Olfaction is generally assumed to be critical for survival because this sense allows animals to detect food and pheromonal cues. Although the ability to sense sex pheromones [1, 2, 3] is likely to be important for insects, the contribution of general odor detection to survival is unknown. We investigated the extent to which the olfactory system confers a survival advantage on Drosophila larvae foraging for food under conditions of limited resources and competition from other larvae.
嗅觉通常被认为对生存至关重要,因为这种感官能让动物检测到食物和信息素线索。虽然感知性信息素的能力[1,2,3]对昆虫可能很重要,但一般气味检测对生存的贡献尚不清楚。我们研究了在资源有限且存在其他幼虫竞争的条件下,嗅觉系统在多大程度上赋予果蝇幼虫觅食时的生存优势。
