The normal temperature of sealed brood is +34℃. Disease spores are activated if the sealed brood’s temperature goes down to +27 ℃. There can be more than four pupae for one worker bee to warm up in early summer. As a result, the brood area should not be opened until the temperature is at +17℃ in order to avoid a temperature drop in the sealed brood area and thereby inducing the chalk brood disease. | ||
