Egg-laying decisions based on olfactory cues enhance ofspring ftness in Stomoxys calcitrans L. (Diptera: Muscidae)

Abstract:

Selection of oviposition substrate is critical in holometabolous insects. Female stable fies, Stomoxys calcitrans, locate and select vertebrate herbivore dung in which they lay their eggs. However, the preference for vertebrate herbivore dung by S. calcitrans females, its ftness consequences for ofspring,and the semiochemicals used to locate and select oviposition substrates remain unclear. Using oviposition choice tests and life table bioassays we found that gravid female S. calcitrans prefer to oviposit on donkey and sheep dung, which also improves the performance of their ofspring. GC-MS analysis followed by random forest classifcation identifed β-citronellene and carvone as the most important predictive volatile organic compounds of donkey and sheep dung, respectively. In multiple choice oviposition bioassays, S.calcitrans laid more eggs in wet sand containing β-citronellene and carvone than in other treatments. The attractiveness of these compounds was confrmed in a feld trial, with traps baited with β-citronellene and carvone catching more S. calcitrans. We conclude that gravid female S. calcitrans use semiochemical cues to choose oviposition substrates that maximise ofspring ftness
