Abstract: This invention is a delivery system to deliver biologics such as vaccines or chemicals such as chemosterilants, repellents, or toxicants to free-roaming or wild animals such as raccoons, dogs, or foxes, without capture or physical restraint. The biologic or chemical is placed in a water-proof ampule or capsule which is imbedded in a synthetic bait comprising attractants and other additives on a polymeric support. The product will stimulate the target species to chew sufficiently that the active agent will be expelled in the oralpharyngeal cavity, particularly against the buccal mucosa. The specific adaptations of the invention depend on the eating habits of the animal species targeted.

Abstract: Devices for loading beneficial insect eggs are disclosed which have a string supply, an egg receptacle, and a provision for applying glue. The devices provide an economical and alternative strategy for the delivery of beneficial insect eggs to agricultural commodities.

Abstract: The present invention comprises apparatus designed to repel, but not injure, warm-blooded aquatic life from a specific aquatic region in an energy-efficient manner. A potential gradient is turned on and maintained between sets of immersed electrodes in response to the detection of the presence of warm-blooded animals in the "watched" volume at the surface and above and below the surface of an aquatic region. The electroshock is applied to the animal through the water by use of an electrical field generated from an array of electrodes placed in the water. The size, shape, and intensity of the electrical field are independently controlled by use of design criteria which allow the operator to determine the degree of electrical shock to be administered to a specific animal species by controlling the parameters of electrical energy induced into the animal through the water.

Abstract: The continuous removal of solid products from a high-pressure system is achieved by operating a high-pressure pump in reverse to gradually reduce pressure at the exit line to atmospheric pressure. This process allows solid products to exit the system while at the same time maintaining high pressure in the reactor.

Abstract: The present invention is drawn to isolates of Candida oleophila which are effective for the control of postharvest diseases in fruit and to biocontrol compositions which include such isolates. A method of utilizing the isolates to inhibit pathogens which cause postharvest diseases is also described. The organisms were isolated from the surface of tomato fruit and are useful for the control of a variety of fruit-rot pathogens in a variety of fruits.
