Life History Of Paracantha Gentilis (Diptera: Tephritidae), David H. Headrick, Richard D. Goeden
Life History Of Paracantha Gentilis (Diptera: Tephritidae), David H. Headrick, Richard D. Goeden
Horticulture and Crop Science
The life history of Paracantha gentilis Hering in southern California is described. This stenophagous tephritid reproduces in the capitula of native Cirsium thistles. Courtship and mating behavior are described from field and laboratory observations. Territorial and courtship behavior of males and the morphological characters involved in possible male pheromone emission are described and illustrated, as are the oviposition behavior and reproductive morphology of females. Egg clutch sizes ranged from one to 13 eggs, with a maximum of six clutches per capitulum. Larvae fed gregariously within stage-specific niches. Pupariation occurred in the capitula, from which adults emerged in mid-June through early …

Spray Drift Reduction With Shrouded Boom Sprayers, Ronald J. Fehringer, Richard Cavaletto
BioResource and Agricultural Engineering
Downwind drift was measured from a standard boom sprayer and a shrouded boom sprayer. Using 8002 flat fan nozzles, the hooded sprayer provided a 180 to 275% reduction in drift. The effectiveness of the shroud is dependent upon the spray droplet spectrum.

Irrigation District Canal Automation - Cardd, Charles M. Burt
Irrigation District Canal Automation - Cardd, Charles M. Burt
BioResource and Agricultural Engineering
The first rule regarding irrigation district canal automation is that there is no single "best" method of automations. The locations of buffer reservoirs, the ability to allow water to spill at the ends of canals, the storage capacity of canal pools, and the topography will also play key roles in deciding if automation is desirable, and what type of automation should be used. These typical engineering considerations must also be coupled with recognition of the limitations and abilities of irrigation district staff regarding maintenance and trouble shooting of sophisticated controls.

Structure And Morphology Of Magnetite Anaerobically-Produced By A Marine Magnetotactic Bacterium And A Dissimilatory Iron-Reducing Bacterium, N. H. C. Sparks, Stephen Mann, D. A. Bazylinski, D. R. Lovley, H. W. Jannasch, Richard B. Frankel

Physics
Intracellular crystals of magnetite synthesized by cells of the magnetotactic vibroid organism, MV-1, and extracellular crystals of magnetite produced by the non-magnetotactic dissimilatory iron-reducing bacterium strain GS-15, were examined using high-resolution transmission electron microscopy, electron diffraction and 57Fe Mo¨ssbauer spectroscopy. The magnetotactic bacterium contained a single chain of approximately 10 crystals aligned along the long axis of the cell. The crystals were essentially pure stoichiometric magnetite. When viewed along the crystal long axis the particles had a hexagonal cross-section whereas side-on they appeared as rectangules or truncated rectangles of average dimension, 53 × 35 nm. These findings are explained …
