One pheromone lure of Scirpophaga incertulas

Identification-

The fully grown larva is pale yellow in color with an orange-yellow head. It passes winter in rice stubbles and the destruction of rice stubbles also thus helps in reducing the incidence of this pest.

The moth has yellowish forewings with a single dark spot in the center of each wing.

The moth measures 1.3 cm long and 3.2 across with stretched wings.

Female moth has yellowish forewings with a single dark spot at their center while the male has numerous small brown spots.

Life Cycle-

A fully grown larva is formed in about 20- 40 days depending upon the climatic conditions.

A developed larva measures about 20 mm in length and is white or yellowish-white in color.

Larva makes an exit hole and pupates within the larval tunnel, usually at the base of the plant. Generally, two or three generations of this pest are completed during a single crop.

Winter and heavy rains are inimical to this pest. Stem borer completes its life cycle in 40-45 days. 

Nature of Damage-

Only larva causes damage to the crop. After hatching, the larva bores in to stem and damages it.

Damage during the vegetative stage results in the drying of the central shoot, a damage symptom called a dead heart.

Damage after flowering results in white empty straight panicles called white ears. As dead hearts and white ears harbor larvae, their collection and disposal help in reducing the incidence of this pest.

Target Plants-

Rice

Funnel Trap-

Pheromones are sex attractants. The adult female insect which is ready for mating emits species-specific chemical odor to attract males.

These specific chemicals called Pheromones are synthesized and used for insect pest management in crops. The Funnel Trap consists of a funnel section and a polythene bag.

A central pheromone dispenser holder is located on top of the funnel under an umbrella-type cover.

The traps are used in combination with pheromone dispensers. Funnel traps are useful tools for monitoring moths. They give information on the population density of the pest and help the grower determine the optimal control strategy.

These traps are designed for multi-season use and are resistant to severe weather conditions. They are very easy to assemble and clean.
