ABSTRACT
Sex pheromone analogs have high structural similarity to sex pheromone components. They also play a role in studying many agricultural pests. In our study, (Z, Z, Z)-3,6,9-nonadecadiene (Z3Z6Z9-19Hy) was successfully synthesized, which is an analogue to 1 of 2 sex pheromone components of Ectropis grisescens Warren (Z, Z, Z)-3,6,9-octadecatriene (Z3Z6Z9-18Hy), and it showed potential inhibition in experiments. In the electroantennogram test, Z3Z6Z9-19Hy showed a dose-dependent response, and only measured half the response of Z3Z9-6,7-epo-18Hy. However, the compound significantly reduced positive response of E. grisescens males by up to 70% in the Y-tube olfactometer. Furthermore, in the wind tunnel, it significantly inhibited all types of behavioral responses. The percentage of moths contacting the pheromone odor source was reduced even at the lowest dose tested. In silico study afterward, molecular docking results showed affinity between Z3Z6Z9-19Hy and sensory neuron membrane protein 1. Our study revealed the potential of Z3Z6Z9-19Hy as a sex pheromone inhibitor, which would provide new tools for monitoring and mating disruption of E. grisescens.
