Carrier pigs blamed for swine erysipelas outbreaks
USDA ARS findings identify apparently healthy carrier swine as the probable main source of sudden erysipelas outbreaks in hog herds. Dr. Wood's tests show the bacterium Erysipelothrix rhysiopathiae persists in feces and soil under certain conditions, with survival times from 52 hours to 32 days, influencing disease spread and carcass condemnation.

Disease-causing organism found in swine samples across farms
Researchers report that 2.63 percent of samples from four farms contained isolates causing disease in specific pathogen-free pigs. The organism appeared in sows, pigs, and hoglot soil. Dr Wood estimates contaminated feces from 400 hogs could exceed 11 pounds daily and may sustain transmission to hoglets.

Sex attractants offer alternative to pesticides for codling moths
USDA scientists report natural and synthetic pheromones can reduce codling moth damage in apples. In a Beltsville Yakima ARS study, one acre treated with pheromone capsules and 1 000 sterile moths disrupted male orientation, halting mating and signaling potential for field testing with further releases to assess reproduction effects.
