RESUMEN - Frankliniella occidentalis (Pergande) es reportada por primera vez para Uruguay en 1999 y a partir de ese momento comienzan a observarse daños de trips más severos y plateados en nectarinos. Las aplicaciones de insecticidas en nuestro país constituyen una estrategia preventiva y van dirigidas a evitar los daños de trips en nectarinos en el momento de floración y ocasionalmente en precosecha. No existen estudios previos sobre la fluctuación poblacional de trips en nectarinos. Debido a esta falta de información, se hace necesario determinar las principales especies quelos atacan, su variación estacional y los métodos de muestreo más adecuados que permitan cuantificar su incidencia y determinar la necesidad de aplicar medidas de control. Con el objetivo de levantar las restricciones antes mencionadas se planteó el presente trabajo. La determinación de la fluctuación poblacional se realizó mediante golpeo de ramas, trampas adhesivas amarillas y colecta de material vegetal que fue luego procesado en embudo de Berlese.Las especies de trips más abundantes colectadas sobre plantas de nectarinos, fueron Frankliniella occidentalis yThrips tabaci. Frankliniella schultzei fue también colectada pero en forma muy esporádica. Los daños, consistentes en plateados sobre la fruta, se visualizaron en precosecha. No se observó otro tipo de daño que pudiera atribuirse atisanópteros. Las trampas adhesivas amarillas colocadas en la planta permitieron determinar la abundancia y fluctuación poblacional de F. occidentalis. La relación varianza/media dejó de manifiesto que las poblaciones de trips se distribuyen de forma agregada.

ABSTRACT - Frankliniella occidentalis (Pergande) was reported for the first time in Uruguay in 1999 and from this time more severe damage has been observed, like silvering in nectarines. Pesticide to avoid thrips damage in our country area pplied at flowering and occasionally at preharvest. These applications are preventive, without considering the presence or abundance of a particular species, because identification in the field is not possible and there are no simple methods evaluated to determine presence and abundance of different thrips species on crops. There are no previous studies in Uruguay on thrips population dynamics in nectarines. Owing to this lack of information it is necessary to determine the main species attacking nectarines, their seasonal incidence and the best sampling methods to quantify incidence and determine the need for control measures. To left the above mentioned restrictions, the present research was proposed. The fluctuation of populations for different thrips species was studied using branchtapping, yellow sticky traps and collection of fresh material which was then processed in a Berlese funnel. Thripsspecies collected on nectarine trees were Frankliniella occidentalis and Thrips tabaci.Frakliniella schultzei wasalso collected but only sporadically. Damage consisting in silvering on fruit was observed at preharvest. No other kind of damage attributable to thysanopters was observed. The yellow sticky traps put on the trees allowed thequantification of the abundance and populational fluctuations of F. occidentalis. Variance/media relation showedaggregated distribution in thrips populations.

Abstract:
The aim of this study was to evaluate the reproductive impact of a short-term protein supplementation on a long interval prostaglandin-based protocol (two PG injections 15 d apart; PG15) for timed artificial insemination in sheep. During the breeding season, 437 multiparous Merino ewes grazing native pastures (forage allowance of 6 kg of dry matter/100 kg of live weight; crude protein: 10.8%, metabolic energy: 2.1 Mcal/kg of dry matter) were selected. Ewes were allocated, according to body condition score (3.2 ± 0.2) and body weight (40.6 ± 4.9 kg, mean ± SD), to a 2 × 2 factorial design: type of estrus ?spontaneous estrus (SE) or induced with PG15 (PG15)?, and supplementation (yes or no) before insemination (+FF; soybean meal at Days ?10 to ?3; crude protein: 51.9%, metabolic energy: 2.8 Mcal/kg of dry matter; average consumption 0.9% live weight/ewe/day of dry matter). All ewes were cervically artificial inseminated (Day ?2 to ?3 in SE ewes at estrus detection; Day 0 = timed artificial insemination in PG15 ewes). Ovulation rate on Day 7, non-return to service on Day 23, conception, fertility, prolificacy and fecundity on Day 60 were evaluated. Ovulation rate (1.17 ± 0.40 vs. 1.06 ± 0.25), non-return to service at Day 23 (81.7 vs. 64.2%), conception (78.8 vs. 61.5%), fertility (75.2 vs. 61.5%) and fecundity (0.77 vs. 0.62) were higher in ewes from SE than PG15 group (P < 0.05). However, no differences were observed in prolificacy (1.02 ± 0.16 vs. 1.01 ± 0,12) between groups (P > 0.05). Protein supplementation increased ovulation rate (1.30 ± 0.45 vs. 1.17 ± 0.40), prolificacy (1.18 ± 0.39 vs. 1.02 ± 0.16) and fecundity (0.94 vs. 0.77%; P < 0.05), but not non-return to service on Day 23 (83.8 vs. 81.7%), conception (82.9 vs. 78.8%) or fertility (79.1 vs. 75.2%; P > 0.05) in SE group. The supplement feed to PG15 ewes increased ovulation rate (1.35 ± 0.45 vs. 1.06 ± 0.25), prolificacy (1.25 ± 0.43 vs. 1.01 ± 0.12) and fecundity (0.79 vs. 0.62%; P < 0.05) to levels comparable to SE + FF ewes (P > 0.05). The magnitude of the increase in ovulation rate in PG15 was greater than in the SE group (27 vs. 11%; P < 0.05). However, non-return to service on Day 23 (65.1 vs. 64.2%), conception (63.3 vs 61.5%), and fertility rate (63.3 vs. 61.5%; P < 0.05) remained similar in PG15 supplemented or not supplemented ewes. In conclusion, a short-term protein supplementation before cervical time artificial insemination improved the reproductive performance of ewes synchronized with the PG15 protocol to levels comparable to the SE group MenosAbstract:
