青花菜是近年闽东南沿海地区发展迅速的一种出口蔬菜,但其病虫害发生过重,农残超标已严重制约了该地区青花菜的可持续发展,因此,建立并推广应用可持续病虫控制技术已势在必行.本研究以福建省惠安县青花菜生产田块为研究对象,在跟踪监测种植季节(9月份到翌年3月份)主要虫害发生动态并确立重点防治对象及其关键时期的基础上,研究了灯诱、性诱和高效低毒农药对其主要虫害的防治效果,从而建立起一套青花菜田间虫害的可持续控制技术.这一研究成果对闽东南沿海青花菜及类似十字花科蔬菜生产的可持续发展具有一定的指导意义.%Broccoli is one of the most important vegetables for export that have expanded rapidly in the past decades in the southeast costal region of Fujian Province. Excessive pesticide residues due to the inappropriate usage of pesticides has become a big problem for the sustainable development of broccoli in this area, and the development of sustainable pests and diseases control techniques is currently an urgent task. In this project, study on the dynamics of insect pests in the field of broccoli and its control were carried out in Huian County, which located in the middle part of southeast costal region of Fujian Province. The dynamics of pests in broccoli fields from September to March of next year was monitored, the main insect pests and the key period for their control were determined. The effect of light trap and sexual attraction as well as the effect of environment friendly pesticides on the main pests of broccoli were determined, and a sustainable control technique was consequently established. The results of this study are important for the pollution free production of broccoli as well as other brassicaceous vegetables in southeast coastal region of Fujian.
