Odinadiplosis amygdali

Odinadiplosis amygdali (Anagnostopoulos)

Common name: Almond bud gall midge.

Systematic position: Insecta, Holometabola, Diptera, Nematocera, Cecidomyiidae.

Distribution: Turkey, Lebanon and Greece.

Morphology: Adults blackish, with a brown thorax, about 2-2.5 mm long, legs brownish. Antennae with 14 segments. Larva about 2 mm in length, yellow-white, without an obvious spatula.

Host plant: Almond.

Life history: Odinadiplosis amygdali is univoltine. In early spring the female places its eggs in the host’s buds. The development of the emerging larva causes the infested bud to produce flower-like galls that increase in size as the larvae grow. The fully- grown larvae spend the winter in diapause inside the galls on almond twigs, emerging in spring.

Economic importance: This midge is a serious pest of almonds in Turkey and Greece, preferring and severely damaging its early cultivars. Infestation levels may come to 30-54%.


Horticultural method: Removal and destruction of the infested twigs that carry the galls.

Biological control: Several hymenopteorus parasitoids attack the pest in Turkey, and are considered to be its the main mortality factors. These include Synopeas talhouki (Platygastridae) and Baryscapus oophagus (Otten) (Eulophidae).
