Prey Suitability and Phenology of Leucopis spp. (Diptera: Chamaemyiidae) Associated With Hemlock Woolly Adelgid (Hemiptera: Adelgidae) in the Pacific Northwest

Creator:: Grubin, Sarah M., Ross, Darrell W., and Wallin, Kimberly F.
Abstract:: Leucopis spp. (Diptera: Chamaemyiidae) from the Pacific Northwest previously were identified as potential biological control agents for the hemlock woolly adelgid, Adelges tsugae Annand (Hemiptera: Adelgidae), in the eastern United States. We collected Leucopis spp. larvae from A. tsugae infested western hemlocks in Oregon and Washington and reared them on...

Predicting Dendroctonus pseudotsugae (Coleoptera: Curculionidae) Antiaggregation Pheromone Concentrations using an Instantaneous Puff Dispersion Model

Creator:: Strand, Tara M., Ross, Darrell W., Thistle, Harold W., Ragenovich, Iral R., Guerra, Ivonne Matos, and Lamb, Brian K.
Abstract:: An instantaneous puff dispersion model was used to assess concentration fields of the Douglas-fir beetle, Dendroctonus pseudotsugae Hopkins, antiaggregation pheromone, 3-methylcyclohex-2-en-1-one (MCH), within a 1-ha circular plot. Several combinations of MCH release rate and releaser spacing were modeled to theoretically analyze optimal deployment strategies. The combinations of MCH release rate...

Controlled Release Fumigation of the Greater Wax Moth

Creator:: Burgett, D. Michael and Tremblay, Alan
Abstract:: Polyethylene film controlled release packets utilizing ethylene dibromide (EDB) and pdichlorobenzene (PDB) were designed and tested against late instar larvae of Galleria mellonella (L.). EDB controlled release packets gave 100% control of larvae in 48 h under experimental conditions at 26.6° and 32.3°C. PDB controlled release packets gave 13.3 and...

Suppression of Hop Looper (Lepidoptera: Noctuidae) by the Fungicide Pyraclostrobin

Creator:: Woods, J. L. and Gent, D. H.
Abstract:: The hop looper, Hypena humuli Harris, is a reemergent pest of hop that often requires treatment to mitigate crop damage. In 4 yr of field trials, plots treated with fungicides were observed to sustain less hop looper defoliation compared with nontreated plots. Further investigation revealed that abundance of hop looper...

Molecular Survey for the Invasive Leafminer Pest Liriomyza huidobrensis (Diptera: Agromyzidae) in California Uncovers Only the Native Pest Liriomyza langei

Creator:: Scheffer, Sonja J., Lewis, Matthew L., Gaimari, Stephen D., and Reitz, Stuart R.
Abstract:: Liriomyza huidobrensis (Blanchard) is a highly destructive invasive leafminer pest currently causing extensive damage to vegetable and horticultural crops around the world. Liriomyza langei Frick is a leafminer pest native to California that cannot currently be morphologically distinguished from L. huidobrensis. We used a DNA-barcoding approach, a published PCR-RFLP method,...

Location of the Mechanism of Resistance to Amphorophora agathonica (Hemiptera: Aphididae) in Red Raspberry

Creator:: Lightle, D. M., Dossett, M., Backus, E. A., and Lee, J. C.
Abstract:: The aphid Amphorophora agathonica Hottes (Hemiptera: Aphididae) is an important virus vector in red (Rubus idaeus L.) and black (Rubus occidentalis L.) raspberries in North America. Raspberry resistance to A. agathonica in the form of a single dominant gene named Ag1 has been relied upon to help control aphid-transmitted plant...

Developing Models for the Forage Ratios of Culiseta melanura and Culex erraticus using Species Characteristics for Avian Hosts

Creator:: Estep, Laura K., McClure, Christopher J. W., Burkett-Cadena, Nathan D., Hassan, Hassan K., Unnasch, Thomas R., and Hill, Geoffrey E.
Abstract:: Studies of mosquito preferences for avian hosts have found that some bird species are at greater risk than others of being fed upon by mosquitoes. The ecological factors that determine this interspecific variation in avian host use by mosquitoes have been little studied, despite the possibility that such variation may...

Population Density and Phenology of Tetranychus urticae (Acari: Tetranychidae) in Hop is Linked to the Timing of Sulfur Applications

Creator:: Woods, J. L., Dreves, A. J., Fisher, Glenn C., James, David G., Wright, Larry C., and Gent, D. H.
Abstract:: The twospotted spider mite, Tetranychus urticae Koch, is a worldwide pest of numerous agronomic and horticultural plants. Sulfur fungicides are known to induce outbreaks of this pest on several crops, although mechanisms associated with sulfur-induced mite outbreaks are largely unknown. Studies were conducted during 2007–2009 in Oregon and Washington hop...

Laboratory Bioassays to Estimate the Lethal and Sublethal Effects of Various Insecticides and Fungicides on Deraeocoris brevis (Uhler) (Hemiptera: Miridae)

Creator:: Amarasekare, K. G. and Shearer, P. W.
Abstract:: This laboratory bioassay focused on lethal and sublethal effects of five insecticides (chlorantraniliprole, cyantraniliprole, spinetoram, novaluron, and lambda-cyhalothrin) and two fungicide treatments (sulfur and a mixture of copper hydroxide and mancozeb) on the predatory mired bug Deraeocoris brevis (Uhler) (Hemiptera: Miridae) using second instars and adult males and females. Formulated...
