Orientational response of Spodoptera frugiperda (J.E. Smith) to linalool oxide
It has become a trend to improve the efficiency of insect sex pheromone trapping by searching for related plant volatiles. In this study, we use the electroantennography (EAG) and Y-tube to study the orientational responses of Spodoptera frugiperda to linalool oxide. The result showed that both male and female moths had an electrophysiological response to linalool oxide. The female moth showed the highest electrophysiology response value (0.40 mV±0.051mV) to 1 μg/μL linalool oxide, which was significantly higher than that of male moth. The behavioral test showed the female moths had a significant orientation to 1 μg/μL linalool oxide, while male moths had a significant repellency to 10 μg/μL linalool oxide. This study provides a basis for the development of effective plant attractants of S. frugiperda.
