The light intensity (mumol/m^2s) of green LED light should be found, which attracts Aphis fabae best. At each of 4 replicates 20 aphids were put in a lightproof box with only one green LED at one end. All aphids that fly to the green light are caught and counted after a period of 5h. This procedure was replicated for 9 increasing light intensities.
A data frame with 36 observations on the following 3 variables.
a numeric vector denoting the concentration levels
a numeric vector with the number of aphids remaining in the box.
a numeric vector with the number of attracted aphids
