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 : Scarabaeiform larva (white grub) (Larva) Elateriform larva (wireworm) (Larva) Leaf beetle larva and allies (Larva) Beetles (others) (Adult (and nymphs resembling the adult))

Scientific name : Coleoptera

Other names : flea beetles, leaf beetles

Beetles form the largest order of insects; they are recognised by their hardened forewings (elytra) that cover the abdomen like a case. Both adults and larvae can feed on plants: adults chew leaves, flowers or fruit, while larvae often live in the soil, in stems or in wood. Damage ranges from leaves riddled with small holes (flea beetles) and defoliation (Colorado potato beetle) to eaten roots (white grubs, wireworms) and tunnels in trunks, on potato, cabbages, vegetables, cereals, fruit and forest trees.

Crops affected : Apple tree, Arugula, Cabbage, Chestnut, Corn, Cucumber, Eggplant, Oak, Pine, Potato, Rapeseed (Canola), Squash / Pumpkin, Tomato, Wheat
