Vittatalactone is the Male-Produced Aggregation Pheromone of the Western Striped Cucumber Beetle, Acalymma trivittatum.

We found that vittatalactone, specifically (3R,4R)-3-methyl-4-[(1S,3S,5S)-1,3,5,7-tetramethyloctyl]oxetan-2-one, is the male-produced aggregation pheromone of the western striped cucumber beetle, Acalymma trivittatum (Mannerheim), as was previously shown for the striped cucumber beetle, Acalymma vittatum (F.) (Coleoptera: Chrysomelidae). A synthetic mixture containing 9% of the authentic natural pheromone, is attractive to both sexes of both species in the field, as demonstrated by trapping using baited and unbaited sticky panels in California and earlier in Maryland. Females of both species do not produce detectable vittatalactone. This finding expands the usefulness of the synthetic vittatalactone mixture for pest management throughout the range of both A. vittatum and A. trivittatum. Development of vittatalactone time-release formulations combined with cucurbitacin feeding stimulants offer the potential for selective and environmentally-friendly cucurbit pest management tactics.

Relación Del Estado Nutricional Con El Desarrollo Cognitivo Y Psicomotor De Los Niños En La Primera Infancia / Relationship Between Nutritional Status And Cognitive And Psychomotor Development Of Children In Early Childhood

RESUMEN La gestación, los primeros años de vida y el estado nutricional juegan un papel importante en el desarrollo físico, psicosocial, emocional y cognitivo en la infancia y adolescencia. Diferentes investigaciones han encontrado una relación entre el estado nutricional con un mejor desempeño cognitivo, por el contrario, la malnutrición en estas etapas puede ocasionar desequilibrios entre las necesidades nutricionales que podrían llevar a que se presente obesidad o desnutrición e influir sobre el desarrollo cognitivo. El objetivo de este artículo fue revisar la relación del estado nutricional con el desarrollo cognitivo y psicomotor de los niños en la primera infancia. El método fue revisión sistemática en las bases de datos ProQuest, Redalyc, Science Direct y Scopus en los años 2013-2018. Este artículo concluye que tanto la capacidad intelectual como el desarrollo de la motricidad fina y gruesa, dependen del estado nutricional de los infantes y por tanto se sugiere una relación entre la nutrición y el desarrollo psicomotor y cognitivo.

ABSTRACT Gestation, the first years of life and nutritional status are important role in physical, psychosocial, emotional and cognitive development in childhood and adolescence. Different investigations have found a relationship between nutritional status with better cognitive performance, although conversely, malnutrition in these stages can cause imbalances between nutritional needs that could lead to obesity or malnutrition and influence cognitive development. The aim of this article was to review the relationship between nutritional status and cognitive and psychomotor development of children in early childhood. The method was systematic review in the databases ProQuest, Redalyc, Science Direct and Scopus in the years 2013-2018. This article concludes that both the intellectual capacity and the development of fine and gross motor skills depend on the nutritional status of infants and therefore a relationship between nutrition and psychomotor and cognitive development is suggested.
