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 : Legless larva with a head (weevils, seed beetles, bark beetles, wasps) (Larva) Weevils (Adult (and nymphs resembling the adult))

Scientific name : Anthonomus rubi

Other names : Strawberry bud weevil

Small black weevil 2 to 4 mm long. The female lays an egg in a strawberry or raspberry flower bud and then partly severs the stalk, so the bud wilts and hangs or drops. The larva develops inside the bud; there is one generation a year.

Crops affected : Strawberry
