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 100 eggs of the bronze bug and a solution of water and honey. During 30 generations, rearing quality parameters were compared against expected quality standards set a priori, based on information from other rearing colonies. We also assessed the effect of temperature on developmental time, measured as the first day of emergence of adult parasitoids, as well as the relation between host-egg abortion and parasitization by C. noackae, and the evolution of 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. The percentage of females was slightly above 50%. Rearing at 18 °C and 20 °C took longer than at 22 °C, 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. Fieldcollected parasitoids exhibited better quality indices than individuals from the laboratory rearing. Results indicate that biological control of the bronze bug with C. noackae is feasible with this rearing and release protocol.

Abstract:
The objective was to evaluate the effect of the Holstein genotype (North American Holstein vs. New Zealand Holstein; NAH vs. NZH, respectively) in a pasture-based system on heat production (HP), energy partitioning between maintenance and production (milk and tissue) and energy efficiency during two different stages of lactation. Twenty-eight Holstein dairy cows (14 cows of each genotype) with similar calving date (May 5, 2018 ± 23 days) were managed in a pasture-based system and supplemented with one third of the predicted total dry matter intake as concentrate. Heat production, retained energy in milk and tissue, metabolizable energy intake (MEI) and the proportion of MEI retained in milk + tissue (RE/MEI) were measured at 115 and 192 ± 19 days in milk and residual HP was estimated by the difference between measured HP and predicted HP based on NRC (2001) model according to body weight, body condition score and milk production. The NAH cows were 60 ± 15 kg heavier and produced 4.7 ± 1.0 kg/d more milk with lower percentages of fat and protein than NZH cows. However, there were no differences in fat or protein yield per day between genotypes. Metabolizable energy intake, retained energy in milk and tissue, HP and RE/MEI were not different between genotypes at 115 days in milk. Nevertheless, at 192 days in milk the MEI, HP and residual HP were lower in NZH than NAH, whereas RE/MEI was not different when both genotypes were managed under a pasture-based system with one third of the consumed diet as concentrate. The capacity of NZH cows to maintain the same RE/MEI than NAH cows at 192 days in milk despite of the lower MEI, was due to a lower metabolizable energy requirement for maintenance (853 vs. 729 kJ/body weight0.75 per day for NAH and NZH, respectively). Indeed, the lower energy requirement for maintenance in NZH was associated with a lower fasting heat production since kl were not different between genotypes. Thus, NZH cows could have a lower proportion of their body as protein mass or a lower relative mass of the internal organs involved with digestive and circulatory functions. However, further investigation is necessary to understand the differences in maintenance energy requirements between the Holstein genotypes. MenosAbstract:
