| Abstract:
Hopper population was prevailing throughout the year in all types of orchard but it was higher in old orchard as compared to new and neglected orchard which may be due to different ecological conditions prevailing in different types of orchards. The results indicated that spraying of 0.2 per cent carbaryl in mango orchard during off-season (November 1983) does help in delaying the development of nymphal population during flowering period. This may help in avoiding the insecticidal spraying during flowering and fruit setting, and thereby protecting the pollinators in mango orchard which are active during this period. | |
