Features of SWD (Drosophila suzukii) ovipositor (left) vs non-suzukii ovpositor (right).
Spotted Wing Drosophila (Drosophila suzukii) has an ovipositor that enables it to pierce the skin of healthy fruit still attached to the plant. Drosophila suzukii ovipositor (left): Spines black – color intensity increases sclerotization or hardness. Largest spin located at the tip of ovipositor; punctures the skin of the fruit, allowing insertion of the ovipositor. Non-suzukii ovipositor: Blunt tip of ovipositor. Spines not blackened – less hardened or sclerotized. Cannot pierce skin of healthy fruit.
