| 摘 要： | 为明确河北昌黎、广西资源两地不同葡萄品种来源霜霉菌致病力分化情况,本研究利用离体叶盘接种法测定了河北、广西主栽品种‘红宝石无核’、‘红地球’及‘巨峰’来源葡萄霜霉病菌对不同鉴别寄主的致病力,观察不同地区、不同寄主来源病菌对同一感病材料以及同一寄主来源病菌对不同感病材料的致病力大小是否存在差异。结果表明:不同地区同一寄主来源病菌及同一来源不同菌株间致病力均存在差异,说明两个地区病菌群体间和群体内各菌株间均存在分化;两地不同寄主来源病菌群体对同一感病材料的致病力及同一寄主来源病菌群体对不同感病材料的致病力均存在显著差异,且广西资源地区菌株间差异性比河北昌黎地区更明显,说明不同寄主来源的菌株存在一定程度的分化。

| Abstract: | Drosophila suzukii is becoming a world-wide serious pest. It is a highly polyphagous pest, mainly causing damages to soft fruits. The sensilla on the antennae and maxillary palpi were observed by scanning electron microscope technology. The results showed that there were three types of sensilla on flagellum of the antennae, including sensilla basiconica, sensilla coeloconica and sensilla trichodea. Only sensilla basiconica and sensilla chaetica were observed on the maxillary palpi. Sexual dimorphism in structure, distribution and numbers of the other sensilla was not observed. Large and small subtypes of sensilla basiconica were further distinguished. A number of large horizontal bar-shaped pores were distributed on the surface of large sensilla basiconica, while numerous small pores on the surface of small sensilla basiconica. Large sensilla basiconica, a unique type of sensillum not yet observed in other Drosophila species, was only distributed on the flagellum of D. suzukii. It might be evolved as a specific type of sensillum for D. suzukii to smell volatiles emitted by healthy and fresh fruits. |
