Coccinellida carnivorous beetle feeds on colonies of aphids present on ornamental plants , fruit trees and vegetables , both in greenhouses and in open fields. The adult, which measures around 3 to 5mm, can come in two different liveries: a dark and a red - orange; in both cases there is a stain in the center of each elitra (bipunctata).
This coccinellid is generally used as aphidificant entomopredist on herbaceous, arboreal and shrubby plants. The adults, the third and the fourth larval age are the most voracious stages able to devour a large number of prey a day.
The introduction of ' Antalya bipunctata should be carried out in the presence of substantial infestations, in fact, requiring a large number of prey, is not, therefore, suitable for early launches in the absence of aphids.
Antalya is active with mild temperatures (from March to October) therefore, it is preferable to use it from spring. The development from egg to adult consists of four larval ages and requires just over 20 days with temperatures of about 20-25 ° C.
The adult females lay their eggs in small groupings near the aphidic colonies, the newly born larvae start to feed on prey, first looking for the nearest and smaller ones, then, as they acquire great mobility, they extend their radius of action.
The widespread introduction of adults, active flyers, in cultivated areas is recommended, while larvae are more suitable for launches located in the infestation outbreaks.

Adalia bipunctata controlla:
L’introduzione dell’Adalia bipunctata va effettuata in presenza di infestazioni consistenti, infatti, richiedendo un elevato numero di prede, non risulta, di conseguenza, adatta per lanci anticipati in assenza di afidi.
È consigliata l'introduzione diffusa degli adulti, attivi volatori, in aree coltivate, mentre le larve sono più indicate per lanci localizzati nei focolai di infestazione.
