Resumo(s)
The European grape berry moth Lobesia botrana Denis & Schiffermüller (Lepidoptera: Tortricidae) is
responsible for direct losses due to the damage cause to the grapes and indirect losses by allowing access to
the grey mould Botrytis cinerea Pers. In some varieties – as Touriga Franca – the attacks are always more
intensive than with other varieties.
In this work, bio-assays have been performed to test the oviposition’s behaviour of L. botrana female.
Three varieties of Vinhos Verdes region – Arinto, Loureiro and Trajadura – and three varieties of Douro
region – Barroca, Touriga Franca, Touriga Nacional – have been tested. Only Touriga Franca presented
significantly difference being more attractive. The bio-assays partially elucidate field observations and
denounce a possible existence of alelochemicals in grapes berries.
