在传统的杂草生物防治中，节肢动物的小集合是在目标植物的原生范围内的一个或几个地点进行的，并且通常在广泛的地理范围内引入以抑制已成为入侵植物的植物。在新的范围内，生态不匹配是可能的，使用生物防治剂的成功可能取决于有益的生活史性状的释放后进化。在本研究中，我们测量了一种甲虫（Diorhabda carinulata）的滞育诱导临界日长（50%的种群进入休眠的日长）的演变，这种甲虫（Diorhabda carinulata）在引入北美的7年后从北美的四个地点采集了甲虫种群，发现临界日长呈下降趋势，并在纬度梯度上形成了一个倾斜。临界日长的减少与繁殖活动增加16天相关，从而使柽柳甲虫生活史与物候特征更加吻合。这些结果表明，小轮菊对柽柳的防治效果增强，范围越来越广。
In classical weed biological control, small collections of arthropods are made from one or a few sites in the native range of the target plant and are introduced to suppress the plant where it has become invasive, often across a wide geographic range. Ecological mismatches in the new range are likely, and success using the biocontrol agent may depend on postrelease evolution of beneficial life history traits. In this study, we measure the evolution of critical day length for diapause induction (day length at which 50% of the population enters dormancy), in a beetle (Diorhabda carinulata) introduced into North America from China to control an exotic shrub, Tamarix spp. Beetle populations were sampled from four sites in North America 7 years after introduction, and critical day length was shown to have declined, forming a cline over a latitudinal gradient At one field site, decreased critical day length was correlated with 16 additional days of reproductive activity, resulting in a closer match between beetle life history and the phenology of Tamarix. These findings indicate an enhanced efficacy and an increasingly wider range for D. carinulata in Tamarix control.
