    Preference behavior towards mıneral elements by honeybee
    (Bursa Uludağ Üniversitesi, 2024-06-20) Marzouk, Wael Mahmoud; Ahmed, Ahmed Kamel
    The study was conducted to ‎‎investigate honeybee preferences for various micronutrients and their ‎‎concentrations. throughout the summer of 2021 at the Plant Protection Research Institute, ARC, Giza, Egypt, specifically at the apiary of the Bee Research Department. Forager bees showed strong avoidance responses only to high ‎mineral ‎concentrations (2, 1, 0.5%, and 0.25%) for sodium, potassium, ‎calcium, and ‎magnesium chloride‎. On the other hand, Foragers bees recorded a ‎high visitation number in low ‎concentrations (0.1, 0.05, 0.025 %, and 0.0125%) ‎for 4 minerals and tap water.‎ The honeybee ‎prefers dilute sodium chloride and ‎its low concentrations (0.0125%), which ‎recorded a higher visitation number ‎among all mineral concentrations under the ‎study. In contrast, the bees exhibited no discernible preferences for the ‎calcium chloride solutions with ‎a low visitation number of 0.1 and 0.05% ‎compared with tap water. The visitation numbers are ‎similar in magnesium and ‎potassium at 0.05, 0.025, and 0.0125% but higher ‎than tap water.‎ The solution was consumed at a ‎concentration of 0.0125 after 139 ‎minutes, a concentration of 0.025 after 142.5 min., and a ‎concentration of 0.05 after a time had passed 157.5 min. ‎The preference factor ‎for NaCl solution was recorded at a concentration of ‎‎(0.0125) Thus, the bees’ ‎preference for this concentration is higher than their ‎preference for tap water. ‎The lowest preference factor (0.4) was recorded with a ‎CaCl2 solution with a ‎concentration of (0.1). low consumption ‎ratios were recorded for 0.0125% ‎potassium chloride (indicating a preference ‎for the test solution), and higher ‎consumption ratios were reported for 0.1% ‎calcium chloride (indicating ‎avoidance of the test solution).‎
