实蝇类昆虫利用视觉和嗅觉定位寄主的分子基础及应用

Molecular basis and application of host location by vision and olfaction in tephritid fruit flies

在昆虫与植物协同进化过程中,昆虫成功定位寄主植物决定其食性及生态位。实蝇类昆虫是世界范围内分布的重要果蔬害虫,在定位寄主植物过程中,实蝇视觉和嗅觉发挥重要作用,利用寄主颜色和气味模拟的诱捕装置能够有效诱杀实蝇,但诱杀效果参差不齐。因此,本文对实蝇类昆虫视觉、嗅觉定位寄主植物的行为和相关分子基础进行了阐述,介绍了有关的应用成果,并对未来的方向进行了展望,以期为建立实蝇类害虫可持续的绿色防控技术奠定基础。

During the process of coevolution between insects and plants,insects successfully localize host plants to determine their feeding habits and niche.Nevertheless,the molecular mechanism of host localizing of insects remains largely unknown.The true fruit flies(Diptera:Tephritidae)are important pests infesting fruits and vegetables all over the world.Research shows that vision and olfaction of tephritid fruit flies play critical roles in host location.Currently,the trapping device which simulates color and odor can trap and kill the tephritid fly effectively,but the effect of trapping and killing is uneven.This paper reviews the progress of the host location behavior through vision and olfaction by fruit flies as well as related molecular basis,and the application effects.Finally,the future perspective is discussed in order to pave the way for developing eco-friendly control measures against fruit fly pests.
