直接和间接的生态相互作用,环境因素,寄主植物的物候可以塑造螨虫相互作用的方式。这些关系会干扰物种的发生,从而改变植物内群落的结构和稳定性。由于掠食性螨是食草螨的调节者,我们假设这些螨虫可能在与芒果树相关的螨虫物种之间的相互作用网络中占据中心位置,这些物种的发生是由环境变量和寄主植物的物候阶段介导的。我们评估了与单个芒果属植物相关的螨相互作用网络的整体结构,并使用无向贝叶斯网络方法分析了该物种的种间关系。此外,我们观察到螨种群密度与植物物候阶段之间存在相关性。环境变量,例如每月平均气温,月降水量,采用不同采样日期的平均月相对湿度进行相关性分析。螨-植物网络级别的模块化显示出低专业化指数H2=0.073(通才)和高鲁棒性(R=0.93)。网络分析显示,Bdellaueckermanni,acacaciae,在芒果树上发生的螨虫聚集中,塔克雷拉占据了中心位置。环境变量,月平均气温,月降水量与福尔摩沙的发生有关,Cisaberoptuskenyae,木瓜,T.Ornata,还有VilaiaPamithus.我们还观察到植物物候阶段与新胡斯托尼种群密度之间的相关性,O.punicae,刺槐,和V.帕米萨斯。
Direct and indirect ecological interactions, environmental factors, and the phenology of host plants can shape the way mites interact. These relationships interfere with species occurrence and consequently alter the structure and stability of the intraplant community. As predatory mites act as regulators of herbivorous mites, we hypothesized that these mites may occupy a central position in a network of interactions among mite species associated with mango trees, and the occurrence of these species is mediated by environmental variables and the phenological stage of the host plant. We evaluated the global structure of the interaction network of mites associated with individual Mangifera indica plants and analyzed the interspecific relationships of the species using an undirected Bayesian network approach. Additionally, we observed a correlation between mite population density and plant phenological stage. Environmental variables, such as average monthly temperature, monthly precipitation, and average monthly relative humidity at different sampling date were used in the correlation analysis. The modularity at the mite-plant network level showed a low specialization index H2 = 0.073 (generalist) and high robustness (R = 0.93). Network analysis revealed that Amblyseius largoensis, Bdella ueckermanni, Parapronematus acaciae, and Tuckerella ornata occupied central positions in the assembly of mites occurring on mango trees. Environmental variables, average monthly temperature, and monthly precipitation were correlated with the occurrence of Brachytydeus formosa, Cisaberoptus kenyae, Oligonychus punicae, T. ornata, and Vilaia pamithus. We also observed a correlation between the plant phenological stage and population densities of Neoseiulus houstoni, O. punicae, P. acaciae, and V. pamithus.
