The increasing demand for safe and sustainably produced food is leading to the development of strategies of pest control alternative to chemicals. One innovative method is Vibrational Mating Disruption (VMD) to disrupt insect communication in plants. VMD was proven effective in preventing mating of the grapevine pest Scaphoideus titanus, vector of flavescence dorée. However, the stress induced by VMD on the target species has the potential to influence other crucial aspects of the insect biology and ethology. Therefore, the goal of this study was to understand side effects of VMD on the flight activity and oviposition of S. titanus. The results of our experiments conducted in the greenhouse showed that in the presence of a receptive female, males fly more if exposed to vibrations than in the silent control but not differently from singles males in silence. Surprisingly, we found that also females subjected to VMD fly more than in the silence. Regarding oviposition, we found that mated females exposed to vibrations and single females (unmated) laid significantly fewer eggs than mated females in silence. In conclusion, this study shows the potential of VMD to interfere, besides with mating, with other important biological aspects of the pest species.
对安全且可持续生产的食品的需求不断增加，促使人们开发替代化学方法的害虫防治策略。一种创新方法是振动交配干扰（VMD），用于扰乱植物中的昆虫通讯。事实证明，VMD在防止葡萄害虫黄斑叶蝉（flavescence dorée的传播媒介）交配方面有效。然而，VMD对目标物种造成的压力有可能影响昆虫生物学和行为学的其他关键方面。因此，本研究的目的是了解VMD对黄斑叶蝉飞行活动和产卵的副作用。我们在温室中进行的实验结果表明，在有可接受雌虫的情况下，与安静对照组相比，暴露于振动中的雄虫飞行次数更多，但与单独处于安静环境中的雄虫没有差异。令人惊讶的是，我们发现遭受VMD处理的雌虫飞行次数也比处于安静环境中的雌虫更多。关于产卵，我们发现暴露于振动中的已交配雌虫和单独的雌虫（未交配）产卵量明显少于处于安静环境中的已交配雌虫。总之，本研究表明VMD除了干扰交配外，还可能干扰害虫物种的其他重要生物学方面。
