Reproductive isolation and differentiation between five populations of Cotesia plutellae (Hymenoptera: Braconidae), parasitoid of Plutella xylostella (Lepidoptera: Plutellidae)



Reproductive isolation and differentiation between five populations of Cotesia plutellae (Hymenoptera: Braconidae), parasitoid of Plutella xylostella (Lepidoptera: Plutellidae)



Biological Control 36(2): 171-182



Many taxa used in biological control may be composed of several population units reproductively isolated to various degrees. Yet, the introductions of non-compatible populations may result in a depression of intended biological control. Cotesia plutellae has been widely used as a biological control agent of the diamondback moth, Plutella xylostella. However, not all introductions and augmentations were successful. With the aim to develop markers of compatibility for this species, we studied the reproductive compatibility between five populations (South Africa, Benin, Martinique, Reunion, and Taiwan) 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 Wolbachia infection status. This study shows that C. plutellae populations formed two interbreeding groups. The 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 Wolbachia infection status differentiate these groups and were all good predictors of reproductive compatibility. Our results suggest also that genetic factors independent from Wolbachia are needed to fully explain reproductive isolation between C. plutellae populations. We conclude that C. plutellae is a single species composed of at least two partially incompatible population aggregates. Diagnostic markers were proposed for the prediction of the level of reproductive compatibility between populations which can be used for further biocontrol introductions.
