The larvae feed on flower buds, developing berries and, finally and most destructively, on the ripening fruit. Loss of as much as one- third of the vintage has often occurred in areas of Syria, Israel, and Yugoslavia. Infestations up to 75 percent have been observed in the Astrakhan region of and an outbreak in the Touraine section of France in 1913 was so severe that only a few growers were able to save their crops. In France the moth was only of local importance around 1890 but by 1920 it was a serious menace to practically all vineyards in the country. Outbreaks were unusually severe in many districts of central Europe in 1925 and in Germany in 1927. In addition to primary damage to the grapes, the wounds made by L. botrana attract other insects and predispose the fruit to pathogenic fungi. ~.
