[R]Biology
- 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.
[R]Life Cycle
- 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.
[R]Damage
Damage caused by the larva to the roots
can be very serious, particularly in young vineyards in Mediterranean
regions.
