  abstract = {{P}rotapiori trifolii and {P}. fulvipes ({C}oleoptera: {B}rentidae) are major pests in {E}uropean clover seed production. {P}revious studies have reported a high host plant fidelity of these weevils for red and white clover species, respectively, driven by host plant olfactory cues. {G}iven the specific host preferences observed in these weevils, we aimed to elucidate to which extent such selectivity is reflected in their peripheral olfactory systems. {U}sing an electrophysiological approach, we performed the first functional characterisation of olfactory sensory neurons ({OSN}s) in {P}. trifolii to a panel of volatile compounds emitted by red clover plants, and compared the results with the reported {OSN} types of {P}. fulvipes. {N}ineteen {OSN} classes were characterized in {P}. trifolii, with the majority of these neurons responding strongly to common volatiles released by the host plant. {B}ased on response profiles, eight of these {OSN} classes have clear matches to {OSN} classes in {P}. fulvipes. {T}he {OSN} colocalisation patterns and antennal frequency of these classes are similar in the two species. {A}dditionally, the responses of these {OSN}s are generally highly conserved in the two species, with clear response shifts only revealed for two of the {OSN} classes. {T}hese response shifts in combination with additional response dissimilarities for compounds that vary in abundance between red and white clover plants may underlie the species-specific host preferences. {F}urther behavioural and field experiments should focus on these differentially detected compounds to elucidate their potential role in host selection and use in semiochemical-based control of these pests.},
