Small Encyrtidae hymenoptera that lives as a parasitoid at the expense of cochineal cottons. The parasitoid is used for biological control on grapevines and citrus fruits as well as on ornamental plants in greenhouses.
The adult forms of Anagyrus pseudococci have sexual dimorphism in fact: the female, about 2 mm in size, is characterized by a brown-rust coloring with typical grayish lines on the chest and white antennas whose scape is broad and discoid and almost entirely black as the first two articles of the funiculus.
The male, on the other hand, is smaller in size and black with regular and bristly antennae. The limbs in both sexes are clear. Anagyrus pseudococci is active from spring until autumn and performs several generations a year with cycles of about 3-4 weeks. It lays eggs in the second and third age nymphs and in immature females. Parasitized scale insects can be found a few weeks after the parasitoid is launched, in fact, as a result of the attack, the victims swell and become hard yellow-brown mummies. Adult parasitoids will flicker from a round hole in the mummy.
Its research capacity is very high and also acts at low levels of infestation and can therefore be used for early launches from the end of April-May in the open field.
Anagyrus pseudococci controlla:
La sua capacità di ricerca è molto elevata ed agisce anche a bassi livelli di infestazione potendo così essere utilizzato per i lanci precoci già da fine aprile-maggio in campo aperto.
