为了解黑胸叶蝉的遗传结构和扩散动态。对352个番茄晚疫病菌群体的10个微卫星座位进行了多位点基因型分析。2002年10月，在11个农村社区的21所房屋中收集了infestans。在群落和家庭复合水平上分析了遗传结构。分析表明，病媒控制行为影响了T. infestans种群。持续病媒控制下的社区（核心区）的昆虫种群高度结构化，相邻房屋化合物之间的遗传分化显着。相比之下，从社区与零星的病媒控制行动的错误的人口更均匀，缺乏明确的遗传簇。种群对之间的遗传分化不符合微地理水平上的距离隔离模型。飞行或步行的错误传播的证据一致的社区内和社区之间，传播是女性更偏向于在核心区和结果表明，房屋收到移民来自一个以上的来源。假定的来源和再侵染的机制进行了说明。这些数据可用于设计改进的病媒控制策略
To gain an understanding of the genetic structure and dispersal dynamics of T. infestans populations, we analyzed the multilocus genotype of 10 microsatellite loci for 352 T. infestans collected in 21 houses of 11 rural communities in October 2002. Genetic structure was analyzed at the community and house compound levels. Analysis revealed that vector control actions affected the genetic structure of T. infestans populations. Bug populations from communities under sustained vector control (core area) were highly structured and genetic differentiation between neighboring house compounds was significant. In contrast, bug populations from communities with sporadic vector control actions were more homogeneous and lacked defined genetic clusters. Genetic differentiation between population pairs did not fit a model of isolation by distance at the microgeographical level. Evidence consistent with flight or walking bug dispersal was detected within and among communities, dispersal was more female-biased in the core area and results suggested that houses received immigrants from more than one source. Putative sources and mechanisms of re-infestation are described. These data may be use to design improved vector control strategies
