Pollination and pollinators of pumpkin and squash (Cucurbita maxima Duchesne) grown for seed production in the Willamette Valley of western Oregon

Creator:: Gavilánez-Slone, Jenny M.
Abstract:: 'Golden Delicious' winter squash (GDWS), Cucurbita maxima Duchesne, provides significant amounts of pollen (24 mg) and nectar (236 μl), but with a low reward of 14% nectar sugar. The quantity of nectar produced per GDWS flower differed between sites and floral sex. The GDWS male flowers had 25% higher sugar...

Predation on the western honey bee, Apis mellifera L., by the hornet, Vespa tropica (L.)

Creator:: Burgett, D. Michael and Akratanakul, Pongthep
Abstract:: Hornets of the genus Vespa are recognized as efficient and devastating predators of honey bees, especially in tropical and subtropical biomes. Of the four species of honey bees in the genus Apis only A. dorsata Fabr., the giant honey bee, appears free from attack by hornets (Seeley et al. 1982)....

Gordon Michael Final Thesis.pdf

Creator:: Gordon, Michael Ian
Abstract:: Anaerobic digestion of lipid-extracted algal biomass has been proposed as a method to recover and recycle nutrients in algal biofuel systems. The purpose of this study was to quantify recoverable nitrogen and phosphorus from anaerobically digested C. vulgaris. Recoverable nutrients were deemed those present in the liquid phase of anaerobic...

Screening for Viral Disease in the OSU Tomato Breeding Program

Creator:: Kershner, Alexandria C.
Abstract:: Disease control is a crucial aspect of plant breeding for researchers as well as commercial producers. After samples from OSU's tomato breeding program tested positive for Columnea latent viroid in a screen done by a private company, secondary testing was done by the USDA laboratory in Corvallis which suggested that...

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...

Apis florea drone flight: longevity and flight performance

Creator:: Buawangpang, Ninat, Sukumalanand, Prachaval, and Burgett, D. Michael
Abstract:: Mating flight records are presented for males (drones) of the Asian dwarf honeybee species Apis florea. These include observations on longevity, mortality and inclusive flight records for a cohort of known-aged males. Averages for flight performance show the flights/lifetime to be 15.3 (± 11.8 SD); the number of flight days,...

Honey bee (Apis mellifera) colony strength and its effects on pollination and yield in highbush blueberries (Vaccinium corymbosum)

Creator:: Grant, Kennedy J.
Abstract:: Many pollination studies with honey bees have examined the effect of colony density on crop yield and yet overlook the effect of variation in the population size of these colonies. High colony density in northern highbush blueberry has been met with concerns from beekeepers who feel higher densities will intensify...

The role of body size in the foraging strategies and management of avian herbivores : a comparison of dusky Canada geese (Branta canadensis occidentalis) and cackling geese (B. hutchinsii minima) wintering in the Willamette Valley of Oregon

Creator:: Mini, Anne E.
Abstract:: Body size explains much of the interspecific variation in the physiology, behavior, and morphology of birds, such as metabolic rate, diet selection, intake rate, gut size, and bill size. Based on mass-specific metabolic requirements and relative energetic costs of activities, being a certain body size has both advantages and disadvantages....

The Occurrence of Acarapis dorsalis, Acarapis externus and Acarapis woodi Mites in honey bee populations surrounding Poitiers, France

Creator:: Jillson, Katherine M.
Abstract:: Acarapis mites have been present in the United States since 1984 and are presently considered a threat to honey bee populations in North America. They have been present in Europe since 1921 where infestation rates have now dwindled to a level that is not considered dangerous. Consequently, accurate information on...

Consequences of coumaphos and Varroa destructor on drone honey bee sperm quantity

Creator:: Delaney, Deborah Anne
Abstract:: The number of drones and genetic diversity among drones are essential components to a well mated queen. Varroa destructor preferentially parasitizes drone brood, and is thought to be responsible for the loss of feral populations that once provided additional drones for honey bee mating areas. It is necessary to use...
