Kandungan Glukosa Nektar dan Madu Sebagai Sumber Pakan Lebah Pada Lokasi yang Berbeda

Abstract

Apis cerana is a beneficial honey bee. Purpose of study to compare volume and glucose content nectar and honey as food resources at Taman Kupu-kupu Gita Persada (TKGP) and Negara Ratu (NR). Study was conducted by signed 10 flowers four differents species that can produce nectar (Calliandra sp, Dimocarpus longan, Solanum torvum and Nicotiana tabacum). Volume of nectar measured by syringe, and glucose content by refractometer. As well as honey taken from 10 pots in each nest at two location was measured by same way. Nectar samples collected (morning, day, and afternoon) every week during five weeks. Data was analyzed using T test. Result of study show volume average of nectar produced by the flowers in TKGP higher than NR, except Solanum torvum at afternoon 0,5 times lower than NR and Nicotiana tabacum in TKGP 0,2 - 0,7 times lower than NR. Glucose content average of nectar produced by flowers in NR higher than TKGP, except Dimocarpus longan on the day 4,2 times and afternoon 1,6 times, Solanum torvum and Nicotiana tabacum on day at NR 2,3 times higher then TKGP. There is a positive correlation between average of volume and glucose content of nectar four species flowers in two locations, except Calliandra sp in NR has negative correlation. Average of honey volume at TKGP higher than NR, in contrast average of glucose content of honey at TKGP lower than NR. Key words: Content glucose, Nectar, Honey, The bee (A. cerana)
