Abstract
|
|
|
|
In order to study the insect-insect interaction of the insect community associated with Rumex obtusifolius, this experiment was designed in such a way that the feeding of one insect could indirectly affect the subsequent insect species through the changes in host plant (plant mediatedinsect-insect interaction). Philaenus spumarius and Gastrophysa viridula were selected for the experiment. To investigate the effect of P. spumarius feeding on the ecology of G. viridula, first, statistical analyses were carried out. As results, no significant difference between Control and Experimental was found in the development patterns (Repeated Measures ANOVA, F=0.744, p=0.667) and survivorships (F=0.373, p=0.990). As the results from this experiment show, there was no effect on the ecology of G. viridula due to the previous feeding by P. spumarius on R. obtusifolius leaves.
