Abstract:
In arid trans-Himalayas, a rise in pest attacks indicates changing climate conditions and many of the undeclared pests are entering into the region and earlier established pests are entering to the places where they were not observed. Onion maggot (Delia antique) is a serious pest of onion and related Allium crops in temperate region throughout the world. 50-65 percent losses were reported if crops are not protected. In cold arid region Ladakh onion maggot are found in all major onion growing areas which cause severe damage to onion crop. Survey and management was carried out in Nimoo village where the intensity of the problem of onion maggot in onion crop is very severe. Its infestation is causing 50-65 per cent loss in onion bulb yield. Location specific scientific interventions using bio-insecticides and insecticides were evaluated suiting to their own regular practices. Most of the Insecticide and bio-insecticides evaluated under in-vitro conditions were found effective against Delia antique (Onion Maggot). Survey revealed that preventive measures is the first choice of the farming community. Use of insecticides and bio-products performed significantly very effective against onion maggot. Insecticide performed better among all the treatments tested under in-vivo conditions.
