Gundhi bug and Sucking bug

Nature of damage: Nymphs and adults both suck the sap from the developing grain at milky stage by which grain become chaffy, empty and some grains develop but break during milling.

Management of Rice root aphid

1. Soil incorporation with Carbofuran 3 G @ 1.6 g/m2 (l/2 kg. a.i. /ha) followed by root -zone spray with monocrotophos (0.05 % concentration) at 60 days after sowing. 2. This will also reduce other pest like stem borer, stem fly, leaf roller, WBPH and green leaf hoppers.

Rice root aphid

Nature of damage: 1. Nymphs and adults suck the sap from the tender roots. In heavy infestation seedlings' growth is stunted, become pale yellow in colour and do not flower. 2. The infestation starts in vegetative stage 25 -30 days after sowing and continues till ripening.

Rice field crab

 

Scientific name : Paratelphusa hydrodromus

Local name :

Damage of Rice field crab:

1. The seedlings are cut by crabs at ground level into small bits which are carried to the holes for feeding.

2. In older plants outer sheaths are cut open and the inner portions are consumed.

3. In an attacked field bits of leaves and stems can be seen floating in water.

4. In badly damaged fields, where from the plants have been cut by crabs, can be noticed in patches.

Control of Rice field crab:

1. Poison baits with warfarin 0.025% in puffed rice mixed with fried onions and fish can be kept @ 3 g /hole on the bund for three weeks.

2. Spraying methyl parathion 50EC @ 1lit./ha over a thin sheet of water in the field and draining three days after application gives good control.

3. Granular application of thimet 10G @ 2kg/ha in between rice field and bund is effective.

Paddy mite

Scientific name : Oligonychus oryzae

Local name :

Damage of Paddy mite:

Infested leaves become white between the veins and eventually get shredded with the veins remaining green.

Control of Paddy mite:

Foliar spray of dicofol 18EC@ 2.5lit./ha or profenophos 50EC @ 1 lit./ha or monocrotophos 36EC @ 1.3 lit./ha just after initial symptom check the damage due to mite.

Tarsonemid mite

 

Scientific name : Steneotarsonemus spinki

Local name :

Damage of Tarsonemid mite:

1. This mite is found between stem and leaf sheath in colonies.

2. It causes sterility and deterioration of rice grain quality along with pathogenic fungi.

3. It damages parenchmatous tissues of rice plant and reduce the amount of nutrients to the developing grain resulting in reduction of grain weight and size.

Control of Tarsonemid mite:

Apply monocrotophos 36EC@ 1.3 lit./ha at panicle initiation stage.

Rice mealy bug

 

Scientific name : Brevennia rehi

Local name :

Damage of Rice mealy bug:

Both nymph and adult of mealy bug suck the sap by remaining concealed within leaf sheath of the plant which causes stunted growth and yellowish curled leaves in sunken oval or round patches of a normal crop and the plants may either die or put forth distorted panicles with chaffy grains.

This type of damage is known as Soorai disease in T.N.

Control of Rice mealy bug:

Attacked plants should be removed and destroyed. Apply phosphamidon 85EC @ 0.6 lit./ha or monocrotophos 36EC @ 1.3 lit./ha.

Rice Thrips

 

Scientific name : Baliothrips biformis

Local name :

Damage of Rice thrips:

1. This is essentially a pest of nurseries causing severe damage.

2. The larvae and adults lacerate the tender leaves and suck the plant sap causing rolling and drying of the leaf tips.

3. In severe infestation, the seedlings are killed.

Control of Rice thrips:

Apply endosulfan 35EC @ 1.3 lit./ha or monocrotophos 36EC @1.3 lit./ha 15 days after transplanting when thrips population reaches 10-15 (adults+larvae) / hill.

Termite

 

Scientific name : Microtermes obesi .

Local name :

Damage of Termite: 

1. Termite feeding on the roots cause yellowing older leaves of plants, then wilting and finally collapsing of the plant.

2. Damaged plants can easily be pulled out by hand. Termite attack on the germinating seeds render to loss of plant stand and under severe infestation resowing is required.

3. At night, termites move above the ground and cut seedlings at ground level irregularly and also cover them with soil for consumption afterwards.

Control of Termite:

Seed treatment with chlorpyriphos 20EC @ 3.75lit./100 kg seed along with 10% solution of gum arabica just before sowing.

Rice case worm

 

Scientific name: Nymphula depunctalis

Local name:

Damage of Rice case worm:

1. Larvae cut off the leaf tips and prepare a cylindrical tube like case and dwell inside it and often float in water.

2. They move with their cases and feed on leaves by scraping patches of green tissues sometime leaving only the white epidermis.

Control of Rice case worm:

Endosulfan 35EC @ 1.3 lit./ha or monocrotophos 36EC @ 1.3 lit./ha is effective.
