padi nymphs were maintained individually in plastic dishes containing a layer of agar solution and leaf disk of signal grass, as described above.
padi fed with signal grass is lower, the aphid's fecundity is higher when compared to lower temperatures, explaining population spikes at certain times of the year.

The 15-m-wide riparian buffer at Gallagher's Grass (GG) was planted with signal grass (Brachiaria decumbens), a low-growing perennial, which forms a dense vegetation cover.
A 50-m-wide signal grass buffer with 4 vetiver grass (Vetiveria zizanioides L.
