  abstract = {{T}he potential effect of population outbreaks on within and between genetic variation of populations in pest species has rarely been assessed. {I}n this study, we compare patterns of genetic variation in different sets of historically frequently outbreaking and rarely outbreaking populations of an agricultural pest of major importance, the migratory locust, {L}ocusta migratoria. {W}e analyse genetic variation within and between 24 populations at 14 microsatellites in {W}estern {E}urope, where only ancient and low-intensity outbreaks have been reported (non-outbreaking populations), and in {M}adagascar and {N}orthern {C}hina, where frequent and intense outbreak events have been recorded over the last century (outbreaking populations). {O}ur comparative survey shows that (i) the long-term effective population size is similar in outbreaking and non-outbreaking populations, as evidenced by similar estimates of genetic diversity, and (ii) gene flow is substantially larger among outbreaking populations than among non-outbreaking populations, as evidenced by a fourfold to 30-fold difference in {F}-{ST} values. {W}e discuss the implications for population dynamics and the consequences for management strategies of the observed patterns of genetic variation in {L}. migratoria populations with contrasting historical outbreak frequency and extent.},
