摘要

桉树(Eucalyptus spp., mirtacae)以其显著的再生能力而著称,使其成为恢复退化地区和重新造林的宝贵工具。尽管桉树起源于澳大利亚,但它对巴西的热带气候表现出了显著的适应性,为该国的木材生产力做出了贡献。然而,桉树的广泛单一栽培会增加害虫的发病率,从而对林业部门构成重大挑战,林业部门遭受高达30%的生产损失。本研究对巴西东南部450个桉树林分9年间11种害虫的发生情况进行了分析。我们使用循环均匀性分析和零膨胀模型将害虫发生与特定年份和气候变化联系起来。研究发现,这些物种在年内普遍存在孤立的发生高峰,至少有5种物种的发生增加与温度或降水有关。研究结果强调了害虫对气候条件的敏感性,表明了管理策略对确保桉树人工林的可持续性和生产力的重要性。通过了解这些变量如何与昆虫种群相互作用,我们可以制定更有效的管理策略,有助于桉树人工林的可持续性和生产力,减少侵略性的环境实践。

The Effect of Climatic Conditions on the Seasonality of Pest Insect Populations in Eucalyptus Plantations in the Neotropics.

Eucalyptus (Eucalyptus spp., Mirtaceae) stands out for its remarkable regeneration capacity, making it a valuable tool for recovering degraded areas and for reforestation. Despite its Australian origins, eucalyptus has shown remarkable adaptation to the Brazilian tropical climate, contributing to the wood productivity of the country. However, the extensive monoculture of eucalyptus can increase pest incidence, thus being a significant challenge for the forestry sector, which suffers production losses of up to 30%. We analyzed the occurrence of 11 pest insect species in 450 eucalyptus stands over 9 years in the southeastern region of Brazil in our study. We related pest occurrences to specific year periods and climatic variations using circular uniformity analysis and zero-inflated models. We found that the species generally had isolated peaks of occurrence during the year and that the increase in the occurrence of at least five species was related to temperature or precipitation. The results highlight the sensitivity of pests to climatic conditions, showing the importance of management strategies to ensure the sustainability and productivity of eucalyptus plantations. We can develop more effective management strategies by understanding how these variables interact with insect populations, contributing to the sustainability and productivity of eucalyptus plantations with less aggressive environmental practices.
