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 : Scale insects and mealybugs (Adult (and nymphs resembling the adult))

Scientific name : Saissetia oleae

Other names : Olive black scale

Soft scale with a dark brown domed cover 3 to 5 mm long, bearing an H-shaped ridge on its back. It lives mainly on olive, but also on citrus and ornamental shrubs such as oleander. It produces abundant honeydew on which sooty mould grows, blackening leaves and twigs.

Crops affected : Grapefruit, Lemon tree, Mandarin tree, Olive tree, Orange tree, Ornamental trees and shrubs
