Abstract:: Taking Bradysia odoriphaga occurred in the leek field under different cultivation patterns as test material,using the method of system investigation,the occurrence dynamics of Bradysia odoriphaga on leek in open-field-cultivation and winter facilities of Changle county in Shandong province were studied.The results showed that in winter facilities,the development of Bradysia odoriphaga was slow,only a generation.Because the soil temperature of 5-10 cm solum was lower,only maintained at 9-14℃.Harm Bradysia odoriphaga reached peak during buckling canopy.Buckle canopy time and occurrence peak of adults and larvae were closely related.Buckle canopy time was early,larvae damage period and adults occurrence was early,otherwise,larvae and adults happened late.So the control of Bradysia odoriphaga shall adopt “treatment before and control after” strategy,that was irrigation control larvae with highly effective,low toxic pesticides and yellow trap adults in the winter shelter.Spring and autumn was Bradysia odoriphaga damage stage in open-field-cultivation,we should combine larvae control with root-irrigation and adults control with spray in spring.
