  abstract = {{T}setse flies ({D}iptera: {G}lossinidae) are the cyclical vectors of human and animal trypanosomes. {T}his viviparous insect develops and produces a single larva at 10-day intervals deposited in specific sites. {I}n some species aggregation of larvae has been shown and seems to be mediated by both physical factors and volatile semiochemicals of larval origin. {I}n this context, this study aims to identify chemicals emitted during the pupariation process in {G}lossina palpalis gambiensis. {V}olatile {O}rganic {C}ompounds ({VOC}s) emitted by larvae were identified using static headspace solid-phase microextraction and gas-chromatography mass-spectrometry ({GC}-{MS}) analysis. {E}lectrophysiology and behavioural assays were performed on gravid females to confirm {VOC}s behavioural activity and attractiveness. {GC}-{MS} results revealed ten chemicals emitted during the pupariation process of {G}. p. gambiensis larvae. {A}mong these chemicals, gravid females were shown to detect nine of them during coupled gas chromatography - electroantennographic detection tests. {B}ehavioural assays highlighted two compounds were as attractive as pupae and one compound and a blend of four compounds were more attractive than pupae. {A}lthough the larval origin of some of them needs to be confirmed as they may also likely produced by micro-organisms, these compounds induced significant behavioural responses in the laboratory. {F}urther experiments have to explore the biological activity and competitiveness of these compounds in the field. {T}his work opens interesting opportunities for behavioural manipulation and control of tsetse flies.},
