Q- Which 'Insects cause Trees to form gall (swelling of plant tissue)'?
Answer:
The Larvae of some Wasps belonging to Order Hymenoptera, cause trees to form galls. The wasps lay their eggs in the growing tissues of the tree in the spring. The wasps secrete growth-regulating chemicals that interact with chemicals in the plant to create the abnormal growth. The gall produced provides food for the larvae that live in the gall.
