Respiration rates (oxygen uptake per individual) of the herbivorous mite Tetranychus cinnabarinus Boisd. and of the predatory mite Phytoseiulus persimilis A-H. were measured at 25°C for all life stages, including eggs, using a Cartesian Diver micro-respirometer.Metabolic rates (oxygen uptake per unit weight) ranged between 0.27 and 2.32 nl O μg live weight h in T. cinnabarinus, and between 0.99 and 3.69 nl O μg live weight h in P. persimilis. The difference in metabolic rate ranges is attributed to different modes of life. The metabolic rates of both species are higher than those of comparable mite species, which is attributed to their small size, rapid development and limited sclerotization.Respiration-body weight regression gave the single equation log R=-0.091+1.213 log W for all post-embryonic stages of T. cinnabarinus but two equations for P. persimilis of log R=0.394+1.116 log W for gravid females and log R=0.880+0.348 log W for all non-reproducing post-embryonic stages. The single respiration-body weight relationship for T. cinnabarinus reflects the continuous growth pattern of this species, and the two relationships for P. persimilis reflect the accelerated growth following fertilization. The significance of these results for invertebrate population metabolism studies is discussed.
使用笛卡尔潜水微呼吸计，在25°C下测量了植食性朱砂叶螨（Tetranychus cinnabarinus Boisd.）和捕食性智利小植绥螨（Phytoseiulus persimilis A-H.）所有生命阶段（包括卵）的呼吸速率（个体耗氧量）。朱砂叶螨的代谢率（单位体重耗氧量）在0.27至2.32 nl O μg活体重 h之间，智利小植绥螨的代谢率在0.99至3.69 nl O μg活体重 h之间。代谢率范围的差异归因于不同的生活方式。这两个物种的代谢率均高于同类螨类物种，这归因于它们体型小、发育快和几丁质化程度有限。呼吸-体重回归得出，朱砂叶螨所有胚后阶段的单一方程为log R = -0.091 + 1.213 log W，但智利小植绥螨有两个方程，妊娠雌螨的方程为log R = 0.394 + 1.116 log W，所有非繁殖胚后阶段的方程为log R = 0.880 + 0.348 log W。朱砂叶螨单一的呼吸-体重关系反映了该物种的持续生长模式，而智利小植绥螨的两个关系反映了受精后的加速生长。讨论了这些结果对无脊椎动物种群代谢研究的意义。
