Impact of genetic selection in insect populations using different selection designs, a simulation study
Insects are highly nutritious and rich in proteins and could help fulfil the worldwide increasing demand for proteins. Selection can provide lasting genetic improvements. Therefore, the aim of this study was to investigate the effect of genetic parameters in four different selection designs using a simulation study. Simulated were a mixed, half sib and full sib selection design and a combination of phenotypic selection and/or breeding values as selection method. The results show that in ten generations an improvement in body mass and development time is possible in all four selection designs and only minor differences between these designs were observed. Using estimated genetic parameters from literature, an improvement of 146-150% in biomass yield per year was observed. Thus, selection can provide lasting genetic improvements in insect populations, however inbreeding should be monitored and estimation of genetic parameters is necessary to prevent unfavourable correlated responses.
