This moth was first reported on this continent as a pest in a consignment of peanuts, received in California from China (de Ong, 1919). Mr. Hahn W. Capps, of the United States Department of Agriculture, informs me, in litt., that 6 adults from that infestation, together with 2 from “near prunes” in 1930, and 8 from a prune warehouse in 1931, at San José, are in the U.S. National Museum.

Knowledge of what Precision Agriculture (PA) content is currently taught across the U.S. will help build a better understanding for what PA instructors should incorporate into their classes in the future. For this assessment, the University of Missouri (MU) partnered with several universities throughout the nation on a United States Department of Agriculture (USDA) challenge grant. A survey was conducted with PA instructors from 44 institutions from across the U.S. participating. Each institution was assessed to determine amount of time they spent teaching on 59 different PA topics in their PA-related courses. Results were obtained from 56 PA courses. Scope of PA, Global Positioning System (GPS), Differential GPS, Yield Monitoring, and Yield Map were all topics that were frequently discussed in PA courses, whether they were entryor advanced-level or two-year or four-year institutions. Review of the content showed a need for a more standardized curriculum.

Abstract The U.S. Department of Agriculture (USDA) yield grade (YG) equation is used to predict the retail yield of beef carcasses, which facilitates a more accurate payment for cattle when they are sold on a grid pricing system that considers carcass composition instead of body weight alone. The current USDA YG equation was developed over 50 yr ago. Arguably, the population of cattle used to develop the YG equation is different than the current diverse U.S. beef cattle supply today. The objectives of this manuscript are to promote the adoption and use of precision agriculture technologies (i.e., camera grading and electronic animal identification) throughout the U.S. beef supply chain as a means to enhance the ability of the USDA YG equation to more accurately predict the retail yield across the population of cattle that contributes to the current U.S. beef supply. Camera grading has improved the accuracy of determining beef carcass retail yield; however, the use of electronic animal identification would allow for additional information to be passed back and forth between the packer, cattle feeder, and producer. Information, such as sex, genetics, medical treatment history, diets consumed, and growth promotant administration, as well as other information could be used to create additional variables for a new augmented USDA YG equation. Herein, fabrication yields demonstrated a 5.6 USDA YG and 12.8% boneless closely trimmed retail cut difference between actual cutout measurements and calculated values from the USDA YG equation for Jersey-influenced cattle. Evidence of such disparities between calculated and actual values warrants a reevaluation of the USDA YG system and consideration for implementing advancements in precision agriculture to improve the prediction of beef carcass retail yield to more accurately account for the large amount of variation in beef carcass retail yield from the cattle in the United States.

At the time of my retirement on December 31, 1950, a number of notes on synonymy and generic transfers had accumulated. Many of these are thought worthy of publication and this paper is made up of a number of them. Those included notes which deal with Nearctic forms will clarify the treatment of certlin genera and species in the catalog of North American Hymenoptera, now in process of publication by the U.S. Department of Agiculture, the Chalcidoidea section of which catalog has assembled and edited by O. Peck of the Canadian Department of Agriculture but which is based in great part upon the classification and arrangement of the collection in the United States National Museum. The catalog will probably appear in print before this paper does. Several notes dealing with forms not known to occur in the Nearctic region, hence not appearing in the catalog, are also included.

A reduction in Campylobacter spp. has been associated with use of commercial antimicrobial technologies during the processing of broiler chickens. This review is focused on commercial interventions that have received approval by both the U.S. Food and Drug Administration and the U.S. Department of Agriculture for use on raw poultry in the United States. Most of these interventions are currently applied prechill. The limited number of publications on the topic suggests that the application of antimicrobials in commercial settings results in Campylobacter reduction of 1 to 2 log CFU/ml of carcass rinse. However, postchill counts of 0.5 to 1 log CFU/ml of carcass rinse (approximately 4,000 CFU per carcass) are still common. Thus, antimicrobial interventions are not a complete solution for the control of Campylobacter on raw poultry. New postchill interventions are needed, as are (i) improvements in the methodology for detection and enumeration of Campylobacter, (ii) additional surveys on the contamination of processed poultry, and (iii) an understanding of possible resistance to antimicrobials by Campylobacter spp. Research addressing these topics will lead to better control of Campylobacter in commercial poultry carcasses.
