- There is an increasing evidence that populations of ectotherms can diverge genetically in response to different climatic conditions, both within their native range and (in the case of invasive species) in their new range. Here, we test for such divergence in invasive whitefly Bemisia tabaci populations in tropical Colombia, by considering heritable variation within and between populations in survival and fecundity under temperature stress, and by comparing population differences with patterns established from putatively neutral microsatellite markers. We detected significant differences among populations linked to mean temperature (for survival) and temperature variation (for fecundity) in local environments. A QST − FST analysis indicated that phenotypic divergence was often larger than neutral expectations (QST > FST). Particularly, for survival after a sublethal heat shock, this divergence remained linked to the local mean temperature after controlling for neutral divergence. These findings point to rapid adaptation in invasive whitefly likely to contribute to its success as a pest species. Ongoing evolutionary divergence also provides challenges in predicting the likely impact of Bemisia in invaded regions.
- Survival data in response to heat shocks in populations of B. tabaci from Colombian Southwest and CaribbeanHere are the data for survival of B. tabaci after heat shocks performed at two treatments: Basal tolerance (45°C: 45°C/1h and then a recovery at 25°C/1h) and induced treatment (40-45°C: 40-45°C/1h, then 40°C/1h and then a recovery time at 25°C/1h). Survival was measured from groups of 10 adults (males and females). These data were assessed from isofemales of B. tabaci belonging to nine populations: six from the Southwest and three in the Caribbean region in Colombia.Survival after heat shocks in B. tabaci.xlsFecundity data in response to heat shocks in populations of B. tabaci from Colombian Southwest and CaribbeanHere are the data for fecundity of B. tabaci after heat shocks performed at two treatments: Basal tolerance (45°C: 45°C/1h and then a recovery at 25°C/1h) and induced treatment (40-45°C: 40-45°C/1h, then 40°C/1h and then a recovery time at 25°C/1h). Couples (males and females) were lead to mate for seven days and then the number of eggs was count. These data were assessed from isofemales of B. tabaci belonging to nine populations: six from the Southwest and three in the Caribbean region in Colombia.Fecundity after heat shocks in B. tabaci.xlsMicrosatellites data in B. tabaciHere are the data for the molecular weigth of ten microsatellites from B. tabaci. These data were assessed from eight populations: five from the Southwest and three in the Caribbean region in Colombia.
