Insect Pests in Eden: Sprays Are Mandatory

The Eden Project

The Eden Project

The Eden Project was designed as a world class visitor destination to celebrate the interdependence of plants and people and to educate people about the need to care for the world that cares for them.

The project site, located in a recently decommissioned china clay quarry near St Austell, Cornwall, UK, is 105 hectares in size and consists of two large enclosed biomes set in gardens (outdoors biome) along with an educational resources building (the core) and a visitor reception building.

With two large indoor biomes covering the humid tropics and warm temperature climates, the outdoor biome with a range of temperate environments, plus several catering facilities, a warehouse and a waste recycling yard, pest management at Eden is very broad with many challenges in all areas.

Despite the procedures put in place for interception, a steady stream of introductions of pest and non-pest invertebrate species has occurred in the RFB.

“Unfortunately, during the early years of the project a number of non-indigenous pest species were introduced into the Rain Forest Biome (RFB) and not successfully eliminated. Currently there are five species that are the subjects of a containment notice issued by DEFRA; banana borer, banana aphid, atratus white fly, coconut mealybug and latin aphid. The containment notice dictates that the Eden Project has to monitor the populations of these pests and maintain pesticide programmes to control their populations.

In January 2002, adults of Tobacco White Fly were detected on leaf samples collected from the RFB. This discovery instigated the placement of an eradication order by DEFRA which initiated the immediate implementation of monitoring and a chemical control programme.

Eradication was achieved after a two year intensive spray programme involving repeated biome-wide sprays using a range of chemicals including buprofezin, thiacloprid, pymetrozine and nicotine.”
