What is an opportunist?

An "opportunist" is a population (fungi, bacteria, insects…) that takes advantage of a favourable environment to settle in, multiply and feed on it. It often develops when the natural defences of the affected organism are weakened — for genetic reasons or linked to context (water stress, deficiencies, nutritional imbalances, overcrowding…). This is typically the case in monocultures, where a single host plant, uniform and present in large numbers, offers ideal ground for it to spread.

Identification key : Maggot (fly larva) (Larva) Flies (brachyceran Diptera) (Adult (and nymphs resembling the adult))

Scientific name : Drosophila suzukii

Other names : Drosophila suzukii

Small fly of Asian origin, 2 to 3 mm long, whose male has a dark spot at the tip of each wing; it reached Europe and the Americas around 2008. Unlike other vinegar flies, the female has a serrated ovipositor allowing it to lay eggs in healthy, ripening fruit. Larvae develop inside strawberries, cherries, raspberries, grapes, plums and figs, which collapse and rot quickly.

Crops affected : Fig, Grapevine (5 varieties), Peach tree, Plum tree, Strawberry
