The data are issued from an empirical laboratory research on the banana weevil movements. The data set 'records.txt' contains detection records of individuals moving between 2 patches. It permits to determine the population dynamics of weevils. The data set 'alldata5.txt ' contains the individual responses to environmental conditions (sex ratio, population density) when the 'records.txt' data set is analysed for a time interval of 5 minutes. The data set 'alldata10.txt' contains the individual responses to environmental conditions (sex ratio, population density) when the 'records.txt' data set is analysed for a time interval of 10 minutes. The data set 'alldata15.txt ' contains the individual responses to environmental conditions (sex ratio, population density) when the 'records.txt' data set is analysed for a time interval of 15 minutes. The data set 'alldata20.txt ' contains the individual responses to environmental conditions (sex ratio, population density) when the 'records.txt' data set is analysed for a time interval of 20 minutes. The data set 'alldata25.txt ' contains the individual responses to environmental conditions (sex ratio, population density) when the 'records.txt' data set is analysed for a time interval of 25 minutes. The data set 'alldata30.txt ' contains the individual responses to environmental conditions (sex ratio, population density) when the 'records.txt' data set is analysed for a time interval of 30 minutes. The data set 'alldata60.txt ' contains the individual responses to environmental conditions (sex ratio, population density) when the 'records.txt' data set is analysed for a time interval of 60 minutes. The data set 'id.txt ' contains the individual characteristics (sex, identification number). The data set 'Starting_Dates.txt ' contains the experimental conditions of repetitions.
