在恒温（23°C、25°C、30°C、33°C、36°C 和 39°C）下测定了 Banks 草螨 Oligonychus pratensis (Banks) 成虫前阶段的发育速率。估计了特定年龄的发育速率曲线，这些曲线表明所有阶段的速率都高度依赖于温度。这些曲线表明，最快的发育发生在 25 至 37°C 之间，预计最大发育速率在 37°C 附近。卵孵化所需的发育时间接近未成熟总发育时间的50%。通过使用专门设计的湿度室研究湿度对成年前发育的影响。室经过校准，可在 25°C、33°C、36°C 和 39°C 下提供高、中和低蒸气压差。在这些条件下，除了 39°C 的低蒸气压不足之外，湿度对发育几乎没有影响。在这种环境下，卵孵化率严重下降。这项研究表明，高温环境中的发育速度可能会导致班克斯草螨的爆发。湿度似乎并不影响发育速度，但可能是高温下卵子存活的一个重要变量。
Developmental rates of pre-adult stages of Banks grass mite, Oligonychus pratensis (Banks), were determined under constant temperatures (23, 25, 30, 33, 36, and 39°C). Age-specific developmental rate curves were estimated, and these indicated highly temperature-dependent rates for all stages. These curves showed that the fastest development occurred between 25 and 37°C, with maximum developmental rates predicted near 37°C. The developmental time required for egg hatch was nearly 50% of the total immature developmental time. The influence of humidity on pre-adult development was studied by using specially designed humidity chambers. Chambers were calibrated to deliver high, medium, and low vapor pressure deficits at 25, 33, 36, and 39°C. Under these conditions, humidity had little effect on development, except at 39°C, low vapor pressure deficit. In this environment, egg hatch was severely reduced. This study suggests that developmental rates in high-temperature environments may contribute to Banks grass mite outbreaks. Humidity did not seem to influence the developmental rate, but may be an important variable in egg survival at high temperatures.
