Food consumption and food exchange of caged honey bees using a radioactive labelled sugar solution
Fig 2
Inner 80% intake ratios of caged honey bees from temporary, permanent, acute and chronic feeding regimes.
A. Inner 80% intake ratios (ratio of second highest quantity ingested to that of the second lowest quantity ingested) for pooled data from all replicates of temporary1 and permanent3 feeding of 14C-labelled sugar solution. B. Inner 80% intake ratios for pooled data from all replicates of acute2 and chronic4 feeding of 14C-labelled sugar solution spiked with imidacloprid. # indicates differences at p < 0.05, Mann-Whitney U-test. ° indicates outliers (values between 1.5 and 3 times the interquartile range) and * indicates far outliers (more than 3 times the interquartile range).
1 temporary: test bees initially provided with defined amount (25μL/100μL) of 14C labelled diet, followed by unlabelled diet ad libitum for maintenance
2 acute: test bees initially provided with defined amount (25μL/100μL) of 14C labelled diet containing LD50 or 1/50 LD50 imidacloprid, followed by unlabelled diet ad libitum for maintenance
3 permanent: test bees provided with 14C labelled diet ad libitum
4 chronic: test bees provided with 14C labelled diet containing LD50 or 1/50 LD50 imidacloprid ad libitum
