- Ajuste de modelo fenológico para predecir el comportamiento de Lobesia botrana (Lepidoptera: Tortricidae) en un viñedo de Mendoza, Argentina Carla Vanina DAGATTI Violeta Cristina BECERRA Biología Touzeau model Pest management Temperature accumulation The variable that most affects the development of Lobesia botrana (Den & Schiff) is temperature, which relationship has been studied using mathematical models, as Touzeau. L. botrana was first identified in 2010 in Mendoza. The aim of this study is to adjust the model of Touzeau to predict the behavior of the moth. The study has been conducted since 2012 in a vineyard cv. Malbec. Pheromone traps have been used. The temperature is recorded by a datalogger sensor. Thermal integral is calculated with Touzeau`s formula using a threshold of 10º C as July 1st of each year. Results indicate that the first flight happened on October 18th the first year and October 20th the second year with 204. 05 ± 10.73 degree days. The second occurred in the first ten days of December in two following seasons with 728.34 ± 41.95 degree days. The third took place during the last fortnight of January in both years with 1329. 08 ± 151.35 degree days. The fourth occurred in mid-February for two seasons with 1721. 84 ± 116.63 degree days. These results are useful to predict the onset of the pest and as a tool to set an alarm system for producers. 2015 artículo científico 1851-7471 https://www.redalyc.org/articulo.oa?id=322043152003 es http://www.redalyc.org/revista.oa?id=3220 Revista de la Sociedad Entomológica Argentina application/pdf Sociedad Entomológica Argentina Revista de la Sociedad Entomológica Argentina (Argentina) Num.3-4 Vol.74
