概括

补充花粉养可以减轻昆虫杀虫剂flonicamid对掠食虫Amblydromalus limonicus的负面影响. 渐进的花粉应用改善了虫种群的增长,即使暴露于农药残留物.

科学领域:

农业昆虫学农业昆虫学
病虫害管理科学病虫害管理科学
生物控制生物控制

背景情况:

使用掠食性虫进行生物控制对于温室害虫管理至关重要.
综合虫害管理 (IPM) 常常将生物控制与降低风险的农药结合起来.
植物类虫在猎物稀缺期间需要像花粉这样的替代食物来源.

研究的目的:

评估补充花粉对暴露于弗洛尼卡米德的Amblydromalus limonicus的生存,繁殖和掠食的影响.
为了比较单次与逐渐花粉应用频率的影响.

主要方法:

掠食性虫 (Amblydromalus limonicus) 被暴露在弗洛尼卡米德杀虫剂中.
测试了两种花粉供应制度 (单次与逐步).
对虫的生存,繁殖和猎物消耗进行了监测.

主要成果:

花粉供应减少了整个猎物消费,但减轻了农药诱导的减少.
逐渐的花粉应用积极影响了暴露在flonicamid中的虫的内在种群增长率 (rm).
花粉减轻了农药对掠食性虫的负面副作用.

结论:

花粉供应在减轻农药对掠食性虫的副作用方面发挥着至关重要的作用.
战略性花粉补充可以提高IPM计划中的生物控制剂的有效性.

关键词:

这种植物叫Amblydromalus limonicus.弗洛尼卡米德 (flonicamid) 是一种数字响应的数字响应.业绩表现表现的表现表现是什么对于花粉来说,这是一个很好的选择.有副作用的副作用.

Pollination and Flower Structure

Pollination and Flower Structure

Flowers are the reproductive, seed-producing structures of angiosperms. Typically, flowers consist of sepals, petals, stamens, and carpels. Sepals and petals are the vegetative flower organs. Stamens and carpels are the reproductive organs.

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.

Frequency-dependent Selection

Frequency-dependent Selection

When the fitness of a trait is influenced by how common it is (i.e., its frequency) relative to different traits within a population, this is referred to as frequency-dependent selection. Frequency-dependent selection may occur between species or within a single species. This type of selection can either be positive—with more common phenotypes having higher fitness—or negative, with rarer phenotypes conferring increased fitness.

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.
