  abstract = {{I}n mosquitoes, the maternally inherited bacterial {W}olbachia induce a form of embryonic lethality called cytoplasmic incompatibility ({CI}). {T}his property can be used to reduce the density of mosquito field populations through inundative releases of incompatible males in order to sterilize females ({I}ncompatible {I}nsect {T}echnique, or {IIT}, strategy). {W}e have previously constructed the {LR}[w{P}ip({I}s)] line representing a good candidate for controlling field populations of the {C}ulex quinquefasciatus mosquito in the islands of the south-western {I}ndian {O}cean. {T}he main purpose of the present study was to fill the gap between laboratory experiments and field implementation, i.e. assessing mating competitiveness of these incompatible males under semi-field conditions. {I}n a first set of experiments, we analyzed crossing relationships between {LR}[w{P}ip({I}s)] males and {L}a {R}eunion field females collected as larvae in 19 distinct localities throughout the island. {T}his investigation revealed total embryonic mortality, confirming the strong sterilizing capacity of {LR}[w{P}ip({I}s)] males. {S}ubsequently, mating competitiveness of {LR}[w{P}ip({I}s)] males was assessed under semi-field conditions in the presence of field males and females from {L}a {R}eunion. {C}onfrontations were carried out in {A}pril and {D}ecember using different ratios of {LR}[w{P}ip({I}s)] to field males. {T}he results indicated that the {LR}[w{P}ip({I}s)] males successfully compete with field males in mating with field females, displaying even higher competitiveness than field males in {A}pril. {O}ur results support the implementation of small-scale field tests in order to assess the feasibility of {IIT} against {C}x. quinquefasciatus in the islands of southwestern {I}ndian {O}cean where this mosquito species is a proven competent vector for human pathogens.},
