使用摄像机和交流电电子测量系统监测了褐飞虱（Stal）（同翅目：飞虱科）在水稻 Oryzae sativa L. 上的产卵行为。褐飞虱的产卵总是发生在探针刺入植物期间。产卵器穿透后，观察到三种特定的产卵序列；锯切产卵器的插入、在植物中释放卵、以及将产卵器部分或完全从植物中撤回。记录了与这些事件相关的独特波形。根据一系列波形模式，可以确定植物组织内产卵和卵块的数量以及产卵行为的持续时间。波形分析表明褐飞虱产下的卵块平均包含 5.7 个卵。这发生在管心针刺入约 6.4 分钟后的 4.3 分钟，并且该序列在 24 小时内重复多次。在记录后 24 小时内，电和/或系留对产卵的影响似乎可以忽略不计。
Oviposition behavior of Nilaparvata lugens (Stal) (Homoptera: Delphacidae) on rice, Oryzae sativa L., was monitored using a videocamera and an AC (alternating-current) electronic measuring system. Oviposition by N. lugens always took place during stylet penetration into the plant. After penetration of the ovipositor, there were three specific ovipositional sequences observed; sawing insertion of the ovipositor, release of an egg in the plant, and partial or complete withdrawal of the ovipositor from the plant. Distinctive waveforms were recorded in correlating with these events. From a sequence of waveform patterns, it was possible to determine the number of eggs and egg masses laid inside the plant tissue and the duration of oviposition behavior. Waveform analysis revealed that N. lugens laid an egg mass consisting of on average 5.7 eggs. This occurred 4.3 min after a period of about 6.4 min of stylet penetration, and this sequence was repeated several times in 24 h. Electrical and/or tethering effects on oviposition appear to be negligible within 24 h of recording.
