Insect — Coleoptera

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 : Sitona lineatus

Other names : Pea and bean weevil

Small grey-brown weevil 4 to 5 mm long with lengthwise stripes. In spring adults notch the edges of pea and faba bean leaves, leaving very typical semicircular notches; larvae live in the soil and feed on the nitrogen-fixing root nodules.

Crops affected : Fava bean, Pea
