註釋Within the rhizosphere, there are several interactions between organisms from different kingdoms; one of these interactions is the mycophagy by springtails (Order Collembola) to fungal plant pathogens. Combining laboratory and greenhouse experiments, we evaluated the potential of using a synergy between the mycophagous springtail, Folsomia candida, and the mycoparasitic fungi Trichoderma spp. (T. harzianum, T. viridae and T. longibrachiatum) to reduce the impact of vascular wilt caused by the fungus Fusarium oxysporum in cape gooseberry, Physalis peruviana. Laboratory experiments tested the dietary preference of F. candida by fungal biomass consumption in dual choice experiments; and also tested the antagonism between F. oxysporum and Trichoderma spp. Microcosm greenhouse experiments evaluated the effect of different combinations of organisms (F. candida - Trichoderma spp. - F. oxysporum) on the growth of Physalis peruviana. Our laboratory results showed a clear preference of F. candida to consume biomass of F. oxysporum instead of Trichoderma spp. However, the consumption of F. oxysporum was related to the age of the culture. In addition, antagonism experiments confirmed that all three species of Trichoderma reduced the growing area of F. oxysporum. Finally, our greenhouse experiments suggest that there is a possible effect on root growth promotion when the springtails (F. candida) are found alone or simultaneously with the beneficial fungi (Trichoderma spp.), but further experiments and analyzes are necessary in order to understand the interaction F. candida - Trichoderma spp. in the pathosystem (F. oxysporum - P. peruviana).
