This study determines the prevalence of shea butter tree attack by the African mistletoe and stem borers, explores statistical relationship between prevalence, land use and tree morphological traits. In a the Bohicon shea parklands in Benin, a total of 258 shea butter trees was examined and measured in ten inventory plots in fallows, ten inventories plot in savannah, and ten inventory plots in cropped fields (Agroforestry systems). The classic inference was used to estimate the prevalence of shea trees attacks and Generalized Linear Models (GLMs) of the Binomial and Beta families were used, respectively, to model the relationship between the morphological traits and the attack risk, and the relationship between the land uses and the prevalence. The overall prevalence of pest attack in shea butter trees was 28.7% (CI = 23.3-34.7%), with a prevalence of African mistletoe of 24.8% (CI = 19.7-30.5%) and stem borers had attacked 6.2% (CI = 3.6-9.9%). These prevalence rates are lower than what has been reported from other sites before.
本研究确定了非洲槲寄生和蛀干害虫对乳木果油树的侵害率，探讨了侵害率、土地利用和树木形态特征之间的统计关系。在贝宁的博希孔乳木果油树公园，在休耕地的10个清查地块、稀树草原的10个清查地块和农田（农林业系统）的10个清查地块中，总共检查并测量了258棵乳木果油树。使用经典推断法估计乳木果油树的侵害率，并分别使用二项式和贝塔族的广义线性模型（GLM）来模拟形态特征与侵害风险之间的关系，以及土地利用与侵害率之间的关系。乳木果油树遭受害虫侵害的总体发生率为28.7%（置信区间=23.3-34.7%），其中非洲槲寄生的侵害率为24.8%（置信区间=19.7-30.5%），蛀干害虫的侵害率为6.2%（置信区间=3.6-9.9%）。这些发生率低于之前其他地点的报告。
