芦荟螨虫

虽然相比芦荟更有抵抗力，芦荟螨虫侵害十二卷正变得越来越频繁。螨虫在H. splendens, H. bayeri, H. picta, H. retusa, H. springbokvlakensis, 各种小型硬叶十二卷属（与鲨鱼掌属）的种类种被发现。芦荟螨虫难以被发现，而治理则更加困难。因此，非常有必要仔细检查新进植株，避免引入它们。

芦荟螨虫造成的植物组织组织异常生长可以用来鉴定它们。异常的组织通常出现在生长中心点，但也可能在其它部位出现。一旦发现，最要紧也是最重要的事情，就是把感染植株与其它隔离开来，以防止进一步传播。因为没有有效的治理手段，推荐把受侵害部位去除甚至丢弃整株植物，如果受侵害的部分不易分离。在后一种情况，可以保留一些健康的叶片用来叶片繁殖。之后，继续隔离植株数月，并且经常检查。

Comparing to Aloes, Haworthias are more resistant to Aloe mites. However, their infection to Haworthia species are becoming increasingly common. The mites have been found in H, splendens, H. bayeri, H. picta, H. retusa, H. springbokvlakensis, various Haworthiopsis (and Gasteria) species. Aloe mites are hard to detect and extremely difficult to treat. Therefore, it is important to carefully inspecting new arrivals to avoid bring them in.

Aloe mites can be identified by abnormally grown plant tissues caused by them. The abnormal tissues tend to form at growth centers, though they can form anywhere. Aloe mites can be spread through the air. Once found, the most immediate and most important thing is to quarantine the infected plant from the others to prevent further spreading.

There are no very effective ways to treat Aloe mites. It is recommended to discarding the infected plants, or at least the parts with abnormal tissues. Some healthy leaves can be preserved for leaf propagation. Rarer plants can be treated with pesticides including Abamectin, Spirotetramat, and Spiromesifen. Rotate between pesticides to slow the development of resistance.
