背景:许多昆虫群利用基质传播的振动进行种内交流。这种特性使它们成为探索使用振动作为害虫控制工具的合适模型,以替代化学品的使用。详细了解物种交流是选择最佳信号使用的先决条件。这项研究探索了使用基质传播的振动来控制棕色的臭虫(BMSB)的害虫,HalyomorphahalysStál(异翅目:五翅目)。为此,我们首先确定了最能引起男性反应的频谱和时间特征.用模拟天然雌性呼叫信号的人工信号进行生物测定。第二,我们利用所获得的知识,使用木制定制的T支架,在单选和双选生物测定中合成具有不同吸引力的新信号。
结果:这项研究的结果表明,男性被高振幅范围的女性信号所吸引,特别是从100μms-1的阈值开始,高脉冲重复时间(1s)和对应于第一谐波(76Hz)的频率峰值。这导致了一个“最佳”信号,用于吸引男性,而T竞技场的选择测试表明,该信号会引发搜索行为,并将BMSB雄性吸引到刺激点。
结论:我们确认使用振动信号作为雄性BMSB行为操纵的强大工具,并建议其可能用于开发田间诱捕器和进一步管理该害虫。©2021作者害虫管理科学由JohnWiley&SonsLtd代表化学工业学会出版。
BACKGROUND: Many groups of insects utilize substrate-borne vibrations for intraspecific communication. This characteristic makes them a suitable model for exploring the use of vibrations as a tool for pest control as an alternative to the use of chemicals. Detailed knowledge of species communication is a prerequisite to select the best signals to use. This study explored the use of substrate-borne vibrations for pest control of the brown marmorated stink bug (BMSB), Halyomorpha halys Stål (Heteroptera: Pentatomidae). For this purpose, we first identified the spectral and temporal characteristics that best elicit male responsiveness. Bioassays were conducted with artificial signals that mimicked the natural female calling signal. Second, we used the acquired knowledge to synthesize new signals endowed with different degrees of attractiveness in single- and two-choice bioassays using a wooden custom-made T stand.
RESULTS: The results from this study showed that males were attracted to female signals along a high range of amplitudes, especially starting from a threshold of 100 μm s-1 , a high pulse repetition time (1 s) and frequency peak corresponding to the first harmonic (76 Hz). This resulted in an \"optimal\" signal for use to attract males, while the choice test in the T arena showed that this signal elicits searching behavior and attracts BMSB males towards a stimulation point.
CONCLUSIONS: We confirm the use of vibrational signals as a strong tool for behavioral manipulation of male BMSB and suggest its possible use in the development of field traps and further management of this pest. © 2021 The Authors.
