  abstract = {{W}hen a promising natural enemy of a key pest exists locally, it is a common practice in biological control ({BC}) to rear and release it for supplementary control in the targeted agroecosystem even though significant knowledge gaps concerning pre/post release may still exist. {I}ncorporating genetic information into {BC} research fills some of these gaps. {H}abrobracon hebetor, a parasitoid of many economically important moths that infest stored and field crops worldwide is commonly used, particularly against the millet head miner ({MHM}), a key pest of millet in {S}ahelian countries. {T}o advance our knowledge on how {H}. hebetor that occurs naturally in open-field cropping systems and grain stores as well as being mass-produced and released for {MHM} control, performs in millet agroecosystems in {N}iger we evaluated its population genetics using two mitochondrial and 21 microsatellite markers. {T}he field samples were genetically more diverse and displayed heterozygote excess. {V}ery few field samples had faced significant recent demographic bottlenecks. {T}he mating system (i.e. nonrandom mating with complementary sex determination) of this species may be the major driver of these findings rather than bottlenecks caused by the small number of individuals released and the scarcity of hosts during the longlasting dry season in {N}iger. {H}. hebetor population structure was represented by several small patches and genetically distinct individuals. {G}ene flow occurred at local and regional scales through human-mediated and natural short-distance dispersal. {T}hese findings highlight the importance of the mating system in the genetic diversity and structure of {H}. hebetor populations, and contribute to our understanding of its reported efficacy against {MHM} in pearl millet fields.},
