  • Patent number: 6772557
    Abstract: A termite bait station for installation in the ground includes a tubular outer housing and a tubular inner bait cartridge inserted into the housing, each having circumferentially elongate apertures therethrough to allow termites to access bait in the cartridge. Each aperture in the cartridge is disposed between a pair of spaced, parallel ribs that extend in the circumferential direction. The ribs reduce the radial gap that must be traversed by a termite passing from the outer housing to the bait cartridge. The ribs also form circumferentially extending channels for producing a channeling effect tending to lead termites into the apertures in the cartridge.

  • Patent number: 6774288
    Abstract: The present invention provides grain, seed, feed made from the grain or seed, petfood made from the grain, and food products made from the grain. The grain may be maize grain with the following characteristics: oil burdened, elevated protein content, and low phytate levels. The combination of oil burdened, protein laden, decreased phytate characteristics in grain makes a grain that provides more calories, protein and phosphorus and other nutrients to the feeding animal. Pet foods, and animal feds and corn food products made of the present invention will provide increased nutrition because of the increased bioavailability of the components of the grain.
