera in northern Wisconsin and the Upper Peninsula of Michigan was assessed using pitfall traps during the spring and summer of 1996...

We sampled bark beetle (Coleoptera: Scolytidae) populations in 17 declining and healthy red pine plantations in Wisconsin over 3 yr. We tested for potential relationships among numbers of bark...

We examined genetic variation in host selection behavior of a phloeophagous insect herbivore. Data from paternal families of the bark beetle Ips pini (Say) were used to estimate the heritability of...

This study evaluated the effects of seasonal phenology on the substrate quality of susceptible hosts to the pine engraver, Ips pini (Say). We also determined the effects of the duration and method of...

A series of bioassays were performed to evaluate the effects of host tree monoterpenes on initial entry, within-tissue orientation, and gallery construction by the bark beetle Ips pini (Say)....

Estimating populations of both pest and natural enemy species is important in the planning and implementation of biological control. For example, synthetic pheromone lures are used to sample bark...

Mass-trapping using semiochemical lures is a potentially useful control measure against bark beetle pests. A serious problem, however, is the inadvertent removal of predators that respond to these...

Bacillus cereus French & French increased the mortality of 3rd-instar gypsy moths, Lymantria dispar (L.), caused by Bacillus thuringiensis subsp. kurstaki Berliner. B. cereus did not cause mortality...

Little is known about bacteria associated with Lepidoptera, the large group of mostly phytophagous insects comprising the moths and butterflies. We inventoried the larval midgut bacteria of a...

Midgut bacteria required for Bacillus thuringiensis insecticidal activity
Broderick, Nichole A., Raffa, Kenneth F., Handelsman, Jo
Bacillus thuringiensis is the most widely applied biological insecticide and is used to manage insects that affect forestry and agriculture and transmit human and animal pathogens. This ubiquitous...
Continuous time modelling of dynamical spatial lattice data observed at sparsely distributed times
Jakob G. Rasmussen, Jesper Møller, Brian H. Aukema, Kenneth F. Raffa, Jun Zhu
We consider statistical and computational aspects of simulation-based Bayesian inference for a spatial-temporal model based on a multivariate point process which is only observed at sparsely...
