abstract

Phoracantha semipunctata F., a cerambycid beetle introduced into California within the last 10 years, is killing large numbers of eucalyptus trees throughout much of the state. Risk of tree mortality can be reduced through managing tree stress, selection of more resistant tree species and disposal of infested wood. A biological control program to reduce beetle populations through the introduction of egg and larval parasites is currently being implemented. The combination of appropriate tree management and biological control holds promise for protecting these valuable ornamental tree species.
