Explore the world of aphids in this documentary from 1951. These minuscule insects wield immense power, impacting apple trees worldwide. In this film, we look into the life cycle of the Green Apple Aphid, a common and destructive pest found wherever apple trees thrive. From egg-laying in autumn to nymphs emerging during spring’s “bud burst" and relentlessly feeding on tender growth. As they pierce tissues and suck sap, they leave their mark on leaves, causing curling and damage. But aphids’ influence extends beyond feeding.
