is a predatory mite that is widely used for biological control in greenhouses. One way this predator is released is in a formulation in slow-release sachets. These sachets are prepared with the predatory mite, the factitious prey mite , and a food substrate for the latter. The objective of the present study was to study the effects of microclimatic conditions in this type of formulation on the population dynamics of mites inside the sachets and on the release of predatory mites. These experiments were conducted under laboratory conditions in two trials. The ambient relative humidity affected the water content of the food substrate of the prey mite inside the sachets, with an initial value of 21.49 ± 0.42%, which was reduced to values of 4.7 ± 0.25%, 10.87 ± 1.03% and 17.27 ± 0.82% after 21 days of trials when they were exposed to low, medium and high ambient relative humidity levels, respectively. Relative humidity significantly altered the dynamics of the populations of both species inside the sachets and the exits of the predator from the sachets to the external environment.
是一种捕食性螨类，在温室中广泛用于生物防治。释放这种捕食者的一种方式是将其制成缓释小袋制剂。这些小袋中装有捕食性螨、替代猎物螨以及后者的食物基质。本研究的目的是研究这种制剂中的微气候条件对小袋内螨类种群动态以及捕食性螨释放到外部环境的影响。这些实验在实验室条件下分两次进行。环境相对湿度影响小袋内猎物螨食物基质的含水量，初始值为21.49±0.42%，在分别暴露于低、中、高环境相对湿度水平21天后，含水量分别降至4.7±0.25%、10.87±1.03%和17.27±0.82%。相对湿度显著改变了小袋内两种螨类的种群动态以及捕食性螨从小袋释放到外部环境的情况。
