Abstract:
'Williams' is the most cultivated pear in Uruguay and requires more than 900 chill hours to exit from the endodormancy. When this condition is not satisfied, the application of budbreak promoters is necessary to facilitate the bud swelling. The experiments were carried out in a pear orchard of 'Williams' (Pyrus communis L.) located in the Experimental Station INIA Las Brujas, during the 2017-2018 season. The objective of the study was to evaluate the effect of budbreak promoter applications on budbreak. Two experiments were performed: Experiment 1 consisted in the application of Erger® 4%, Erger® 2% and mineral oil 4%, in two dates: August 15, 2017 and September 1, 2017. Experiment 2 consisted in the application of Erger® 8% and hydrogen cyanamide 1% on August 15, 2017 and Erger® 4% on September 28, 2017. In 2017 chill units in Uruguay were 187, while the average for the last 20 years is 843. Thus chill requirements of 'Williams' pears were not met. Because of the inadequate chill accumulation (32% of the chill units NDASH CU or 78% of the total chill portions NDASH CP), no difference was observed in the final budbreak among the treatments, and the budbreak percentage never exceeded 20% for any treatment. Analyzing the budbreak discriminated per type of shoot (vegetative spurs, reproductive spurs and one-year shoots), no significant differences were observed among the treatments except for vegetative buds in experiment 1, where the treatments with mineral oil achieved a higher final budbreak (20%).

Horse flies (Diptera: Tabanidae) cause direct and indirect losses in livestock production and are important vectors of pathogens. The aim of this study was to determine the diversity and seasonality of horse fly species at an experimental farm in Tacuarembó and the diversity of species in different
departments of Uruguay. For 20 months, systematic collections were performed in two different environments at the experimental farm using Nzi and Malaise traps. In addition, nonsystematic collections were performed at farms located in the departments of Paysandú, Tacuarembó and Colonia.
A total of 3,666 horse flies were collected, and 16 species were identified. These species included three species that had not been previously recorded in Uruguay, namely, Dasybasis ornatissima (Brèthes), Dasybasis missionum (Macquart), and Tabanus aff. platensis Brèthes, and a species that had not been
previously taxonomically described (Tabanus sp.1). Among the systematically captured samples, the most abundant species were Tabanus campestris Brèthes, T. aff. platensis and D. missionum, representing 77.6% of the collected specimens. The horse fly season in Tacuarembó started in September and ended in May. No horse flies were caught during winter. Variations in the prevalences of species in the different departments were observed, which indicates the need for new sampling efforts. |
