The result of the complementation test using one of those five lines (line name, “1A5”) was compared to those of the near isogenic line carrying BPH26 (line name, “BPH26-NIL”) and vector control (line name, “Vector”; Fig. 2). The BPH survival was significantly decreased on the transgenic “1A5” in comparison with that on the “Vector” control, and was equivalent to that on the “BPH26-NIL” (chi-square test28; Fig. 2a). Similarly, the amount of honeydew excreted on “1A5” and “BPH26-NIL” was smaller than that on “Vector” control (Fig. 2b).
