The relative impact of single vs. multiple agents on the biological control of Tansy ragwort (Senecio jacobaea)

Creator:: James, Rosalind R.
Abstract:: Field experiments were done to test the relative effectiveness of single and multiple biological control agents in reducing weed populations using two insects, the cinnabar moth, Tvria iacobaeae (L.), and the ragwort flea beetle, Lonqitarsus iacobaeae (Waterhouse).

Purification and properties of d'Anjou pear (Pyrus communis, L.) polyphenol oxidase

Creator:: Wissemann, Kimberly Warner
Abstract:: Polyphenol oxidase (PPO) from d'Anjou pears was purified and some molecular properties were studied. The extraction of PPO was accomplished in the presence of the phenolic binder AG 2X-8 and Triton X-100. Chlorophyll pigment was removed by chromatography resulting in a clear, colorless enzyme extract. Three fractions of pear PPO...

Purification of strawberry polyphenol oxidase and its role in anthocyanin degradation

Creator:: Wesche-Ebeling, Pedro Alfredo E.
Abstract:: Polyphenol oxidase (PPO) from strawberries was purified, partially characterized, and used to study its role in the degradation of anthocyanin pigments. The extraction method included the use of a buffered solution containing the phenolic binders Polyclar AT and Amberlite XAD-4. Addition of Triton X-100 resulted in an increase of the...

Biology of the yellowjacket parasitoid Bareogonalos canadensis (Harrington) (Hymenoptera: Trigonalyidae)

Creator:: Carmean, David
Abstract:: The known biology of Bareogonalos canadensis (Harrington) is based on literature records of six collections from three areas in the Pacific Northwest. The objective of this study was to obtain fundamental knowledge on the biology of B. canadensis, especially its distribution, abundance, and host species, as well as its potential...
