英文摘要:

[Objectives]  To determine differences in the composition, species richness, abundance, and diversity, of the insect communities visiting flowering Prunus persica in habitats with different degrees of disturbance in Wanbailin Ecological Garden, China. [Methods]  Species composition, richness, abundance and diversity of the insect communities visiting flowering P. persica in habitats with various degrees of disturbance in Wanbailin Ecological Garden were investigated by taking pictures of each habitat and sample tree. [Results]  A total of 126 individuals of 15 flower-visiting insect species were collected. The results show that TADM, ADM, TADH, ADH, TADW, TDH species richness were 7, 4, 7, 4, 10 and 8, respectively. The most similar habitats had a q value of 1.000 whereas the least similar habitats had a q value of 0.100. Flower-visiting insect community species richness at low altitude sites (R=10) were lower than at high altitude sites (R=12), but insect abundance at low altitude sites (P=46) was higher than at high altitude sites (P=82). [Conclusion]  There were significant differences among the flower-visiting insect communities associated with flowering P. persica at habitats with various degrees of disturbance in Wanbailin Ecological Garden. Pollinators of P. Persica were the dominant species. Large numbers of people visiting and taking photos and associated motor vehicle activity caused serious disturbance to flower-visiting insects during the P. Persica flowering and fruiting period. Better management of human and motor vehicle activity is required to improve pollination of P. Persica in the Wanbailin Ecological Garden.
