Impact of transgenic insect-resistant maize HGK60 with Cry1Ah gene on community components and biodiversity of arthropods in the fields

showed that there was no significant difference between transgenic insect-resistant maize and the non-GM maize. Through the observation and statistics of the influence on the biodiversity of arthropod in the field in Changchun, Yin et al. [34] found that there was no significant dif- ference between the community composition, community structure and the control maize of Bt-799, and the seasonal variation was also consistent. Guo et al. [35] used four methods of direct observation, air basin trap, ground trap and insect attractor for 2 years to obtain that the number of arthropods, diversity index, dominance concentration index in Langfang, and Fig 3.
