Abstract
Compound 1080 is widely used in New Zealand for the control of wild animals. The tendency of 1080 to poison non-target birds and mammals is recognised, but its effects on invertebrates have gone mostly unnoticed. At least 9 invertebrate orders are prone to 1080 poisoning. Invertebrates have been observed eating baits, and their habitats are contaminated by residues leaching from baits, and from animal by-products and carcasses. Poisoned insects provide a means of secondary poisoning for insectivores. Therefore, 1080 should not be used where susceptible invertebrate species or rare insectivores are found.
