Abstract
This study investigates the ability for the two-spotted spider mite (Tetranychus urticae) to learn and prefer or averse one host plant above the other. T. urticae is a well studied herbivorous arthropod known to be able to feed and survive on hundreds of plant species due to its genetic resistance against many toxic chemicals present in the leaves of the plants. Rose, potato and lemon are being used to test their preference, with bean as a control group. The results show a statistically significant shift in preference from potato to rose, indicating the ability to learn their preferred substrate to increase their fitness. However, there was no statistically significant result in the preference versus aversion experiment which suggests that the mites do not prefer nor averse the host plants during their choice. Furthermore, experiments based on the performance of the spider mite showed that lemon was significantly less favorable than rose, potato or bean, which all three had statistically the same positive results. Overall, this study gives an insight in the adaptive learning of the two-spotted spider mite and preference versus aversion on different host plants.
