Description

Trichogrammatiodea cryptophlebiae are small (0.2 – 1.5 mm) with a yellow/brown body color. The BioTrichogramma adult female lives up to 10 days in optimal conditions and lays eggs inside a fresh FCM egg. From this egg a larva hatches, which starts feeding on the FCM egg and causes the egg to change from yellow to black in color. BioTrichogramma have a very short life cycle, compared to its host. The total development from egg to adult takes about 8 days in summer time.
