  abstract = {{M}any taxa used in biological control may be composed of several population units reproductively isolated to various degrees. {Y}et, the introductions of non-compatible populations may result in a depression of intended biological control. {C}otesia plutellae has been widely used as a biological control agent of the diamondback moth, {P}lutella xylostella. {H}owever, not all introductions and augmentations were successful. {W}ith the aim to develop markers of compatibility for this species, we studied the reproductive compatibility between five populations ({S}outh {A}frica, {B}enin, {M}artinique, {R}eunion, and {T}aiwan) and analyzed its statistical relationship with three morphological characters (antennae and body length and antennae/body ratio), one molecular character (sequence of a cytochrome b fragment) and the {W}olbachia infection status. {T}his study shows that {C} plutellae populations formed two interbreeding groups. {T}he antenna/body length ratio of females, the ratio between male and female body length, one non-silent base pair substitution observed in cytochrome b sequences, and {W}olbachia infection status differentiate these groups and were all good predictors of reproductive compatibility. {O}ur results suggest also that genetic factors independent from {W}olbachia are needed to fully explain reproductive isolation between {C} plutellae populations. {W}e conclude that {C} plutellae is a single species composed of at least two partially incompatible population aggregates. {D}iagnostic markers were proposed for the prediction of the level of reproductive compatibility between populations which can be used for further biocontrol introductions.
