An analysis of costs and efficiencies in mechanical caneberry harvesting

Creator:: Clevenger, Thomas Scott
Abstract:: The purpose of this study, initiated early in the development of mechanical caneberry harvesting, was to provide timely information for early management decisions concerning mechanical harvesting. This was accomplished through an economic comparison of mechanical and hand harvesting of selected types and varieties of caneberries. Consideration was given to the...

OpMNPV p87, a baculovirus capsid protein : genetic location, nucleotide sequence, transcriptional mapping and immunochemical characterization

Creator:: Müller, Rolf
Abstract:: A capsid protein termed p87 of the Orgyia pseudotsugata multicapsid nuclear polyhedrosis virus (OpMNPV) was located to the HindIII-G fragment of the viral genome by Southern hybridization. A 3.6 kb segment of this region was sequenced and an 1872-nt open reading frame encoding the p 87 protein was identified and...

Survival and development of the flat-headed fir borer in forest residues as affected by host and microclimatic conditions

Creator:: Scott, Donald Wayne
Abstract:: The purpose of this study was to examine various host and microclimatic influences affecting the survival and development of the flatheaded fir borer, Melanophila drummondi (Kirby) in Douglas fir, Pseudotsuga menziesii (Mirbel) Franco residues. It also expands current knowledge of the biology, bionomics, life history, ecology, and biotic potential for...

Twospotted spider mite, Tetranychus urticae Kock, in Oregon peppermint, Mentha piperita L. : sampling, population dynamics and economic injury

Creator:: Hollingsworth, Craig Stephen
Abstract:: A pest management program for Tetranychus urticae Koch in Oregon peppermint was developed based on studies of sampling, plant phenology, population dynamics and damage thresholds. A sample size of 45 leaves provided a confidence level of 90% and a confidence interval of 50%. Estimation of the sample mean was based...

Hydrogen-stimulated CO₂ fixation and coordinate derepression of hydrogenase and ribulosebisphosphate carboxylase in a H₂-uptake positive strain of Rhizobium japonicum

Creator:: Simpson, Frank Berry
Abstract:: H₂-uptake positive strains (122 DES and SR) and H₂-uptake negative strains SR2 and SR3 of Rhizobium japonicum were examined for ribulosebisphosphate (RuBP) carboxylase and H₂-uptake activities during growth conditions which induced formation of the hydrogenase system. The rate of ¹⁴CO₂ uptake by hydrogenase-induced cells was about six times greater in...

Management of variegated cutworm in peppermint

Creator:: Coop, Leonard Bryan
Abstract:: A pest management program for variegated cutworm (VC), Peridroma saucia (Hubner), in Oregon peppermint was developed based on studies of pheromone trapping, sampling methods, and economic thresholds. Pheromone traps effectively trapped VC males and were used to reflect development and oviposition trends. Trap height was linearly correlated to moth catch...

Studies on resistance of rice to Sogatodes oryzicola (Muir) and a parasitoid, Haplogonatopus sp., in Costa Rica

Creator:: Alvarez B., Francisco
Abstract:: Twenty-one rice cultivars were evaluated to determine the difference between populations of Sogatodes oryzicola (Muir) (Homoptera: Delphacidae) in Costa Rica and Colombia, Survival, mortality and population development of S. oryzicola on five selected cultivars was used to determine levels of plant resistance. The importance and potential of the parasitoid-predator Haplogonatopus...
