Some chromatographic methods (RP-HPLC) for analyses of different ionic liquids have been developed. The determination methods were suitable for the study of biodegradation of these substances.
Varroa destructor is an external parasitic mite that attacks honey bees Apis cerana and Apis mellifera. Varroa mites can be controlled through commercially available miticides, as well as non-chemical means. Our research work has been conducted on plants extracts reducing the mite population. We have obtained promising results for extracts of yew and walnut.
Attempts to obtain a micro-dispersion-based formulation insecticide were made. An aqueous micro-suspension of polystyrene had been used to trap pyrethroid lambda-cyhalothrin. A method of introducing the active substance into the polymer was developed. The biological efficiency of micro-emulsion of lambda-cyhalothrin with polystyrene was investigated.
