Chilo suppressalis

(Asiatic rice borer / Striped Rice Borer) is a moth of the family Crambidae. It is a widespread species, known from India, Sri Lanka, China, eastern Asia, Japan, Taiwan, Malaysia to the Pacific. It is a serious pest of rice. They are largely responsible for the great reduction in the rice growing.
Life cycle
Egg: are creamy white, flattened, oval and scale like and laid in mass and covered with buff coloured hairs.
Larva: pale yellow with dark brown head.
Pupa: White silken cocoon are found inside the stem.
Adult: Female moth: bright yellowish brown fore wings with a black spot possess a tuft of yellow hairs Male moth: Smaller with pale yellow forewings without black spot.

Host plants
Presence of brown coloured egg mass near leaf tip.2. Caterpillar bore into central shoot of paddy seedling and tiller, causes drying of the central shoot known as “dead heart”. 3.Grown up plant whole panicle becomes dried “white ear”. 4. Plants could be easily pulled by hand.
Larvae tunnel into the growing stems killing the plant or severely reducing grain production. Both the attack symptoms and the damage caused by the Chilo Suppressalis are different depending on the development stage of the rice plant. Frequently, the attacked plants are arranged in circles or little groups. This is due to the fact that usually, the larvae do not move very far from the plant.
During the earing period, the plant is attacked by larvae from 2nd and 3rd generation. The signs of the striped rice borer attack at this stage are plants with more vertical spikes than the rest due to the relatively little weight of the rice grains. This attack may also affect the cane itself because sometimes it is not solid enough to hold the plant’s weight and it lies down.
ETL for Chilo suppressalis is 6-8 No’s of moths per trap per day.
Use 8-10 No’s Pheromone Traps per acre from 15 days crop stage to control pest at early stage.
Trap canopy should be placed one feet above crop canopy to achieve optimum catch.
Recommended trap model: Phero-Sensor™- SP or Phero-Sensor™ - BP traps.
Recommended for: Paddy.
