Mahmood, Tariq (1995) RESIDUAL PESTICIDE FOLBEX VA AND ITS METABOLIC PRODUCTS IN HONEY AND WAX OF TREATED BEE COLONIES. PhD thesis, Islamia University, Bahawalpur.
A number of mite infestation control products (formic acid, lactic acid, neuron, apistan and folbex-VA) were used over three years period (1990 1993) to control varroa and acarine infestation by means of colony treatment in autumn. Treatment was given to the hives located in the hilly area of Pakistan. Folbex-VA proved to be a much effective against varroa and acarine mite. The residual levels of each product was measured in the remaining feed, honey and was. The samples were taken from each hive in the year following treatments. Chemical analysis via Gas Chromatography and HPLC showed that bromopropylate, apistan, formic acid and neuron were present in honey and wax samples. Treatments of bee colonies, using four fumigation strips containing bromopropylate, left 0.004 mg/kg residues in the honey. Residues of the breakdown product 4,4 dibromobenzophenone were also dectected in the honey 0.003 mg/kg. The concentration of the pesticide and its breakdown products in the wax was found to be 500-1000 times higher (34-102 mg bromopropylate and 14-28 mg 4,4 dibromobenzophenone/kg). The concentration present in the residual feed was similar to the honey. Physico-chemical parameters of honey were also determined by employing modern techniques. However, these were found to be comparable to the reported ones.
