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 : Rhynchophorus ferrugineus

Other names : Asian palm weevil

Weevil 2 to 4 cm long, reddish with black spots, native to South-East Asia and now widespread in the Middle East, the Mediterranean and other regions. Its legless larvae tunnel inside the trunk and crown of date palms, coconut palms and ornamental palms. The central fronds dry and collapse, and the palm may die once the growing point is destroyed.

Crops affected : Coconut, Date (Date palm), Ornamental trees and shrubs
