Evaluating the Impacts of Border Vegetation Patterns on Multifunctional Biodiversity and Crop Production in Washington Blueberry

Herbaceous flowering or woody plant borders are controversial in commercial blueberry production. Border vegetation has the potential to increase populations of native pollinators and beneficial…

Biodiversity and the Natural Suppression of Human Pathogens

Restoring livestock to mixed-vegetable farms allows on-farm fertilizer production and the sale of high-value meat products.  Likewise, diversifying farms with native plants provides habitat for…

Sequencing the genomes of two critically-important biological control agents, the insect-killing nematodes Steinernema feltiae and Heterorhabditis bacteriophora

Potatoes are a valuable Washington crop that is threatened by devastating insect pests. We have found (1) that insect-killing “entomopathogenic” nematodes (EPNs) are key natural…

Effects of Nematode Genetic Diversity on Management of Potato Pests

Market forces are driving conventional Columbia Basin potato growers towards less-chemically-intensive pest management approaches, such as biological control. Insect-killing, entomopathogenic nematodes (EPNs), which live in…

Local and landscape-scale conservation of beneficial predators in Columbia Basin Potato Crops

Biological control by naturally-occurring predatory insects and spiders is an ecologically friendly and sustainable approach to pest management. Biological control is often underutilized, however, in…

Conservation Biology of Syrphids, Predators of Woolly Aphid in Central Washington.

Woolly apple aphid Eriosoma lanigerum is a secondary pest whose outbreaks have occurred more often since about 2000. The increase in aphid outbreaks appears to…
