摘要：

为了评价新型转基因棉花在长江生态区对棉田生态环境安全性的影响, 2013-2015年作者以新型转RRM2基因棉花(Gossypium hirsutum)为材料, 以其亲本‘中棉所12’为对照, 在安徽省沿江棉区系统研究了转基因棉田昆虫群落、害虫亚群落和天敌亚群落的结构与组成、个体数量、群落特征参数及其季节性动态变化。结果表明: 转RRM2基因棉田的主要类群组成、优势类群与非转基因棉田没有差异, 但在2013年转RRM2基因棉田棉蚜个体数量显著高于非转基因棉田, 叶螨类、棉铃虫和其他鳞翅目的个体数量显著低于非转基因棉田, 在其他年份没有显著差异; 其他类群的个体数量在两类棉田间没有显著差异。在棉田害虫发生量大的年份, 转RRM2基因棉田的昆虫群落个体数量较非转基因棉田增加, 物种丰富度较非转基因棉田减少, 但差异不显著, 而两类棉田年度间均差异显著。转RRM2基因棉田昆虫群落和害虫亚群落的全生育期多样性指数、均匀度指数和优势集中性指数与非转基因棉田没有显著差异; 其天敌亚群落的三个指数在2013年与非转基因棉田差异显著, 其他年份没有显著差异; 两类棉田年度间差异均不显著。转RRM2基因棉田昆虫群落、害虫亚群落和天敌亚群落个体数量、群落特征参数的时序动态与非转基因棉田较一致, 具季节性波动; 在群落个体数量高峰期, 群落多样性指数和均匀度指数处于低谷, 而优势集中性指数则相反; 昆虫群落、害虫亚群落的季节波动明显, 天敌亚群落的季节性变化较平缓。因此, 转RRM2基因棉花对棉田昆虫群落的结构与组成、群落特征参数及其时序动态没有显著影响, 但在气候适宜年份, 转RRM2基因棉田的害虫发生量可能增大。

Abstract

We evaluated the environmental safety of the transgenic RRM2 (RNA recognition motif 2) cotton on insect communities in the Changjiang River Ecological Zone. From 2013 to 2015, we recorded and systematically monitored the structure and composition, community characteristics, diversity, abundances and seasonal changes of the insect community, pest sub-community and natural enemy sub-community in the transgenic cotton fields. We found that the composition of main functional groups in transgenic cotton fields was similar to non-transgenic cotton fields. The transgenic RRM2 cotton fields had significantly higher aphid numbers than non-transgenic cotton field in 2013. In comparison, the number of cotton spider mite, cotton bollworm and other Lepidoptera were markedly lower in transgenic RRM2 cotton field than in non-transgenic cotton field in 2013. There was no significant difference in the other two years and other functional groups. We also found that abundances of insects increased, but species richness decreased, in the transgenic RRM2 cotton fields compared to the non-transgenic cotton fields during pest outbreak years. However, there was little difference of individual numbers and species richness of insect community in transgenic RRM2 cotton fields relative to non-transgenic one, but differed significantly during three years. Indices of diversity, evenness and dominance of insect community and pest sub-community did not vary by cotton type during years, the same as that of natural enemy sub-community except for that in 2013. Although there were seasonal fluctuations in the number of individuals and community characteristics of insect community, pest sub-community and natural enemies, these temporal dynamics did not vary between the RRM2 gene cotton fields and non-transgenic cotton fields. However, during peak abundances, indices of diversity and evenness of communities were at their lowest, while the reverse was true for index of dominance. Seasonal fluctuations were obvious with the insect community and pest sub-community, but that of natural enemy community varied more moderately across seasons. Overall therefore, RRM2 transgenic cotton did not significantly differ from non-transgenic cotton fields in insect community structure and composition and temporal dynamics of community characteristics, but the occurrence of insect pests in RRM2 transgenic cotton field might increase in years with suitable climate.

Key words: insect community, biodiversity, structure and composition, transgenic RRM2 cotton
