- Abstract
This project aims to study the effects of five transgenic Gbve1 cotton lines on the distribution of biological community and environment safety in cotton fields by using a parent cotton line as control.ã€Method】 The cotton 3 leaf stage was taken as the starting date, all the organs of the whole cotton were observed by random survey method, and the species and numbers of all arthropods on cotton were recorded.ã€Result】 The results showed that the relative abundance of the main pests in the cotton field was not significantly different except for significant differences between transgenic cotton fields and control fields about Carmine spider mite, whitefly, leafhopper (P> 0.05), and overall, there was no significant difference between the sucking pest and the chewing pest in different cotton fields (P> 0.05); There was no significant difference in the parameters of species (H', J, C) between transgenic cotton fields and the control cotton fields (P> 0.05), and the similarity of arthropod community was higher between transgenic cotton and control cotton (0.681,4-0.820,9);ã€Conclusion】 Based on the dynamic analysis of the main insect community in different cotton fields, it has been found that the trend of insects in transgenic cotton field is basically the same as that of control cotton field, and there was no significant difference in dynamic analysis of the main insect community in different cotton fields except for individual growth period and individual insects community fluctuation dynamics of individual strains. Our results demonstrate that the transgenic cotton do not affect the structure and stability of animal community in cotton fields.
