Abstract:
[Objectives]  To clarify the temporal trend in damage to different fruit crops caused by Bactrocera dorsalis (Hendel) in a plum, Prunus salicina Lindl., growing area, and thereby facilitate the development of new strategies and technology to control this pest. [Methods]  Potential host species, fruiting periods, the amount of damage to each fruit crop and the pattern of spread of B. dorsalis were investigated. The relationship between the population dynamics of this pest and meteorological factors in plum producing area of Guangxi were also analyzed using Pearson correlation and principal component analysis. [Results]  A total of 11 fruit producing species mature in different months in the plum producing area. Among the fruit producing species investigated (Eriobotrya japonica, Prunus mume, Clausena lansium, Citrus reticulate, C. reticulate, C. maxima, P. salicina and Diospyros kaki), the highest (22%) percentage of damaged fruit was recorded in P. salicina. The temporal trend of damage to different fruit crops was: Eriobotrya japonica (April) →P. salicina cv. ‘Sanyue’ and ‘Sanhua’, Prunus mume, and Clausena lansium (May to August) →Citrus reticulate cv. ‘Shatangju’ and ‘Huangdi’, C. maxima, and Diospyros kaki (September to October) →D. kaki (November). Male B. dorsalis should be trapped using sex pheromone lures between 26 April and 12 December. Two occurrence peaks of B. dorsalis adults were observed in the first half of July and the latter half of September, and occurrence was significantly correlated with air temperature. [Conclusion]  There is a clear temporal trend in the damage caused by B. dorsalis to different fruit crops and the occurrence of this pest was correlated with meteorological factors. Controlling B. dorsalis on E. japonica in April could reduce subsequent damage to P. salicina crops.
