(Also known as: Boll weevil sex pheromone; grandisol; luretape) |
The following alerts are based on the data in the tables below. An absence of an alert does not imply the substance has no implications for human health, biodiversity or the environment but just that we do not have the data to form a judgement. These hazard alerts do not take account of usage patterns or exposure, thus do not represent risk.

Grandlure refers to a group of male aggression heromones. Grandlure I & II are used mainly and Grandlure III & IV are used in less quantities. Grandlure is used as an attractant and lure for the pine processionary moth and other pests |

Grandlure is commercially produced through a carefully controlled chemical synthesis that replicates the natural blend of four pheromone components: Grandlure I, II, III, and IV. The process involves the stereoselective synthesis of key molecules like grandisol and trans-bicyclo[3.3.0]octane derivatives, which are then blended in precise ratios to mimic the pheromone. Production typically takes place in specialised facilities equipped for low-temperature reactions, high-vacuum distillation, and batch polymerisation to ensure purity and stability. |
|
While exact CO₂e values are not published for specific pheromones, some general information is available. The PHERA reported that biotechnological production (e.g. yeast fermentation) of pheromones can reduce GHG emissions by up to 90% compared to traditional chemical synthesis and GHG emissions are typically in the 5 to 10 kg CO₂e per kg of pheromone produced. Other sources suggest that small scale pheromone synthesis typically has emissions in the range 1 – 3 kg CO₂e per kg of pheromone produced. |
