RESUMEN.
Los acridios (Orthoptera: Caelifera: Acridoidea) son insectos nativos que habitan pastizales en Uruguay. En ciertas ocasiones incrementan la abundancia exponencialmente, como en los años 1950´ y en 2008/09, causando importantes pérdidas económicas. Este trabajo tuvo como objetivo describir la variación interanual de la abundancia y diversidad de las comunidades que habitan pastizales de la región centro-sur. El seguimiento de las poblaciones se realizó durante cinco temporadas, en sitios de Florida y Durazno. Se estimaron: riqueza acumulada y específica por sitio (S), índices de diversidad de ShannonWeiner (H´), equitatividad de Pielou (J´), similitud cualitativa de Sorensen (Is), constancia de presencia (C), y abundancia total (A), específica absoluta y relativa. A través de las variaciones temporales de dichos descriptores comunitarios se identificaron y caracterizaron períodos de explosión poblacional, transición y equilibrio. En 2009/10 (explosión poblacional) S, A, e Is fueron máximos, J? y H? bajos y Borellia bruneri (Rehn, 1906) fue la más abundante. El período 2010/11-2011/12 (transición), se caracterizó porque J´ e Is fueron intermedias, A y S bajas, y continuó el predominio de B. bruneri. Durante 2012/13 y 2013/14 (equilibrio), se registraron los más altos J´ y H´, y la abundancia relativa de B. bruneri disminuyó significativamente. En este período Scotussa lemniscata (Stål, 1861) fue predominante. Los resultados obtenidos indican que en pastizales de la región centrosur
del Uruguay, el predominio de B. bruneri, la disminución en J´ y el aumento de Is serían indicadores de un período de transición hacia una explosión poblacional.

SUMMARY
Acridians (Orthoptera: Caelifera: Acrididae) are native insects that inhabit Uruguayan grasslands. Occasionally, abundance increases exponentially, as in the 1950' and in 2008/09, causing significant economic losses. This work aimed to describe the variation in the abundance and diversity of the communities that inhabit the grasslands of south-central region. Acridian populations were monitored during five seasons in Florida and Durazno sites. Cumulative and site-specific (S) richness,
Shannon-Weiner (H ?) diversity index, Pielou evenness (J?), qualitative similarity of Sorensen (Is), constance of presence (C), total abundance (A), and absolute and relative specific abundance were estimated. Based on these community descriptors and their temporal variations, we identified and characterized outbreak, transition and non-outbreak periods. In 2009/10 (outbreak) S, A, and Is , were highest, J ? and H? were low, and Borellia bruneri (Rehn, 1906) was the most abundant species.
The 2010/11 -2011/12 period (transition), was characterized by intermediate J? and Is , low A and S, and B. bruneri remained predominant. During 2012/13 and 2013/14 (equilibrium), higher values of J ?and H?, and low values of A, S and Is were recorded, and the relative abundance of B. bruneri decreased significantly. In this period Scotussa lemniscata (Stål, 1861) was the predominant species. These results indicate that in the grasslands of south-central region of Uruguay, the prevalence
of B. bruneri, the decrease in J? and increase in Is , would be indicators of a transition period to an outbreak. MenosRESUMEN.

Abstract:
The objective of the present study was to evaluate the productive performance and grazing behavior of 25 primiparous and 44 multiparous Holstein cows in a pasture-based automatic milking system (AMS) while experiencing heat stress (defined as a temperature-humidity index-THI ? 68). Productive traits were analyzed according to the THI from days 0, -1, -2, and -3 in relation to the milking day, and grazing behaviors (expressed as the % of daily observation time) were related to the average THI only on the day of observation. Milk yield was not associated with the THI on day 0, but a significant linear relationship was found with the THI on the three previous days, decreasing approximately 0.18 kg (primiparous) and 0.40 kg (multiparous) per THI unit increment. In contrast, for multiparous cows only, the milking frequency was positively associated with the THI on the day of evaluation but not on the previous days, increasing 0.01 milking/THI unit increments. Additionally, for each unit of THI increment, cows spent 0.14% more time standing, whereas they exhibited a decrease in grazing, lying, and ruminating behaviors time by 0.30%, 0.04%, and 0.70%, respectively, for both parities. In conclusion, milk loss was related to heat stress conditions from the previous days, but not milking frequency, which increased with the THI of the same milking day. Lower grazing, lying, and ruminating activities and greater standing behavior were observed due to heat stress. © The Author(s) 2022.
