| Abstract | The univoltine insect, Agonopterix ulicetella, was introduced into Chile from Hawaii and the UK in 1996 and 1997, respectively, for the biological control of gorse, Ulex europaeus. Release strategies to enable this agent to persist on gorse bushes were investigated. Five release sizes: 0, 2, 4, 8, 16 and 32 third-instar larvae, four times replicated, were made on gorse branches enclosed with a fine mesh sleeve. Over two seasons, agent population parameters and damage to the gorse branches were assessed. For A. ulicetella, the critical initial release size was eight larvae. The number of gorse shoots attacked by A. ulicetella was dependent on release size. The 8, 16 and 32 larval density levels resulted in a larger number of attacked shoots than did the lower larval densities. |
