Effects of Different Infestation Levels of the Twospotted Spider Mite on Strawberry Yield in Winter Plantings in Southern California
Effects of different infestation levels of Tetranychus urticae Koch on fruit yield and size were studied in a winter planting of strawberries in southern California in 1979 and 1980. Seasonal
New insights into the phylogenetics and population structure of the prairie falcon (Falco mexicanus)
California’s prairie falcons might be managed as a single population, indicating that management actions undertaken to benefit the species at the local level have the potential to influence the species as a whole.
Reductions in Plant Processes by Tetranychus urticae (Acari: Tetranychidae) Feeding on Strawberry
A sequenced mite-day model is presented and includes pertinent points on the population curve where the plant processes were reduced by 10% and the significance of the sequence in which the plant process were reduced is discussed.
The Effects of Acaricides on the Physiology, Growth, and Yield of Strawberries
The influence of various acaricides on strawberry plant physiology, growth, and yield of the ‘Tufts’ variety strawberry was quantified. The mechanisms of pesticide-induced phytotoxicity were also
Effect of Various Pesticides on Lettuce Physiology and Yield
Results indicate that the use of the dual-isotope porometer has great potential in monitoring subtle changes in plant photosynthesis and stomatal conductance rates caused by pesticides.
Pesticides may reduce lettuce yield
Insecticides tested on lettuce as weekly or twice- weekly preventive treatments reduced yields by affecting plant physiology.
Physiological Responses of Avocado Leaves to Avocado Brown Mite Feeding Injury
Stomatal and mesophyll conductance values, photosynthesis, and transpiration were found to be negatively correlated with increasing levels of spider mite injury and avocado photosynthesis rates were reduced when 100% feeding injury was sustained on the upper leaf surface.
Taxonomy of Streptanthus sect. Biennes , the Streptanthus morrisonii complex (Brassicaceae)
A study of the biochemistry, morphology, and distribution of the Streptanthus morrisonii section to evaluate the existing taxonomy and to determine the taxonomie status of newly-discovered populations.
