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) Beetles (others) (Adult (and nymphs resembling the adult))

Scientific name : Caryedon serratus

Other names : Groundnut borer, Tamarind weevil

Brown bruchid beetle 4 to 7 mm long, found in Africa, Asia, the Americas and Oceania. Its larvae develop inside stored groundnut seeds and the pods of tamarind and several acacias, leaving a round exit hole. It is one of the main insects of stored groundnuts in West Africa.

Crops affected : Peanut, Tamarind
