桔褐天牛广泛分布于我国,是柑橘和花椒等多种经济林木的主要害虫之一.通过扫描电镜观察发现,桔褐天牛成虫头部附器感器包括12个类型;其中触角上分布有8种感器,即Bhm氏鬃毛,毛形感器,刺形感器1型、2型、3型和锥形感器1型、2型、3型;下颚须上和下唇须均分布有刺形感器1型和3型、栓锥形感器1型和2型,钟形感器和板形感器6种.该文运用扫描电镜观察桔褐天牛成虫头部附器的感器类型、分布与数量,以期为其分类及亲缘关系研究提供依据,也为进一步阐明其交配及定位寄主的机制奠定基础.
Orange brown beetle is widely distributed in our country and it is one of the major pests of many economic trees such as citrus and pepper.It has been found by scanning electron microscopy that there are 12 types of sensilla appendages on the head of adults There are 8 sensors, namely Bhm’s mane, hairy sensor, thorn sensor type 1, type 2, type 3 and cone sensor type 1, type 2, type 3; Lip and hair are distributed with barbed sensors type 1 and type 3, plug the cone sensor type 1 and type 2, the bell-shaped sensor and the plate-shaped sensor 6. In this paper, the use of scanning electron microscopy to observe adult head The type, distribution and quantity of the appendages of the appendages are expected to provide a basis for their classification and relatedness research, and also lay a foundation for further clarifying their mechanisms of mating and locating hosts.
