摘要： Entomopathogenic fungi are eco-friendly biological method to control various agricultural pests. However, it takes time during the practical application of Beauveria bassiana in thrip management. This study investigates the role of Megalurothrips usitatus Dorsal switch protein 1 (MuDSP1), which is an immune regulatory gene during fungus infection. MuDSP1 is highly expressed at the pupal and adult stages in M. usitatus. Following the infection with B. bassiana, the expression of MuDSP1 is upregulated, as well as Phospholipase A2, lysozyme, and apolipophorin in the immune pathway. The later three genes were repressed by the interference of MuDSP1, confirming the crucial role of MuDSP1 in the immune response. Interference of MuDSP1 has no effects on the mortality of bean flower thrips, but the combination of MuDSP1 dsRNA and B. bassiana infection significantly increases the mortality caused by B. bassiana. This could be due to the attenuated immune response induced by MuDSP1 dsRNA. In conclusion, this study reveals the significant role of MuDSP1 in immune response to fungi. Simultaneous application of MuDSP1 dsRNA and B. bassiana not only provides a new strategy for high-efficient biological management but also offers an alternative approach to sustainable agricultural pest control.
