Forecasting the flight activity of Lobesia botrana (Denis & Schiffermüller) (Lepidoptera, Tortricidae) in Southwestern Spain

Abstract

This study aimed at elaborating a forecasting tool of the phenology of the serious pest Lobesia botrana in Southwestern Spanish vineyards, by analysing data on male catches in sex pheromone traps recorded over a 12‐year period. Our data confirmed the minor importance of the first generation which appears during flowering time, both in terms of male trap catches and damage of L. botrana to the inflorescences. Therefore, data related to the first flight were not further processed, although they were considered for the computation of degree‐days of the following generations. The outcome of the elaboration of temperature accumulations and data on male captures for the second and third flights was a statistically acceptable linear behaviour obtained by properly transforming the variables. The models established proved to be efficient and may represent a useful tool to improve the efficacy of integrated pest management strategies targeting L. botrana in the studied region.

Effects of grapevine bunch exposure to sunlight on berry surface temperature and Lobesia botrana (Lepidoptera: Tortricidae) egg laying, hatching and larval settlement

“…The differences between berry and air temperatures should be considered in L. botrana phenological models that are based on daily mean air temperature (Milonas et al ., ; Moravie et al ., ; Gallardo et al ., ; Martín‐Vertedor et al ., ; Amo‐Salas et al ., ; Svobodová et al ., ; Gilioli et al ., ; Moshtaghi Maleki et al ., ). According to the results of the present study, berry temperatures may vary as a result of both row orientation and row side.…”

Relationships among male Coleophora deauratella (Lepidoptera: Coleophoridae) pheromone‐baited trap capture, larval abundance, damage and flight phenology

“…The objective of a phenological model is to predict the time of appearance of specific insect life stages to improve the timing of biological, chemical or cultural control techniques (Hardman, ), which is often used in conjunction with a risk assessment model. Phenological models based on pheromone‐baited trap capture are used to time specific life‐stage sampling and application of control measures for a variety of lepidopteran pests of managed ecosystems, including Cydia pomonella (Tortricidae) (Glen & Brain, ), Podesesia syringae (Sessiidae) (Potter & Timmons, ), Grapholita molesta (Tortricidae) (Rice et al , ), Chilo paratellus (Pyralidae) (Unnithan & Saxena, ), Lymantria dispar (Lymantriidae) (Régnière & Sharov, ), Lobesia botrana (Tortricidae) (Gallardo et al , ) and Acrobasis nuxvorella (Pyralidae) (Knutson & Muegge, ).…”

Prospective analysis of the invasive potential of the European grapevine moth Lobesia botrana (Den. & Schiff.) in California

“…In Europe, a variety of phenological models have been developed for decision support to forecast the flight of adult moths in the different generations with the aim of improving the timing of insecticide applications and other control tactics (Gabel & Mocko, 1984; Baumgärtner & Baronio, 1988; Caffarelli & Vita, 1988; Del Tío et al , 2001; Milonas et al , 2001; Moraviea et al , 2006; Gallardo et al , 2009). Age‐structured phenology models for L. botrana , based on a discrete time (Schmidt et al , 2003) and time‐invariant distributed maturation time model (Vansickle, 1977; Briolini et al , 1997; Severini et al , 2005), have also been developed.…”
