摘要  Received 10 May, 2017 Accepted 9 November, 2017

Abstract  Insects have developed a good adaptive mechanism in response to environmental stresses in the long-term evolution.
They have developed a helpful metabolism system to resist plant allelochemicals. Insects also harbor different kinds of
symbiotic bacteria, which provide them a competitive advantage. Here, using cotton aphid as an example, we investigated
the effects of four plant allelochemicals on the differential expression of symbiotic bacteria based on transcriptome data.
We also studied the composition of symbiotic bacteria and function on pathway level in three kinds of aphids. We found that
the bacteria have a significant role in resisting the plant allelochemicals stress and host plant selection by aphids. These
results should be useful to investigate the environmental adaption mechanism of aphids in the view of symbiotic bacteria.
These results would offer a new insight for improving strategy of aphids and developing new pest control systems.
