Abstract: A preparation of Saccharomyces strains is used for reducing colonization by human enteropathogenic bacteria in poultry. This is referred to as a defined competitive exclusion preparation. It is especially effective for both Salmonella and Campylobacter.

Abstract: Agricultural methods of biological control and organisms useful in such methods are disclosed, such as novel endophytic symbiotic Bacillus subtilis and methods of biologically controlling fungal diseases of plants. These strains are useful vectors for the delivery of their beneficial gene products to plants.

Abstract: Hydrodynamic baits for the control of orthopterous insects are disclosed which contain an attractant, a humectant and a gel former. The baits are designed to function in harsh and/or dynamic microclimates such as for example commercial kitchens or outdoor environments subject to typical circadian influences such as temperature and moisture. A further advantage of the disclosed baits is their lack of attractiveness to mammals.

Abstract: A dry insect trap for capturing male and female frugivorous pest insects for detecting, monitoring, and/or controlling.

Abstract: An attractant composition has been discovered for the control of multiple species of pest arthropods, particularly multiple species of pest ants. The composition, which includes a sugar and a salt or base, and water, attracts both oil-loving and sweet-loving ants and is especially useful with water soluble or suspendable toxicants.

Abstract: Isochromans and their derivatives have been chemically synthesized. These compounds possess significant phytotoxic activity which may be used as a biodegradable contact herbicide. The synthetic method allows for economic production of these herbicides.

Abstract: A dry insect trap for capturing male and female frugivorous pest insects for detecting, monitoring, and/or controlling.

Abstract: A communications system is organized into a two or more levels of multiplexing modules. Each multiplexing module has a plurality of inputs from next level multiplexing modules, with the exception of the last level multiplexing modules. The last level multiplexing modules have a plurality of inputs from sensor modules outputting data. A default condition is set up to allow transmission of address information from the computer to all the multiplexing modules to allow the programming of each multiplexing module to select one of its inputs. At the appropriate time, timing circuitry in the multiplexing modules reverse the direction of communication of the multiplexing modules to allow a single sensor module to transmit its data to the computer, in accordance with the address information.

Abstract: A growth supplement for bacterial media is used to induce and/or maintain differentiation and viability of bacterial cell cultures. The supplement contains about 10 mM to about 100 mM of a sugar, an amino acid or mixtures thereof. When the media used does not contain iron and reducing agents, such as sodium thiosulfate, these are included in the supplement. The reducing agent is present preferably at about 20 to about 40 mM. The addition of this supplement results in flagellation of aflagellate variants of Salmonella and hyperflagellation of variants of Salmonella which are flagellated.

Abstract: An attractant for social pest insects has been discovered and isolated from soybean oil. This attractant is also found in canola oil. This attractant increases the effectiveness of baits and/or traps in the control of social pest insects.

Abstract: Aminoglycosides such as aminoglycoside antibiotics are detected and separated by non-immunoaffinity binding to an immobilized binding protein which is preferably lysozyme or .alpha.-lactalbumin. Aminoglycosides are detected in a biological sample such as milk or a fermentation broth by contacting the sample with the binding protein immobilized on a solid carrier such as particles of carboxylated latex to bind the aminoglycosides to the binding protein, adding a label that binds to the aminoglycosides and measuring the label. In another embodiment, the binding protein containing bound aminoglycosides is separated from the sample, the aminoglycosides are removed from the binding protein, a label is added to the aminoglycosides and the label is measured. Aminoglycosides are removed from a sample by passing the sample through a bioreactor containing the binding protein immobilized on a solid carrier to bind the aminoglycosides to the binding protein and recovering the sample free of aminoglycosides.

Abstract: Avian diseases, particularly those which threaten birds early in life, are controlled by embryonal vaccination using water-in-oil-in-water emulsion vaccines. The site of inoculation is the albumin end of the egg via entry through the air cell end of the egg.

Abstract: The present invention is directed to cultivated plants that contain the gene(s) from Pennisetum squamulatum which express apomixis. More specifically, it relates to apomictic backcross hybrids (BC) that closely resemble pearl millet in morphology and their progeny. These apomictic pearl millets are useful as forage or grain cultivars or used as male pollinators on sexual germplasm to produce new apomictic forage and grain hybrids. The plants can also be used as a source of the gene(s) for controlling apomixis in order to transfer the apomictic mechanism into other cultivated plants to develop true-breeding hybrids.

Abstract: A preparation from the scrapings of healthy animals is cultured and administered to animals. This preparation confers a strong measure of protection against the subsequent colonization by enteropathogenic bacteria, including Salmonella species, Campylobacter species and Escherichia coli 0157:H7, which currently cause an unacceptably high incidence of morbidity and mortality in humans and reduce productivity in livestock populations.

Abstract: A vacuum device having a hand-held intake and collection unit and a hand-held heater/air exhaust tube assembly is used to chase and collect pests, such as insects, and their associated allergens from their harborages. The device has a system of filter assemblies which remove contaminants from the air and exhausts clean air back into the surrounding environment.

Abstract: A variety of beneficial insects, from the egg stage to adult stage, have been successfully reared on a defined insect culture medium with a supplement containing poultry egg yolk, ground liver and glutamine. The medium contains no insect components. The medium is encapsulated to facilitate feeding and where applicable oviposition.

Abstract: A backpack sprayer for spraying arthropods or arthropod eggs, such as beneficial mites or beneficial insect eggs, or insect eggs containing parasitoids, directly onto plants is disclosed which uses excess air generated by a compressor to produce a coarse or fine spray of an aqueous suspension containing the arthropods or eggs as they exit from a spray gun. A stir bar magnet in a spray tank, controlled by a magnetic stirrer motor, keeps the arthropods or eggs evenly suspended in an aqueous solution. The sprayer provides an economical and alternative strategy for the delivery of arthropods such as beneficial mites and eggs to agricultural commodities.

Abstract: A trapping system for capturing male and female frugivorous pest insects for detecting, monitoring, and/or controlling that includes an attractant composition of ammonium acetate and putrescine and a synergist for the attractant composition.

Abstract: Avian diseases, particularly those which threaten birds early in life, are controlled by embryonal vaccination using oil emulsion vaccines. The site of inoculation is the albumin end of the egg via entry through the air cell end of the egg.

Abstract: A composition of a mixture of nonionic surfactants in water-in-oil emulsion vaccines allows the use of animal, vegetable, and synthetic oils as well as mineral oil and pristane. These non-mineral oil vaccines are as efficacious as mineral oil-containing vaccines without the problems associated with the use of mineral oil.
