HT Cotton Not Harmful to Arthropod Insects According to Chinese StudyJune 1, 2022
The genetically modified herbicide tolerant (GMHT) cotton that was planted for 2 years in China did not exhibit any harmful effects on the arthropod community and was observed to have the same abundance and diversity of the insects as that of its near-isogenic line counterpart.
The GMHT cotton variety GGK2, known to have glyphosate tolerance, and its near-isogenic non-GMHT counterpart K312 were planted for two seasons in 2019 and 2020 in an experimental station in Anyang, Henan, China. The researchers who planted them aimed to investigate the potential impact of GMHT crops on arthropod communities.
Results showed that there were no significant differences found between GGK2 and K312 in terms of the total abundance of arthropod communities and biodiversity indexes on most sampling dates. The arthropod composition on each plot was also similar. Lastly, it was noted that there was high similarity between the arthropod communities found on both plots.
The results of the study contribute to the pool of knowledge on the potential ecological and environmental risks of GMHT crops that have attracted extensive attention and controversy.
Further reading on the study can be found in the Journal of Cotton Research.
