EVALUATION OF SOME CHEMICAL MATERIALS FOR CONTROLLING OF VARROA MITE, Varroa jacobsoni Oud. ON HONEYBEE
Plant Protection Research Institute, Sakha Agricultural Research Center
Abstract
The present investigation was achieved at the apiary of Sakha Agricultural Research Station, Kafr El-Sheikh Governorate during 2008 season to evaluate the efficiency of five materials, i.e., formic acid 60%, salcelate methyl 60%, Bayvarol strips, malathion powder 1% and Apitol for controlling varroa mite. All tested materials reduce mite population. Malathion powder 1% and formic acid 60% were the most effective material on varroa mite (93.75 & 89.57% reduction) on each of workers and drones after the fourth week of treatment during the first period from 1/2/2008 to 28/2/2008, respectively. Also, during the second period from 1/9/2008 until 28/9/2008, malathion powder 1% gave the highest reduction (93.15 & 94.00%) of varroa mite on each of workers and drones after the fourth week of treatment, respectively. On the other hand, the remaining materials, i.e., formic acid 60%, Apitol (2 gm), salcelate methyl 60% (2 cm3/colony) and Bayvarol strips gave a high reduction (88.19, 86.67, 84.08 & 82.0%) of varroa mite on workers after the four weeks of application during the first period, respectively. Also, during the second period formic acid 60%, salcelate methyl 60% (2 cm3/colony, Apitol (2 gm) and Bayvarol strips exhibited a high reduction (88.13, 88.11, 84.21 & 82.86%) of varroa mite on workers after the fourth week of application, respectively. At the same trend, formic acid 60%, salcelate methyl 60% (2 cm3/colony), Apitol (2 gm) and Bayvarol strips gave a high reduction (91.67, 91.11, 86.67 & 84.11%) of varroa mite on drones after four weeks of treatment during the second period, respectively. It could be concluded that bee keepers can use formic acid 60%, and salcelate methyl 60% (2 cm3/colony) safety during the above two tested periods for controlling varroa mite.
