(Also known as: Leopard moth sex pheromone; E2Z13-18Ac) |
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.

The commercial production of pheromone attractants and lures involves a sophisticated blend of synthetic chemistry, entomology, and precision engineering. Manufacturers begin by identifying the specific pheromone compounds emitted by target pests, such as sex, aggregation, or alarm pheromones, and then replicate these molecules using chemical synthesis. |
|
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. |
