概括

温度和营养等环境压力因素影响蚊子Anopheles stephensi,影响疟疾传播. 低温 (LT) 暴露增加了蚊子的适应性和疟疾寄生虫的感染,表明更快的适应潜力.

科学领域:

环境科学环境科学
载体传播疾病的研究研究.
昆虫学昆虫学是一门学科.

背景情况:

气候变化和生态变化可以扩大蚊子的地理范围,增加媒介传播的疾病传播.
在印度次大陆,Anopheles stephensi 是一个重要的城市疟疾载体.
温度和营养的可用性是影响蚊子生命周期和疾病传播能力的关键环境因素.

研究的目的:

研究环境压力因素 (低温,高温,营养不良) 对Anopheles stephensi的跨代影响.
评估这些压力因素对蚊子生命史特征,载体能力和染色体适应性的影响.
预测Anopheles stephensi在不同压力条件下的适应潜力.

主要方法:

在八代的时间里,Anopheles stephensi被暴露在低温 (LT),高温 (HT) 和低营养 (NT) 条件下.
生命史特征 (生育能力,化能力,发育时间,寿命等) 被测量到了.
在第八代中分析了Plasmodium falciparum和染色体逆转的载体能力.
使用预测数学建模来估计适应率.

主要成果:

高温和低营养条件降低了蚊子的健康参数,而低温条件增加了它们.
在HT和NT线的蚊子发展得更快,而LT线的发展延长了.
与对照人群相比,LT,HT和NT线的感染率显著增加.
在NT系中观察到染色体逆转,而LT暴露表明了更快的适应潜力.

结论:

跨代暴露于环境压力因素显著改变了Anopheles stephensi生命周期,健康状况和载体能力.
低温压力增强了蚊子的适应能力和疟疾寄生虫感染.
结果为预测疟疾发病率和制定有针对性的干预策略提供了洞察力.

Factors Affecting Body Temperature

Factors Affecting Body Temperature

As a nurse, it is vital to understand the factors affecting body temperature to monitor variations and effectively evaluate deviations from regular.
Factors may include:

Responses to Heat and Cold Stress

Responses to Heat and Cold Stress

Every organism has an optimum temperature range within which healthy growth and physiological functioning can occur. At the ends of this range, there will be a minimum and maximum temperature that interrupt biological processes.

Background and Environment Affect Phenotype

Background and Environment Affect Phenotype

Although the genetic makeup of an organism plays a major role in determining the phenotype, there are also several environmental factors, such as temperature, oxygen availability, presence of mutagens, that can alter an organism’s phenotype.
An example of how genetic background affects phenotype can be seen in horses. The Extension gene in horses is responsible for their coat color. A wild-type gene (EE) produces black pigment in the coat, while a mutant gene (ee) produces red pigment. A...
