grape berry moth
Lobesia botrana ([Dennis & Schiffermuller])
European grapevine moth
- Lobesia botrana, the European grapevine moth, is native to Southern Italy. It feeds on berries and berry-like fruits such as grapes, reducing the crop yield and causing the fruits to be more susceptible to fungal infections. L. botrana adults are 0.23-0.31 in. (6-8 mm) long with a wing span ranging from 0.7-0.78 in. (18-20 mm). One characteristic to help in identification is the pattern that is mostly gray colors, with three slightly slanted bands. The caterpillar is up to 0.35 in. (9 mm) long and green or greenish-brown in color.
- Life Cycle
- L. botrana is a typical multivoltine species with facultative diapause. They can have 2-4 generations per growing season varies depending on the latitude, climate and microclimate. The first generation is anthophagous with following generations being carpophagous.
- L. botrana was first described from Austria and is now found throughout Europe, North and West Africa, the Middle East, and Russia. It has more recently been reported in Japan and Chile. In 2009 L. botrana was reported in the United States in California.
- Control Efforts
- Integrated pest management will be the best approach to managing L. botrana. This includes insecticides and sex pheromone-based strategies that disrupt mating. The latter is considered a more environmentally safe management approach.
