Abstract
For protection against great Asian bee-mites, the device of a fumigating strip is used. This is fully impregnated with potassium-nitrate and only partially coated with "AMITRAZ" active agent. The "AMITRAZ" free end of the strip is marked and lit prior to insertion in the hive. At most 15 mgs or respectively 20 mgs active cpd. is applied to the strip. In the latter case a coating of at least 0.1 mg C22H16N3O or respectively 2 mgs of C12H16O is applied in addn. For the estimation of the deg. of infestations a receptacle is placed at the base of the beehive. A known wt. pref. 15 mg active agent contg. fumigating strip is burnt, following a given time for action, pref 1 hr., it is possible to estimate the deg. of infestation by the number of dead mites found in the receptacle. If this number is low, pref under 15-20 further fumigation does not have to be applied. At least 15-20 mm-s of the strip are free from "AMITRAZ" at the marked end.
