Status of Eurytoma desantisi as a biocontrol agent for Psidium cattleianum in Hawaii

Eurytoma desantisi (Hymenoptera, Eurvtomidae) causes galls at the base of shoots of strawberry guava (Psidium cattleianum), inhibiting the development of flower buds and eventually causing death to the shoots. The insect is found in Parana State (800-1100m), Brazil, and has been considered as a biocontrol agent for strawberry guava (Psidium cattleianum). Difficulties raising the insect in controlled conditions may limit its potential as a biological control agent. Eurytoma desantisi is species-specific. It attacks the yellow and red fruited forms of strawberry guava, with preference for the red form. The insect's adaptation for higher elevations may be advantageous since Psidium cattleianum has been especially invasive in the higher elevations in Hawaii.
