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

Eurytoma cattleianii (Hymenoptera, Eurvtomidae) from Brazil was under consideration as a potential biological control agent for Psidium cattleianum (strawberry guava). It attacks emerging shoots producing a gall at the base of the shoot. At the end of the growing season the shoot distal to the gall dies, terminating growth of that branch and stunting the plant. The species is confined to the higher elevations (800-1,100 m) of Parana State, Brazil. Its potential as a biocontrol may be limited because researchers have not been able to culture the insect in controlled conditions, and coordinating the availability of insects with plants with flushing shoots at the proper stage of development would be difficult.
