Abstract-
We investigated the physiological relationship between diet during pregnancy and colostrum production in ewes to test the hypothesis that for ewes that are in low body condition, with low fat reserves, the food supply will be the main source of energy for colostrum synthesis. To this end, we measured the amount of colostrum accumulated by ewes under two levels of nutrition. We also measured the circulating concentrations of metabolites and hormones associated with lactogenesis (beta-hydroxybutyrate, glucose, progesterone, prolactin, cortisol, growth hormone, leptin, insulin and insulin-like growth factor-I) Ewes were either under-fed at 70 (n = 15) or well-fed at 110% (n = 10) of their daily metabolisable energy requirement during the last two months of pregnancy. Colostrum accumulation up to parturition was 168 +/-48 g for under-fed ewes and 451 +/-103 g for well-fed ewes. After birth, under-fed ewes produced less colostrum than well-fed ewes but the difference was no longer significant. The level of nutrition also influenced the plasma concentrations of hormones and metabolites related to lactogenesis. Progesterone concentrations decreased before lambing in all animals but in under-fed ewes the fall appeared to be too small to initiate the onset of colostrum production. Beta-hydroxybutyrate concentrations were higher in under-fed than in well-fed ewes, suggesting that the under-fed ewes were mobilising more adipose tissue but they still did not meet their ME requirements for colostrum production. We concluded that, in underfed ewes, there are insufficient nutrients for adequate lactation and the hormone regime is inappropriate for good udder development and colostrum synthesis. MenosAbstract-

El control biológico es la herramienta principal para el manejo de plagas forestales. Iniciamos un programa de control biológico para la chinche del eucalipto, Thaumastocoris peregrinus con la avispa parasitoide de huevos Cleruchoides noackae. Se importaron huevos parasitados desde una cría masiva en Brasil y se inició una colonia de cría. Las avispas fueron criadas en tubos de plástico con huevos del hospedero y una solución de agua y miel. Durante 30 generaciones, se comparó un conjunto de parámetros de calidad contra estándares establecidos a priori. También evaluamos el efecto de la temperatura sobre el tiempo de desarrollo, la relación entre el aborto de huevos y la exposición previa a C. noackae, así como la variación temporal de la razón sexual de los emergentes en una generación dada. A partir de marzo de 2013 y durante varios veranos se realizaron liberaciones a campo en plantaciones comerciales y campos experimentales. Las tasas de emergencia y de supervivencia fueron estables o se incrementaron a lo largo de 30 generaciones. La razón sexual mostró una ligera desviación hacia las hembras. El ciclo se enlenteció a 18º C con respecto a la cría a 22ºC pero sin afectar la productividad. El aborto de huevos del hospedero se incrementó como consecuencia de la exposición al parasitoide. La proporción de hembras aumentó a medida que progresó el periodo de emergencia en una generación. Relevamientos a campo en dos sitios revelaron que las avispas sobrevivieron por dos años. Los parasitoides colectados a campo presentaron mejores índices de calidad que los de la cría de laboratorio. Estos resultados confirman que implementar un programa de control biológico de la chinche del eucalipto con C. noackae es factible con este protocolo de cría y liberación // Biological Control is a major tool for forest
insect pest management. We initiated a Biological Control program for the Eucalyptus bronze bug, Thaumastocoris peregrinus, with
the egg parasitoid Cleruchoides noackae. Parasitized eggs were imported from a mass rearing in Brazil, and a rearing colony was
set up. The wasp was reared in plastic tubes each containing ten individuals that were offered eggs of the bronze bug and a solution
of water and honey. During 30 generations, we assessed rearing quality parameters and compared them against expected quality
standards set a priori. We also assessed the effect of temperature on developmental time, as well as the relation between host-egg
abortion and parasitization by C. noackae, and the sex ratio of the emergent wasps within a single generation. Field releases were
made yearly during summers in commercial plantations, starting in March 2013. Survival and emergence rates were either stable or increased throughout 30 generations. Sex ratio was female-biased. Rearing at 18 ºC took longer than at 22 ºC, but productivity
was similar. Host-egg abortion was increased by parasitization. The proportion of females increased as the emergence period progressed. Field surveys in two sites revealed that the wasp survived for two years. Field-collected parasitoids exhibited better quality indices than that of the laboratory rearing. These results confirm that Biological Control of the bronze bug with C. noackae is feasible with this rearing and release protocol.
