Abstract

Lay Summary Host-plant shifts have contributed significantly to the diversification of phytophagous insects. Combining behavioral experiments with chemical analysis, we show that males of Altica flea beetles use species-specific cuticular hydrocarbons (CHCs) to identify conspecific mates. The profile of CHCs and male mating preference in F1 hybrids are modified by host plant. Our results highlight behavioral divergence due to host-dependent contact sex pheromone is a possible scenario for ecological speciation of herbivorous insects.
