Insect — Hemiptera

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 : Aphids and phylloxera (Adult (and nymphs resembling the adult))

Scientific name : Daktulosphaira vitifoliae (also Viteus vitifoliae)

Other names : Phylloxera

Small sap-sucking insect related to aphids, native to North America, living on grapevine roots and sometimes on leaves. Its feeding causes swellings on roots and galls on the underside of leaves, gradually weakening Vitis vinifera vines until they die. It caused the great European wine crisis of the late 19th century.

Crops affected : Grapevine (36 varieties)
