Abstract
This study focuses on the effects of familiarity and genetic proximity on adaptation to a new host plant in Tetranychus urticae. Different populations representing different combinations of related and familiar mature, recently mated females are produced for testing on an experimental set-up. The plants used in these experiments are beans as the known environment and maize as the new environment. It’s shown that familiarity and genetic proximity have a real influence on adaptation to a new host plant in T.urticae. However, it is not possible to quantify these influences due to the large variability in the data; it is therefore necessary to continue the study by carrying out certain modifications in order to improve the quality of the data and limit the number of significant deaths of females during the creation of the populations as well as during the experiment.
