Scientific Name: Hieroglyphus banian
Though, it is a minor pest, it occasionally assumes a serious form.
Marks of Identification:
Adults are medium sized (50 mm in length), uniformly greenish in colour with bluish hind tibia. There are three dark streaks on prothorax. Nymphs are brownish but turn greenish as they grow.
Nature of Damage: Life History: Control Measures: Chemical Control:
Both nymphs and adults feed on foliage and also on developing ears.
Eggs are laid in the soil in batches of 30 to 40, especially along the bunds or in fallow lands. They remain hibernating till the next season and hatch immediately after the first shower of rains and tiny nymphs feed initally on grasses but later on migrate to the main crop. The nymphs become full gron in 70 to 80 days, after moulting 4 to 5 times. There is only one generation in a year.
i) If the pest occurs regularly in a particular area. it is better to plough the fields to expose egg massess to predators.
ii) Scraping the bunds and destroying eggs masses.
i) As in case of jowar grasshopper.
ii) Dust Methylparathion 2% @20 kg/ha.
