A long post-reproductive period in females under optimal conditions is common among phytoseiid mites which are specialized predators of Tetranychus-species. The resulting long life span provides the possibility to postpone or delay egg production during periods of prey scarcity, theoretically in both virgin and fertilized females. The latter are better as colonists. These specialized predators are also the most prolific phytoseiids. The unusual combination of large reproductive capacity and long life might be explained as an adaptation to widely fluctuating prey densities.
在最佳条件下，雌性植绥螨具有较长的繁殖后期，这在专门捕食叶螨科物种的植绥螨中很常见。由此产生的长寿命使得在猎物稀缺时期推迟或延缓产卵成为可能，理论上无论是未受精的雌性还是已受精的雌性都可以。后者作为殖民者更具优势。这些专门的捕食者也是繁殖力最强的植绥螨。巨大的繁殖能力和长寿命这种不寻常的组合可能被解释为对猎物密度广泛波动的一种适应。
