Abstract
[Objectives] Phyllostachys violascens is an important bamboo species that can produce abundant edible bamboo shoots. However, some fly species parasitize bamboo shoots, leading to degraded shoot quality and yield decrease. The objectives of this study were to study the population dynamics and species diversity of flies in P. violascens stands. It can provide necessary biological knowledge for scientifically controlling these flies. Thus, this study is valuable for improving the shoot quality and output of artificially cultivated P. violascens. [Methods] The diversity of flies in P. violascens stands was investigated using yellow sticky traps. The effects of environmental factors on the Shannon-Wiener index of the fly community were analyzed using the multiple linear regression. In addition, the method of variation partitioning was employed to analyze the β diversity caused by environmental and spatial variables. [Results] Ten species of flies from 8 families were identified in P. violascens stands in the Dajingshan forest farm, among which Chyliza bambusae, Pegomyia kiangsuensis, Anthomyia illocata, Hydrotaea dentipes and Episyrphus balteata were the dominant species. The number of adult bamboos and that of young bamboo shoots within a radius of 1.5 m around yellow sticky traps had a significant influence on the species diversity of flies; diversity declined with increasing number of adult bamboos. Total variation of the species matrix can be partitioned as follows: spatial species variation not shared by the environmental variables comprised, 8.54%, non-spatial environmental variation, 28.84%, spatially structured environmental variation, 10.46%, and unexplained variation and stochastic fluctuations, 52.16%. [Conclusion] This study revealed the temporal dynamics of flies in P. violascens stands and illustrated the main factors affecting the species diversity of flies. These results have both practical and theoretical implications for increasing the production of bamboo shoots and also for the integrated management of the insect pests of bamboo.
