Using targeted sequencing and TaqMan approaches to detect acaricide (bifenthrin, bifenazate, and etoxazole) resistance associated SNPs in Tetranychus urticae collected from peppermint fields and hop yards Open
Tetranychus urticae (Koch) is an economically important pest of many agricultural commodities world-wide. Multiple acaricides, including bifenazate, bifenthrin, and extoxazole, are currently registered to control T . urticae . However, pop…
Multiplex Polymerase Chain Reaction Reveals Unique Trends in Pathogen and Parasitoid Infestations of Alfalfa Leafcutting Brood Cells Open
The alfalfa leafcutting bee Megachile rotundata Fabricius (HYMENOPTERA: Megachilidae) is an important pollinator for multiple agricultural seed commodities in the United States. M. rotundata is a solitary cavity nesting bee that forms broo…
Examining Historical Rates of Leafcutting Bee Brood Cell Pathogens, Parasitoids, and Predators to Establish Baseline Infectivity Rates for Alfalfa Seed Growers Open
The alfalfa leafcutting bee Megachile rotundata (Fabricius) (Hymenoptera: Megachilidae) is the primary pollinator for the alfalfa seed industry. It is a solitary cavity nesting bee that utilizes leaf lined brood cells provisioned with poll…

Registration of high‐yielding aroma hop (<i>Humulus lupulus</i> L.) cultivar ‘USDA Triumph’ Open
Brewers consistently look for new and unique hop ( Humulus lupulus L.) cultivars that possess excellent flavor profiles and are cost effective to produce and utilize. Proprietary aroma cultivars have in some cases met this need but are cos…
Physiological resistance alters behavioral response of Tetranychus urticae to acaricides Open
Multiple acaricide resistance in Tetranychus urticae continues to threaten crop production globally, justifying the need to adequately study resistance for sustainable pest management. Most studies on acaricide resistance have focused on t…
RNA interference of NADPH-Cytochrome P450 reductase increases susceptibilities to multiple acaricides in <i>Tetranychus urticae</i> Open
The two-spotted spider mite, Tetranychus urticae , is a polyphagous pest feeding on over 1,100 plant species, including numerous highly valued economic crops. The control of T. urticae largely depends on the use of acaricides, which leads …
Assessing Transportation Impacts to Alkali Bees (Hymenoptera: Halictidae) and Alfalfa Seed Production in Southeastern Washington State Open
The Washington State Department of Transportation (WSDOT) is proposing safety improvements to U.S. Highway 12 near the town of Touchet, Washington. The improvements include realignment to the north in order to accommodate a wider roadway. …
