How to Culture Predatory Mites

Culturing predatory mites can be a rewarding endeavor that assists in managing pest populations in controlled environments. I have found that creating the best environment for these beneficial mites is essential for a thriving culture. Here's what I do to breed and maintain a healthy population of predatory mites.

Choose the Right Species

Firstly, it’s vital to select a species that suits your specific pest control needs. Not all predatory mites target the same pests. I often go with Amblyseius andersoni or Amblyseius cucumeris since they are both effective in controlling spider mites and thrips. Research the predators preferred for your area and the types of pests present.

Creating an Ideal Habitat

The habitat you create for these mites is incredibly important. Here are the main steps to ensure they thrive:

Temperature and Humidity: Keep the temperature between 20 to 25 degrees Celsius and maintain a relative humidity of around 75%. Excessive dryness can be devastating.
Food Source: Although they are sometimes effective in pest control, predatory mites need a steady food source. I usually introduce a population of spider mites or a diet of pollen to keep them active and reproducing.
Containers: Use breathable containers that can hold conditions, like mesh or breathable cloth lids. This not only prevents them from escaping but also allows for some air circulation.

Breeding Process

Begin with a healthy stock of predators. Once I own a handful, I place them into the prepared environment. Every couple of weeks, I check the culture. You will see their population grow when conditions are suitable. Ensure that you replace the food source regularly to prevent starvation.

Maintaining the Culture

Regularly monitor the habitat for signs of pests. I recommend checking the moisture levels and temperature daily. Too high or too low can really slow down their breeding or even kill them off. Adjust as required to keep the conditions just right. Also, remove any waste or dead mites from the habitat to maintain a clean environment.

Time to Release

Once my predatory mites are thriving and I have more than I need, it's time to consider releasing them. However, make sure you follow proper protocols when doing so.

Culturing these predators takes time and patience, but seeing them in action is truly rewarding.
