概括

土壤中的除草剂残留物破坏了植物的交流,减少了天然的害虫控制. 虫避免在污染的土壤中种植的植物,影响有益的昆虫相互作用和可持续农业.

科学领域:

农业科学农业科学
生态生态学生态生态学
环境科学环境科学

背景情况:

植物释放草食诱导的植物挥发物 (HIPV) 来吸引自然敌人,这是间接防御和综合害虫管理 (IPM) 的关键组成部分.
草甘是一种广泛使用的除草剂,在土壤中持续存在,可能会改变植物生理学和物种间相互作用.

研究的目的:

调查土壤除草剂遗留物对麦植物表现,虫食草和HIPV排放的影响.
为了确定土壤除草剂遗产是否会影响掠食性母对虫感染的植物的吸引力.

主要方法:

麦植物生长在有或没有草甘应用史的土壤中.
评估了植物生长参数,虫感染水平,挥发性有机化合物 (VOC) 排放以及母鸟的偏好.

主要成果:

土壤除草剂遗留物减少了叶绿素活性和植物高度,但没有影响植物生物质或虫种群.
除草剂遗留改变了植物的VOC概况,特别影响了五种化合物.
母鸟对生长在除草剂污染的土壤中的植物的偏好有所减少,更喜欢生长在无除草剂土壤中的植物.

结论:

土壤除草剂遗留物可以微妙地改变HIPV排放,对植物-昆虫通信和自然害虫控制服务产生负面影响.
人为杀虫剂污染,如草甘,可以破坏关键的生态系统服务,影响有益的昆虫行为,并可能破坏可持续的害虫管理策略.

Defenses Against Pathogens and Herbivores

Defenses Against Pathogens and Herbivores

Plants present a rich source of nutrients for many organisms, making it a target for herbivores and infectious agents. Plants, though lacking a proper immune system, have developed an array of constitutive and inducible defenses to fend off these attacks.

Epiphytes, Parasites, and Carnivores

Epiphytes, Parasites, and Carnivores

Plants often form mutualistic relationships with soil-dwelling fungi or bacteria to enhance their roots’ nutrient uptake ability. Root-colonizing fungi (e.g., mycorrhizae) increase a plant’s root surface area, which promotes nutrient absorption. While root-colonizing, nitrogen-fixing bacteria (e.g., rhizobia) convert atmospheric nitrogen (N2) into ammonia (NH3), making nitrogen available to plants for various biological functions. For example, nitrogen is essential for the...

The Roles of Bacteria and Fungi in Plant Nutrition

The Roles of Bacteria and Fungi in Plant Nutrition

Plants have the impressive ability to create their own food through photosynthesis. However, plants often require assistance from organisms in the soil to acquire the nutrients they need to function correctly. Both bacteria and fungi have evolved symbiotic relationships with plants that help the species to thrive in a wide variety of environments.

Predator-Prey Interactions

Predator-Prey Interactions

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.
