The Occurrence Characteristics and the Correlation Study of Aceria pallida Keifer and Bactericera gobica Loginova
Abstract:Objective:To study the occurrence and correlation of phoretic gall mite Aceria pallida Keifer and its phoretic host Bactericera gobica Loginova,and to provide a scientific basis for their prevention and control.Methods:The braches of wolfberry trees were isolated with a 60-mesh net and then released different numbers of adult psyllids,investigated the mite galls and their association with the psyllids.The field occurrence of A.pallida and B.gobica was investigated,and the control strategy of this phoretic gall mite was analyzed and discussed.Results:The number of mite galls inside the mesh net was dependent on the number of released adult psyllids.The maximum occurrence of gall mite was in May and in August,and the mite galls and psyllids showed a significant correlation in early spring and autumn.Conclusion:The phoretic mites on the psyllids are the exclusive source of mites in early spring.The management of A.pallida should pay more attention to its phoretic host B.gobica in early spring.
