概括

研究人员成功地建立了人类跳的实验室殖民地, 这一突破使得对跳生物学和疾病传播的研究成为可能.

科学领域:

昆虫学
媒介性疾病研究

背景情况:

对于生物研究,生物测试和病原体传播评估来说,实验室殖民跳至关重要.
建立昆虫殖民地需要为后代收集和维护野生捕获的标本.

研究的目的:

描述收集,运输和维护成年和未成熟的Pulex irritans (人类跳) 的方法
报告首次在昆虫环境中成功生产下一代可行的Pulex irritans.

主要方法:

成年跳是通过人类着陆捕获的;未成熟的阶段是使用Berlese-Tullgren方法获得的.
使用人工食装置食血液,对人类或绵羊血液的成年生存率进行评估.

主要成果:

超过200个F0成年跳存活下来,产生蛋6周 (雄性:寿命6天,雌性:寿命10天).
在8周内产生大约900个子,F1代的出现率为80%.
在F1成年人中观察到高死亡率 (平均寿命为7天);人类血液中保持了跳.

结论:

这项研究为实验室研究Pulex irritans及其在疾病传播中的作用奠定了基础.
在实验室养3周内获得了大量的F1种群,这有助于对该物种进行实验研究.

The Colonization of Land

The Colonization of Land

Changes in the environment of the early Earth drove the evolution of organisms. As prokaryotic organisms in the oceans began to photosynthesize, they produced oxygen. Eventually, oxygen saturated the oceans and entered the air, resulting in an increase in atmospheric oxygen concentration, known as the oxygen revolution approximately 2.3 billion years ago. Therefore, organisms that could use oxygen for cellular respiration had an advantage. More than 1.5 years ago, eukaryotic cells and...
