  abstract = {{C}losely related species provide an interesting and useful model to understand mate communication diversification. {P}re-mating isolation is the result of selection processes and is achieved by utilization of different sex pheromones, but also by different ecological and life traits such as geographic distribution, host-plant specialization and allochrony of sexual behavior. {H}ere, we report sex pheromone identifications and pre-mating isolation of two closely related species of stemborers: {B}usseola segeta and the yet undescribed {B}usseola nov. sp., developing on different host-plants and in different geographical locations in {K}enya. {GC}-{MS} analyses showed that the two species produced the same pheromone components, but in slight different ratios. {T}he respective synthetic pheromone mixtures tested in the field were attractive for males of each species. {T}he low inter-specific variation in the pheromone mixture would allow possible interbreeding in case of accidental introduction of both species in the same environment. {U}nder laboratory conditions, allochrony of the mating period is total and might prevent interbreeding if confirmed in natural conditions. {T}his point would ensure the reproductive isolation between the two species in case of modifications of ecological factors. {T}his study and the chemical structures of the identified pheromone components clearly demonstrate that these {B}usseola species are closely related although they differ in morphology.},
