University of Agricultural Sciences, Bangalore, in association with Cornell University, New York, UAS, and AVRDC-The World Vegetable Center, Tainan, Taiwan, is organizing. The VII International Workshop on Management of Diamondback Moth and Other Crucifer Insect Pests at Bangalore, India. The workshop is from 23 to 27 March, 2015.
The workshop is expected to attract about 200 international experts and other crucifer insect pests covering various aspects of biology, behavior, distribution, ecology, host plant interaction, chemical ecology, and management tools
Crucifers are important vegetable and oilseed crops over the world. Asia accounts for 70 % of the world production of crucifer vegetables. India is the second largest producer of crucifer vegetables and oilseed crops like rapeseed and mustard. About 8.4 million tonnes of cabbage, 7.90 million tonnes of cauliflower and 7.20 million tonnes of rapeseed and mustard are produced in the country. Insect pests on these crops constitute a major production constraint.
A cosmopolitan pest, the diamondback moth attracts the attention of a number of workers across the world. A vast body of knowledge generated on the biology, ecology and management of diamondback moth and other crucifer pests were deliberated in the previous workshops. Recent developments will be discussed in the VII International Workshop that will be held at Bangalore, India.
Among the various pests that attack crucifers, the diamondback moth (Plutella xylostella), head caterpillar (Crocidolomia pavonana), butterfly (Pieris spp.), flea beetle (Phyllotreta spp.) and aphids (Brivicoryne brassicae, Lipaphis erysimi, Myzus persicae) and a number of other pests also cause significant yield losses in crucifers. In India, the share of the pest management is estimated to be 38 % of the cost of production.
Currently, the use of insecticides is the major approach to manage these pests in most parts of the world. The evolution of resistance in key pests like the diamondback moth has led to further intensification of pesticide use in crucifers. The increased cost of production of crucifers has often led to significant economic losses due to unstable vegetable market prices. Therefore, there is a dire need to advocate and promote the use of integrated approaches for managing these pests among the farmers. Particular emphasis on safe and judicious use of insecticides is the need of the hour. This would not only reduce the cost of production but also sustain the market life of effective and environmentally benign insecticides. Further to the use of insecticides, there is also a need for promoting the use of alternative and novel tools in the management of these pests.
The International Working Group on Diamondback Moth and Other Crucifer Insect Pests is an informal group of researchers worldwide who are actively engaged in research and development in crucifer pest management. This research group participates in an international workshop on the management of Diamondback Moth and Other Crucifer Insect Pests every 4 to six years. The first and second workshops were organized by AVRDC- The World Vegetable Center in Taiwan in 1985 and 1990. The third workshop was organized by the Malaysian Agricultural Research and Development Institute in Kuala Lumpur in 1996. The fourth workshop was organized in Australia in 2001 and the fifth workshop was organized by the Chinese Academy of Agricultural Sciences in Beijing in 2006.
