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-mining caterpillar (Larva) Butterflies and moths (Adult (and nymphs resembling the adult))

Scientific name : Acrolepiopsis assectella

Other names : Onion leaf miner

Small brown moth about 8 mm long whose caterpillars attack leek, onion, garlic and chives. The caterpillars mine the leaves and move down towards the heart of the plant, leaving whitish patches, holes and droppings that open the way to rots. It usually has two or three generations a year, with the heaviest damage in late summer.

Crops affected : Garlic, Leek, Onion
