Royal jelly production (g per cell) was 0.25, 0.26 0.23, 0.25 and 0.21; average colony yield (g) per harvest 32.1, 33.2, 31.0, 34.6, and 25.0; and total colony production (g) 96.2, 99.6, 93.0, 103.9, and 75.0 in groups PS, PS+V-E, SS, SS+V-E, and C, respectively. Any form of supplementary feeding improved RJ production relative to controls. Total colony production and average colony yield per harvest were highest in those colonies fed SS+V-E or PS+V-E. A benefit of supplementary V-E was more apparent for sugar syrup than for pollen substitute; total colony production and average colony yield per harvest were significantly higher for SS+V-E colonies than for SS, whereas no such benefit was shown between the pollen substitute groups.eninfo:eu-repo/semantics/closedAccessvitamin Ehoney beessupplementary feedingroyal jellyqueen cellsArticle44258602-s2.0-22544463112Q1WOS:000230528600004Q3
