概括

亚致命的甲暴露显著增加了东方果 (Bactrocera dorsalis) 的卵子产量和后代的活力,同时略有减少了成年人的寿命. 这表明一种涉及幼儿激素和ecdysone的荷尔蒙机制.

科学领域:

农业昆虫学
昆虫生理学
害虫管理

背景情况:

杀虫剂的低度对有益的昆虫和害虫构成风险.
东方果 (Bactrocera dorsalis) 是一个重要的农业害虫.
胺是一种常用的杀虫剂,用于对抗B. dorsalis.

研究的目的:

对B.dorsalis进行研究.
阐明胺对背脊虫繁殖和寿命的影响背后的生理机制.

主要方法:

对B.dorsalis暴露于亚致命的硫度 (LC10和LC30).
测量生育能力,卵子产量和寿命.
对维特洛根因 (Vg),维特洛根因受体 (VgR),青春激素 (JH) 和埃克迪松水平的分析.

主要成果:

显著增加了B. dorsalis的生育能力和后代的卵子产量.
显著减少女性和男性的寿命.
增加Vg和VgR的表达和Vg,VgR,JH和ecdysone的水平.

结论:

甲可能通过增加JH和ecdysone水平来增强B. dorsalis的生育能力.
这项研究提供了关于甲的生殖刺激机制的新见解.

Trophic Efficiency

Trophic Efficiency

Trophic level transfer efficiency (TLTE) is a measure of the total energy transfer from one trophic level to the next. Due to extensive energy loss as metabolic heat, an average of only 10% of the original energy obtained is passed on to the next level. This pattern of energy loss severely limits the possible number of trophic levels in a food chain.
