摘要： The phytophagous mite is highly polyphagous and widespread in warmer regions and greenhouses around the world, and so the focus of novel acaricides is shifting towards more effective, ecofriendly new chemical entity with unique modes of action. In this study, eighteen spirobutyrolactones derived from natural tetronic acid have been synthesized and their acaricidal activities against Tetranychus cinnabarinus were investigated by slide-dip method. The results of preliminary bioassay indicate that some of these compounds exhibited promising acaricidal activities, especially, compounds 6 and 18 show significant activities against T. cinnabarinus than the commercial spirodiclofen 1 (27.37% mortality), and which present 58.55% and 82.24% mortality at tested dose, respectively. The relationship between structure and acaricidal activity was also discussed based on the experimental data, and which indicate that the compounds (16, 17 and 18) with non-substituted phenyl ring (R-1 = H) show obviously better activities. Especially, we also can find that substituted benzoyl unit will help to increase the activity than substituted phenylacetyl group.
