摘要：

The safety record of weed biocontrol was questioned recently when examples of damage to non-target plants were reported overseas. Until now, systematic investigations of non-target feeding have not been performed in New Zealand. Results of surveys looking for evidence of non-target damage caused by 20 biological control agents released against weeds in New Zealand are presented. Most agents (16) are apparently host-specific. However, two species (Tyria jacobaeae and Phytomyza vitalbae) were recorded attacking native plants, although their attack was very minor and predictable from host-range testing performed prior to release. For two other species, Bruchidius villosus and Cydia succedana, non-target attack was not predicted from host-range testing. Larval feeding by these species was confined to mainly weedy, exotic plants that are closely related to their target plants. The reliability of host-specificity testing and overall safety record of weed biological control in New Zealand are discussed.
