摘要

In Beijing,the diamondback moth(DBM)has 6 generations that OCCUr from early May to early November. In the Yanqing district of Beijing,despite more than 14 sprays per year,the population of DBM increased and that of its natural enemies decreased yearly. The population of DBM surveyed in an inseeticide.free erucifer field showed that the first moth arrived in early May in 2006,and that the peaks aduIts(1 200 adults/day/trap)and larvae(25 larvae/plants)occurred on 10 May and 29 May,respectively.Experiments were carried out to control DBM using integrated pest management(IPM)at Yanqing in 2005.2006.3 000 sex pheromone traps were set in 2005 and 15 000 traps in 2006. The results showed that in the treatment area the highest number of DBM adults was 95 adults/day/trap on 19 May and larvae 0.3 larvae/plants on 26 May,while in the control area,peak adults(66 adults/day/trap)and larvae (11.3 larvae/plants)occu~ed on 22 May and 29 June.Sex pheromone traps and 1-2 sprays of biological insecticides Were used in the spring crucifer field at Yanqing in 2005 to control DBM. The results indicated a higher monetary value in the treatment area compared to the control area.By using sex pheromone traps,the number of insecticide sprays were decreased and eeonomic and ecological benefits were gained.
