Abstract
Observations on the seasonal variations in population of nymphs and adults of three species of grasshoppers viz., Sphinogonotus longipennis Saussure, Oedaleus abruptus (Thunberg) and Acrida exaltata (Walker) were carried out in the field during the different months of the year 2005-2006. During the field observations it was found that the population of hoppers and adults was abundant during the moths of April-August and September – October respectively in the Kashmir Valley. The mating was found during the months of September and October soon after mating eggs were laid, which remained under diapause during winter months, they hatched on the onset of spring season. The hoppers of Acrida exaltata appeared first after the winter months followed by Sphingonotus longipennis and Oedaleus abruptus respectively.
