Extracellular DNA, released by damaged plant cells, acts as a damage-associated molecular pattern (DAMP). We demonstrated previously that the small brown planthopper (Laodelphax striatellus, SBPH) secreted
DNase II
when feeding on artificial diets. However, the function of
DNase II
in insect feeding remained elusive. The influences of
DNase II
on SBPHs and rice plants were investigated by suppressing expression of
DNase II
or by application of heterogeneously expressed
DNase II
. We demonstrated that
DNase II
is mainly expressed in the salivary gland and is responsible for DNA-degrading activity of saliva. Knocking down the expression of
DNase II
resulted in decreased performance of SBPH reared on rice plants. The dsDNase II-treated SBPH did not influenced jasmonic acid (JA),
salicylic acid
(SA), ethylene (ET) pathways, but elicited a higher level of H

O

and callose accumulation. Application of heterogeneously expressed
DNase II
in
DNase II
-deficient saliva slightly reduced the wound-induced defence response. We propose a
DNase II
-based invading model for SBPH feeding on host plants, and provide a potential target for pest management.
