Description, Biology, Life Cycle, Damage, Common Names, Images
- This highly polyphagous insect develops in vine, fig, most of the fruit and forest trees, market-garden crops, leguminous plants, Cucurbitaceae and wild Rosaceae.
- Adult: the male flies at twilight. The female lays rapidly after she has come out of the ground. She deposits her eggs in clusters in stake cracks, under the bark of old stumps or in large wounds.
- Larva: penetrates the ground and gnaws the roots and the stem. It buries itself deeply in the ground in summer and in winter and returns to the superficial layers in spring and autumn. It pupates in the ground at the end of winter.
- 1 annual generation.
- The adult emerges from the ground as early as December if climatic conditions are favourable, the maximum emergence occurs in February. Hatching of eggs occurs at intervals from March to May and the larva burrows immediately into the ground.
Damage caused by the larva to the roots can be very serious, particularly in young vineyards in Mediterranean regions.
