Walker, striped rice stem borer
Chilo supressalis
Walker, from Pyralidae family and pink rice stem borer
Sesamea inferens
Walker Noctuidae, Host plants other than rice: no monophagus. Damage: Symptoms of damage to the vegetative stage causing sundep, the
end of the dry dead leaves and easily removed because the leaves have bitten by larvae present in the rod. In the stadia generative cause outs, namely cut stem stalk panicles in rice
panicle larvae that become empty. All of dried panicles are white grayish and remain standing. Infected panicles easily removed as part of the bang had been severed Suharto,

2.3.6. White Back Plant Hopper
Sogatella furcifera
- Jorv Homoptera: Delphacidae
Host plants other than rice: Corn and grass. Damage: high population generally found in early planting and direct damage to crops caused by sucking plant fluids. As a result, the plant
becomes yellowish orange and followed by symptoms such as burning Suharto, 2007.
