Description

Data of chemical compounds extracted from honey bee (Apis mellifera) brood in a varroa resistant and varroa susceptible population. Samples were taken 0, 6, 12, 18, 24, and 36 hours after brood capping by immersing pupae in pentane for 10 minutes. 6 hives from each population were used, and 3 replicates were taken per hive per time point. The FAME column was calculated by adding Methyl Palmitate, Linoloate, and Stearate together, while the FAEE columb was calculateed by adding Ethyl Palmitate, Linoloate, and Stearate together. Samples were analyzed using gas chromatography.

R version 4.4.0 and RStudio version 1.4.1.748 were used to analyze the data. All packages and their version is listed in the attached R script.

Data collection

Mode of collection: Physical measurements and tests
Description of the mode of collection:
Pupae at pre-designated times (0, 6, 12, 18, 36 hours after brood capping) were removed and submerged in n-pentane for 10 minutes to remove voltile and semi-voltile compounds from the cuticular.
These compounds were analysed using gas chromatography.
Full description of methods available in manuscript.
Time period(s) for data collection: 2021-06 – 2021-08
Data collector: Swedish University of Agricultural Sciences
Instrument: Gas Chromatography - A machine that vaporizes compounds, which flows along a long tube, with different chemicals in the compound reaching a sensor at different times. By comparing to documented times it takes a chemical to reach the sensor, chemicals can be quantified
Sample: Brood cuticular compounds
Cuticular compounds extracted from Apis mellifera pupae in n-pentane
Source of the data: Research data: Unpublished, Research data
Temporal resolution: 3 month
Spatial resolution: 750 metres
