概括
存储活的黑士兵幼虫可以在最少的损失下存储长达六天 (<15%). 最佳条件包括更高的温度 (10°C),更大的量和袋子,尽管这会增加体重减轻.
科学领域:
- 昆虫养殖
- 动物营养
- 可持续的农业
背景情况:
- 活着的黑兵幼虫 (Hermetia illucens) 改善了养殖动物的福利和健康.
- 昆虫养殖设施可能远离农场,需要存储和运输幼虫.
- 冷藏是一种潜在的方法,可以保持幼虫的活力,直到使用.
研究的目的:
- 评估存储活的黑兵幼虫在低温中的可行性.
- 评估不同的储存方法及其对幼虫生存和体重的影响.
- 为了确定存储期间延长幼虫寿命的最佳条件.
主要方法:
- 幼虫在不同的条件下存储:数量 (1或3公斤),容器类型 (桶或袋),的存在和温度 (6,8,10°C).
- 每天对幼虫的生存和体重进行监测,如果死亡率达到15%,则存储结束.
- 数据使用通用线性混合模型进行分析.
主要成果:
- 在测试条件下,黑兵幼虫可存储长达6天,死亡率低于15%.
- 存储温度显著影响寿命,10°C是存储时间最长的温度.
- 与水桶相比,大和聚烯袋增加了幼虫的寿命,而袋减少了死亡率.
结论:
- 活着的黑兵幼虫在冷藏时间短 (少于6天) 的情况下是可行的.
- 温度是最关键的因素,10°C是延长幼虫生存的最佳条件.
- 虽然使用和袋子等储存方法可以提高存活率,但它们与幼虫体重减轻的增加有关.

Background and Environment Affect Phenotype
6.7K
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...

Physical Methods for Controlling Microbial Growth: Temperature
246
Heat is a widely used method to control microbial growth by targeting and denaturing cellular proteins, thereby killing or inactivating microbes. This method's effectiveness is quantified using parameters such as the thermal death point (TDP), thermal death time (TDT), and decimal reduction time (D value). TDP represents the lowest temperature at which all microorganisms in a liquid suspension are eliminated within 10 minutes, whereas TDT is the time necessary to achieve sterilization at a...

Factors Influencing Microbial Growth: Temperature
184
Microorganisms display remarkable adaptations, enabling them to thrive in diverse ecological niches across a wide range of temperatures. Temperature profoundly influences microbial growth by affecting enzymatic activity, membrane fluidity, and other cellular processes.Each microorganism operates within a specific temperature range defined by three cardinal points: minimum, optimum, and maximum. Below the minimum temperature, membranes lose fluidity, halting transport processes. Above the...
