Diagnosis of Varroa jacobsoni in field conditions


Apicoltura ( 10): 23-31
Diagnosis of Varroa jacobsoni in field conditions
The effects of various factors (the apiary, the hive and the physiological stage of the sample) on the diagnosis of Varroa jacobsoni infestations was studied. Examination of 100 honey bee colonies (Apis mellifera) in 5 apiaries, by means of a randomized block scheme, showed that samples should be taken periodically for diagnosis because many factors (climate, management and other uncontrolled conditions) make it difficult to predict infestation.
