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 : Leaf beetle larva and allies (Larva) Beetles (others) (Adult (and nymphs resembling the adult))

Scientific name : Brassicogethes aeneus

Other names : Rape blossom beetle

Small black beetle with a metallic green sheen, about 2.5 mm long. In spring adults arrive in oilseed rape and other brassicas and bite into closed flower buds to reach the pollen; damaged buds wither and drop. Once flowers are open they feed on pollen without harming them; larvae develop in the flowers.

Crops affected : Mustard, Rapeseed (Canola)
