Recovery of Penncap-M from Foraging Honey Bees and Pollen Storage Cells

Creator:: Burgett, D. Michael and Fisher, Glenn C.
Abstract:: Foraging honey bees (Apis mellifera L.), exposed to birdsfoot trefoil (Lotus corniculatus L.) bloom treated with microencapsulated methyl parathion, continued to display pollen and midgut microcapsule contamination up to 9 days postspray. Nearly 10% of all pollen storage cells examined in combs taken from honey bee colonies exposed to the...

Response of Higbbush Blueberry to Nitrogen Fertilizer during Field Establishment-II. Plant Nutrient Requirements in Relation to Nitrogen Fertilizer Supply

Creator:: Bryla, David R., Strik, Bernadine C., Banados, M. Pilar, and Righetti, Timothy L.
Abstract:: A study was done to determine the macro- and micronutrient requirements of young northern highbush blueberry plants (Vaccinium corymbosum L. ‘Bluecrop’) during the first 2 years of establishment and to examine how these requirements were affected by the amount of nitrogen (N) fertilizer applied. The plants were spaced 1.2 ×...

Response of Highbush Blueberry to Nitrogen Fertilizer During Field Establishment, I: Accumulation and Allocation of Fertilizer Nitrogen and Biomass

Creator:: Pilar Banados, M., Strik, Bernadine C., Bryla, David R., and Righetti, Timothy L.
Abstract:: The effects of nitrogen (N) fertilizer application on plant growth, N uptake, and biomass and N allocation in highbush blueberry (Vaccinium corymbosum L. 'Bluecrop') were determined during the first 2 years of field establishment. Plants were either grown without N fertilizer after planting (0N) or were fertilized with 50, 100,...

Acetyl-CoA Carboxylase Herbicide Tolerance in Bermudagrass

Creator:: Grimshaw, Austin L., Schwartz, Brian M., Grey, Timothy L., McCullough, Patrick E., Raymer, Paul L., Webster, Theodore M., Kowalewski, A. R., Tate, Trent M., and Parrott, Wayne A.
Abstract:: Contamination of newly planted bermudagrass (Cynodon spp.) varieties by undesirable off-type bermudagrass genotypes is an ever increasing concern for turf managers because selective control options are limited. In 2009, a sethoxydim {2-[1-(ethoxyimino)butyl]-5-[2-(ethylthio)propyl]-3-hydroxy-2-cyclohexen-1-one} tolerant bermudagrass genotype (93-175) was identified during herbicide screening at the University of Georgia in Tifton. The objective...

The need to breed crop varieties suitable for organic farming using wheat, tomato and broccoli as examples: A review

Creator:: Lammerts van Bueren, E. T., Jones, S. S., Tamm, L., Murphy, K. M., Myers, J. R., Leifert, C., and Messmer, M. M.
Abstract:: It is estimated that more than 95% of organic production is based on crop varieties that were bred for the conventional high-input sector. Recent studies have shown that such varieties lack important traits required under organic and low-input production conditions. This is primarily due to selection in conventional breeding programmes...

Assimilate Partitioning in Vitis vinifera During the Reproductive Period

Creator:: Finger, Sarah A. and Candolfi-Vasconcelos, M. Carmo
Abstract:: Objectives of proposed research: 1. Investigate the relationship between abscisic acid (ABA) and auxins and the regulation of carbon partitioning. 2. Investigate the origin of ABA present in the fruit during ripening and attempt to modify the partitioning pattern through manipulation of endogenous ABA levels using mefluidide (ABA biosynthesis promoter)...

Evaluation of methyl salicylate lures on populations of Typhlodromus pyri (Acari: Phytoseiidae) and other natural enemies in western Oregon vineyards

Creator:: Gadino, Angela N., Walton, Vaughn M., and Lee, Jana C.
Abstract:: Methyl salicylate (MeSA), a herbivore-induced plant volatile, can elicit control of pests through attraction of beneficial arthropods. This study evaluates the effect of synthetic MeSA lures (PredaLure) on arthropod populations during the 2009 and 2010 seasons in two Oregon vineyards (Dayton and Salem). MeSA lures were deployed at a low...

Impact of floral feeding on adult Drosophila suzukii survival and nutrient status

Creator:: Tochen, Samantha, Walton, Vaughn M., and Lee, Jana C.
Abstract:: Drosophila suzukii, spotted wing drosophila, is a serious pest of small fruits and cherries in many regions of the world. While host usage has been well studied at the ovipositional and larval feeding stages, little is known about the feeding ecology and nutrient requirements of adults. This study addressed the...

Host stage preference, efficacy and fecundity of parasitoids attacking Drosophila suzukii in newly invaded areas

Abstract:: Drosophila suzukii (Matsumura) (Diptera: Drosophilidae) causes severe damage to certain fruit crops in both North America and Europe. This may be due, in part, to the absence of specialized natural enemies that suppress population outbreaks. We performed a series of experiments under controlled laboratory conditions in tandem with a field...

Biophysical Effects and Ground Force of the Baldree Traffic Simulator

Creator:: Kowalewski, A. R., Schwartz, B. M., Grimshaw, A. L., Sullivan, D. G., Peake, J. B., Green, T. O., Rogers, J. N., III, Kaiser, L. J., and Clayton, H. M.
Abstract:: Traffic simulators are often utilized when researching turfgrass wear tolerance and recovery. However, the availability of a durable traffic simulator capable of producing dynamic force is limited. Therefore, the objectives of this research were to: 1) evaluate a novel traffic simulator with improved durability and capable of producing dynamic force...
