Abstract

MATEUS, Helena et al. The impact of Jasmine Moth Palpitavitrealis (Rossi) in different olive cultivars in Cova da Beira. Rev. de Ciências Agrárias [online]. 2012, vol.35, n.2, pp.205-209. ISSN 0871-018X.

The attacks of jasmine moth were monitored in three olive cultivars, ‘Arbequina’, ‘Cobrançosa’ and ‘Galega Vulgar’,in a five years old olive grove and also in a plot of‘Galega Vulgar’ one year old near Belmonte. The observations were carried out in 2000, from April 5 to November 7 and the first symptoms were observed on July 7. ‘Cobrançosa’ was significantly less attacked throughout the observation period and no significant differences were detected between the remaining. In order to explain thesedifferences, leaf thickness of the different cultivars were compared by histological cuts but no differences were detected. No other differences regarding the presence and abundance of trichomes were found.

Keywords : ‘Arbequina’; ‘Cobrançosa’; ‘Galega Vulgar’; Oleaeuropaea; Palpita vitrealis.
