Rice Hispa

Symptoms of damage:

1. The adult beetles feed on the epidermal tissue of the leaves and the grubs mine the leaf tissue and pupate there.

2. The beetles scrape the chlorophyll between the veins of the lamina resulting in whitish parallel streaks. Later, owing to indiscriminate feeding even on leaf veins, white blotches appear on leaves.

Brown & Green Hopper

Symptoms of damage:

1. The leafhoppers attack all the stages of the plant. Both adults and nymphs cause direct damage by sucking plant sap leading to stunted growth and reduced tillering.

2. At high population levels their feeding results in the drying of the plants and the infested paddy fields appear blighted. Infestation at

Gallmidge Fly (Sarha insects)

Symptoms of Damage:

1. The chief stage of Gall midge which causes damage is the maggot. The maggot feeds on the growing tip and suppresses the leaf primordial differentiation.

2. This in turn induces the development of radial ridges from the innermost leaf primordium followed by an elongation of the leaf sheath.
