Abstract:
Bactrocera dorsalis Hendel is a highly invasive horticultural pest that is of major economic importance worldwide. In Burkina Faso, it is one of the main insect pests that affects the production and exportation of mangos. Understanding the biology and the genetic dynamics of this insect pest provides crucial information for the development of effective control measures. The aim of this study was to understand the distribution, diversity, and genetic structure of B. dorsalis in Burkina Faso. Male flies were collected transversally in Burkina Faso and analyzed by PCR using 10 microsatellite markers. The results showed an abundance of B. dorsalis varying from 87 to 2986 flies per trap per day at the different sampling sites. The genetic diversity was high at all sites, with an average Shannon\'s Information Index (I) of 0.72 per site. The gene flow was high between study populations and ranged from 10.62 to 27.53 migrants. Bayesian admixture analysis showed no evidence of structure, while Discriminant Analysis of Principal Components identified three weakly separated clusters in the population of B. dorsalis in Burkina Faso. The results of this study could be used to optimize the effectiveness of current control interventions and to guide the implementation of new, innovative, and sustainable strategies.
摘要:
dorsalisHendel是一种高度入侵的园艺害虫,在全球范围内具有重要的经济意义。在布基纳法索,是影响芒果生产和出口的主要害虫之一。了解这种害虫的生物学和遗传动力学为制定有效的控制措施提供了重要信息。这项研究的目的是了解分布,多样性,和布基纳法索的背芽孢杆菌的遗传结构。在布基纳法索横向收集雄蝇,并使用10个微卫星标记通过PCR进行分析。结果表明,在不同的采样点,每天每个陷阱的背芽孢杆菌数量从87到2986只不等。所有地点的遗传多样性都很高,每个网站的平均香农信息指数(I)为0.72。研究人群之间的基因流量很高,从10.62到27.53移民不等。贝叶斯混合分析显示没有结构的证据,而主成分的判别分析确定了布基纳法索的B.dorsalis种群中的三个弱分离簇。本研究结果可用于优化当前控制干预措施的有效性,创新,和可持续战略。
