Aporia crataegi (Linnaeus, 1758) (Lepidoptera: Pieridae) Emme Hortumundaki Sensilla Morfolojisi

Abstract

Lepidoptera familyalarının sistematik analizinde emme hortumu yapısı ve sensilla tipleri önemli morfolojik karakterlerdir. Zararlı bir tür olmasına rağmen Aporia crataegi (Linnaeus, 1758) (Lepidoptera: Pieridae)'nin emme hortumu yapısı ve sensilla tipleri üzerine bir çalışma bulunmamaktadır. Bu amaçla A. crataegi'nin sensilla tipleri ve hortum yapısı stereomikroskop ve taramalı elektron mikroskobu kullanılarak detaylı bir şekilde incelenmiştir. Sonuçlar, A. crataegi'nin emme hortumunun üç sensilla tipine (sensilla basiconica, sensilla trichodea ve sensilla styloconica) sahip olduğunu göstermektedir. Sensilla basiconica, sığ bir yuva ile çevrili tek bir terminal gözenek ve düz bir yüzeye sahip duyusal bir koniden oluşur. Sensilla trichodea (chaetica) kıl şeklindedir. Sensilla trichodea'nın kılları gözeneksiz ve pürüzsüzdür. Sensilla styloconicum'un kör uçlu, düz bir stilusu ve uzun bir peg kısmı vardır. Bu çalışmada A. crataegi'nin emme hortumu yapısı ve sensilla tipleri ile diğer lepidoptera türlerinin emme hortumu yapısı ve sensilla tiplerinin morfolojik benzerlikleri ve farklılıkları tartışılmıştır. Böylece, Pieridae dahil Lepidoptera'daki emme hortumu yapısı ve sensilla tiplerinin anlaşılmasına katkıda bulunulmuştur.

The Morphology of the Sensilla on the Proboscis of Aporia crataegi (Linnaeus, 1758) (Lepidoptera: Pieridae)

Abstract

Proboscis structure and sensilla types are important morphological characters for the systematic analysis of Lepidoptera families. There is no study on proboscis structure and sensilla types of Aporia crataegi (Linnaeus, 1758) (Lepidoptera: Pieridae) despite the fact that it is an important pest. For this purpose, the sensilla types and proboscis structure of A. crataegi were investigated by using stereomicroscope and scanning electron microscope in detail. The results show that the proboscis of A. crataegi has three sensillum types (sensilla basiconica, sensilla trichodea, and sensilla styloconica). Sensilla basiconica consists of a sensory cone with a single terminal pore surrounded by a shallow socket and has a flat surface. Sensilla trichodea (chaetica) is bristle-shaped. The bristles of sensilla trichodea are poreless and smooth. Sensilla styloconicum has a smooth stylus, blunt tip, and long peg. In this study, the proboscis structure and sensilla types of A. crataegi were discussed with morphological similarities and differences of the other lepidopteran species’ proboscis structure and sensilla types. Thus, they contribute to the understanding of proboscis structure and sensilla types in Lepidoptera including Pieridae.
