樟子松梢小卷蛾产卵器、复眼和口器感受器的扫描电镜观察

为了研究樟子松梢小卷蛾Rhyacionia pinicolana (Doubleday)（鳞翅目:卷蛾科）的产卵器、复眼和口器上感受器的外部形态、类型和分布特点,从野外采集被害的樟子松侧枝,在室内培养出樟子松梢小卷蛾成虫,通过QUANTA-200型扫描电镜对其进行了观察。观察表明,在樟子松梢小卷蛾产卵器、复眼和口器上共有4种类型感受器,分别是着生于产卵器上的毛形感受器(STⅠ,STⅡ,STⅣ),着生于口器上的毛形感受器Ⅲ型(STⅢ)、栓锥形感受器(SS)和腔锥感受器(coe),着生于复眼上的锥形感受器(SBa)。樟子松梢小卷蛾上观察到的这4种类型的感受器,在形态、类型和分布上,与其他鳞翅目昆虫相同部位观察到的不尽相同。

The Sensory Receptors of the Ovipositor,Compound Eye and Mouthpart of Rhyacionia pinicolana (Doubleday): Observation with Scanning Electron Microscopy

To study the external morphology, types and distribution characteristics of ovipositor, compound eye and mouthpart of Rhyacionia pinicolana (Doubleday), the shoots of scotch pine, Pinus sylvestris var. mongolica, damaged by moths were collected from forest fields, and then the moths were raised to adults indoor, the adults were observed with scanning electron microscopy of QUANTA-200. The results showed that four sensillas were indentified in the ovipositors, compound eyes and mouthparts. The sensilla trichodea (STⅠ, STⅡ, STⅣ) were found in ovipositors. The sensilla trichodea (STⅢ), sensilla styloconica (SS) and coeloconical sensilla (coe) were found in mouthparts. The sensilla basiconca (SBa) were found in compound eyes. The 4 types of sensillas in Rhyacionia pinicolana (Doubleday) are not identical with those observed in the same parts of other lepidoptera in terms of morphology, type and distribution.
