Desert locusts are characterized by a highly sensitive and effective RNA interference (RNAi) response. Moreover, delivery of dsRNA into the open body cavity will elicit potent silencing effects throughout the body. On the other hand, many other insect species, such as Bombyx mori and Drosophila melanogaster, lack the ability to efficiently spread the RNAi-signal. In this study, we demonstrated that, in the serum of the desert locust, lipophorins adhere to dsRNA-fragments. Lipophorins can be subdivided into high density and low density lipophorins (HDLp and LDLp), according to their buoyant density, and we showed that both types of lipophorins can interact with dsRNA fragments. Furthermore, in the presence of (gram-positive) bacteria or fungi, LDLp induce the formation of pathogen aggregates, while no clear aggregation effects were detected in the presence of HDLp.
