概括
斑点灯 (Lycorma delicatula) 伤害树木,但只减少了宾夕法尼亚州的天堂树 (Ailanthus altissima) 的生长. 系统性杀虫剂有助于减轻对Ailanthus altissima的这种影响.
科学领域:
- 生态生态学 生态生态学
- 昆虫学 昆虫学是一门学科.
- 林业林业 林业 林业 林业
背景情况:
- 斑点灯 (Lycorma delicatula) 是一种入侵性植物食昆虫,原产于中国,于2014年首次在宾夕法尼亚州被发现.
- 这种昆虫对农业,装饰,苗圃和木材行业构成重大威胁,原因是检疫限制和植物直接影响.
- 食北美树种的Lycorma delicatula长期影响仍未得到充分研究.
研究的目的:
- 量化Lycorma delicatula养对宾夕法尼亚州四种关键树木物种年增长的影响.
- 评估系统性杀虫剂在缓解Lycorma delicatula对树木生长的影响方面的有效性.
主要方法:
- 采用了使用不同Lycorma delicatula感染水平的树木树芯的 dendrochronological 方法.
- 分析了四种树种:艾兰修斯 (Ailanthus altissima),黑 (Juglans nigra),郁金香 (Liriodendron tulipifera) 和红 (Acer rubrum).这些树种的生长方式是不同的.
- 对树木进行了评估,包括有系统杀虫剂控制和没有系统杀虫剂控制.
主要成果:
- 食Lycorma delicatula与每年增长的减少有关,特别是在Ailanthus altissima中.
- 在其他测试树种 (Juglans nigra,Liriodendron tulipifera,Acer rubrum) 中,没有观察到对年增长的显著影响.
- 系统性杀虫剂似乎可以减轻Lycorma delicatula对Ailanthus altissima的负面生长影响.
结论:
- 艾兰修斯高特别容易受到Lycorma delicatula感染的增长抑制作用.
- 其他常见的宾夕法尼亚树种对Lycorma delicatula的养有弹性,至少在年增长方面.
- 系统性杀虫剂提供了一种潜在的管理策略,以保护像Ailanthus altissima这样的脆弱树种免受侵入性昆虫的伤害.

Threats to Biodiversity
22.3K
There have been five major extinction events throughout geological history, resulting in the elimination of biodiversity, followed by a rebound of species that adapted to the new conditions. In the current geological epoch, the Holocene, there is a sixth extinction event in progress. This mass extinction has been attributed to human activities and is thus provisionally called the Anthropocene. In 2019 the human population reached 7.7 billion people and is projected to comprise 10 billion by...

Predator-Prey Interactions
16.2K
Predators consume prey for energy. Predators that acquire prey and prey that avoid predation both increase their chances of survival and reproduction (i.e., fitness). Routine predator-prey interactions elicit mutual adaptations that improve predator offenses, such as claws, teeth, and speed, as well as prey defenses, including crypsis, aposematism, and mimicry. Thus, predator-prey interactions resemble an evolutionary arms race.
