Mortality of confused flour beetles from carbon disulphide.

Description

Data from an experiment investigating the effect of gaseous carbon disulphide on the mortality of confused flour beetles (Tribolium confusum). Cloth cages of batches of approximately thirty beetles were suspended in a flask above a fixed volume of liquid carbon disulphide. The number of dead beetles after five hours of exposure was recorded.

Usage

bliss

Format

A data frame with 16 observations and three variables:

concentration:

concentration of gaseous carbon disulphide (mg/l)

dead:

number of dead beetles after five hours of exposure

exposed:

number of beetles exposed

Note

These data are frequently featured in textbooks and R packages, but usually the two replicates for each concentration are aggregated. The data as shown here were featured in Bliss (1935) but are originally from Strand (1930).
