Studying the Effect of Some Plant Extracts Using Hexane on Varroa Destructor and Apis Mellifera in Laboratory

Abstract

This study was conducted in the laboratories of the Technical College of Al-Mussaib, AL-Furat Al-Awsat Technical University for the period of time (1/9/2019 -1/4/2020), The experiment was in a laboratory to test the efficiency of hexane extract of garlic, thyme, and mentha, in controlling Varroa destructor on honey bees, Apis mellifera. The results showed that the thyme hexane extract had a high effect on Varroa mites that infected honey bees, where the mortality rates were (0.78, 2.67, 2.78, 3.00,and 3.33) mites / hour after (1, 24, 48, 72, and168) hour respectively. In a row with little effect on bees, It achieved the lowest mortality rate (2.44, 3.00) bees / hour after (24, 48) hours respectively . While the hexane extract of garlic showed less effect on varroa mites where it reached (0.11, 1.44, 2.00, 2.11,and 1.89) varroa / hour after (1, 24, 48, 72,and 168) hours of treatment, which was not significantly different from the hexane extract of mentha . While the effect was high on bees, reaching (4.78, 5.22) bees / hour after 48,168 hours of treatment. respectively .use (while) too much in all paper
