(Z)-11-Octadecenyl acetate

(Z)-11-Octadecenyl acetate is a key component of the female sex pheromone isolated from various lepidopteran insects, such as the European corn borer (Ostrinia nubilalis) and the codling moth (Cydia pomonella); in the application of insect pheromones, it is often used as a highly selective attractant, either alone or mixed with other pheromone components (e.g., a small amount of trans isomers) to monitor the field population dynamics of these target pests. It can also be combined with traps for mass trapping, which reduces the use of chemical pesticides while improving the accuracy of pest control.
