effect of different levels of vitamin c on queen laying rate and body protein percentage of worker in honey bee colonies (apis mellifera l.)
نویسندگان
چکیده
role of vitamins in bee nutrition is very important especially in case of supplemental feeding with sugar and pollen substitutes. in this experiment effects of different levels of vitamin c on the rate of queen lying and workers body protein were studied. experimental colonies had the same age queens and the same population (5 frames). this study was held at april and july 2011 in three levels of vitamin c (2000, 4000 and 6000 ppm) with sugar syrup (50%) while the control group fed syrup without vitamin c for 45 days. results of statistical analysis showed that between treatments in terms of queen lying was significantly different (p

In order to evaluate eight different protein sources in honey bee nutrition, some experiments were conducted as a completely randomized designs with four replicates and three steps incubator, field and overwintering in Isfahan region. Protein sources were lentil flour, soybean flour, soybean meal, bread yeast, wheat gluten, skim milk powder, fish meal and Pollen. Results showed that the longevi...
متن کاملCytosine modifications in the honey bee (Apis mellifera) worker genome
Epigenetic changes enable genomes to respond to changes in the environment, such as altered nutrition, activity, or social setting. Epigenetic modifications, thereby, provide a source of phenotypic plasticity in many species. The honey bee (Apis mellifera) uses nutritionally sensitive epigenetic control mechanisms in the development of the royal caste (queens) and the workers. The workers are f...
