How do you check the quality of biological products?

The quality of biology is important for effective control of diseases and pests, or in the case of bumblebees, for effective pollination. This quality is already checked by a team of quality controllers before shipment, but you can choose to check the quality yourself on receipt of biological products. This leads to the question: "How do you check the quality of biological products?”

How do you check the quality of biological products?

To check biological quality, you can make use of quality control protocols. These protocols define the criteria to be checked and include instructions for the correct application or use. Because the quality of different species of natural enemies and bumblebees depends on other aspects, each organism has its own quality control protocol. Find out more about the different protocols here.
