Butterflies of family Papilionidae, generally called the swallowtail butterfly, feeds and lays eggs on the leaves of the Rutaceae family. Phytochemical compounds, called oviposition stimulants, stimulating oviposition are the most important factor for triggering the oviposition behavior. Females perceive oviposition stimulants as tastants through their chemosensilla on the foreleg tarsomere to determine if a plant is suitable for larval feeding. Interestingly, these stimulants show no oviposition activity when assayed as single compounds, and they need to be presented as a mixture for eliciting the oviposition behavior.Here we attempted to elucidate why these compounds need to be presented as a mixture, using electrophysiological observations and oviposition behavioral assays. Our data suggests the firing of all three spikes in the discrete GRNs (taste cells) housed into the sensilla is essential for inducing oviposition behavior in 3 butterfly species of family Papilionidae.

凤蝶科的蝴蝶，通常称为燕尾蝶，在芸香科的叶子上进食和产卵。植物化学物质被称为产卵刺激物，刺激产卵是触发产卵行为的最重要因素。雌性通过前肢跗节上的化学感受器将产卵刺激物视为促味剂，以确定植物是否适合幼虫取食。有趣的是，这些刺激剂没有表现出产卵活性时，作为单一的化合物，它们需要作为一个混合物来诱发产卵行为。我们的数据表明，发射的所有三个尖峰的离散GRNs（味细胞）安置到感器是必不可少的诱导产卵行为的3种蝶科凤蝶。
