A Royal Society of New Zealand talk taking place on Friday (March 24) will delve into the risks, benefits and challenges of biological control, also known as pest control or pest management.

AgResearch principal scientist and University of Otago honorary professor Barbara Barratt will draw on her expertise to discuss the recent history of biological control and the rise in interest in biosafety aspects.

Barbara says pest management using natural enemies has been used for more than 3,000 years, with Chinese farmers recognising they could reduce the impact of orchard pests by transferring predatory ant nests to their trees. 

More recent biological control has led to “a groundswell of concerns about potential harmful ecological impacts,” Barbara said.

“After a period of intense controversy, it was generally accepted that pre-release risk assessment for biocontrol agents should be a requirement, and many regulatory agencies throughout the world have legislated accordingly.”

Barbara will describe research undertaken to support decisions by the Environmental Protection Authority and the Department of Conservation.

Barbara’s talk, ‘Biological Control: The Risks, Benefits and Challenges’ will take place at 6pm this Friday (March 24) at the Presbyterian Community Centre at 94 Tenby Street.

Entry is $5 for adults and students are free. No bookings necessary.
