机械（振动）、热（不利温度）、光（光照）和饥饿等胁迫因素均抑制赤拟谷盗幼虫的生长。在T. p.采用高效液相色谱-电化学检测器（ECD）测定了板栗中的黄酮类化合物。酪氨酸的浓度最高，其次是OA、色氨酸和3，4-二羟基扁桃酸。OA的量远高于酪胺（OA在生物合成途径中的前体）和Synetamine（N-甲基OA）的量。与OA相比，DA、5-HT、E、NE及其有关物质的含量极低。昆虫强调振动在1，10，100，或1000 Hz，光学下24小时的光（15 W，50 Hz）的光周期，热通过改变孵化温度从初始值30 ° C，或饥饿，这导致生物胺，包括OA的水平的急剧变化。
Such stress factors as mechanical (vibration), thermal (unfavorable temperature), optical (light), and starvation reduced the larval growth of the red flour beetle (Tribolium castaneum Herbst). Various biogenic amines, including octopamine (OA), dopamine (DA), serotonin (5-HT), epinephrine (E), norepinephrine (NE), their precursors, and metabolites, in whole-body T. castaneum were measured by high-performance liquid chromatography coupled with electrochemical detection (ECD). Tyrosine occurred in the highest concentration, followed by OA, tryptophan, and 3,4-dihydroxymandelic acid. The amount of OA was much higher than that of tyramine (a precursor of OA in the biosynthetic pathway) and of synephrine (N-methyl OA). DA, 5-HT, E, NE, and their related substances occurred in extremely low quantities compared with OA. Insects were stressed by vibrating at 1, 10, 100, or 1000 Hz, optically under a 24-h light (15 W, 50 Hz) photoperiod, thermally by changing the incubation temperature from an initial value of 30-degrees-C, or by starvation, which resulted in dramatic changes of levels of biogenic amines, including OA.
