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) Beetles (others) (Adult (and nymphs resembling the adult))

Scientific name : Bruchus pisorum

Other names : Pea beetle

Small beetle about 5 mm long, grey with pale markings, whose larvae develop inside pea seeds. The female lays eggs on young pods and the larva bores into the seed, which ends up hollowed with a round exit hole. Unlike the bean weevil, it does not breed in stored grain.

Crops affected : Pea
