Ultrastructure of Digestive Canal of Aelia rostrata (Heteroptera: Pentatomidae)

Abstract

Aelia rostrata (Fabricius, 1803) (Heteroptera: Pentatomidae) has a piercing mouthpiece type that is supplied with a plant sap-absorbing nose type. Aelia rostrata mainly consumes wheat but also nourishes wild Gramineae species, making it an important pest known as the wheat stink bug. In this study, A. rostrata samples were collected in August-October 2014 from various fields of agricultural and wild plants in and around the Bala district of Ankara province. Then the structure of the insect digestive canal was investigated using a light microscope and scanning electron microscope (SEM). The results showed that the digestive canal of A. rostrata consists of three distinct regions: foregut, midgut, and hindgut. The foregut consists of the salivary glands, pharynx, esophagus, and proventriculus. The midgut has an anterior, median (canal structure of the midgut), and posterior midgut (bulb structure of the midgut). Hindgut has the ileum and rectum. There are Malpighian and gastric caeca depending on the ileum. In the foregut, salivary glands and stomach are composed of cylindrical epithelium, have cylindrical epithelium while the accessory salivary gland and the midgut canal are formed from cuboidal epithelium and also the proventriculus is made from pseudo-stratified epithelium. In the midgut, the cylindrical channel of the midgut causes the cubic epithelium, while the "bulb" causes squamous epithelium. In the hindgut, the ileum occurs as cylindrical epitheliums, and the rectum consists of cubic-cylindrical epithelium. This study will contribute greatly to the scientific world of studies on the digestive tract structure of insects.-

Aelia rostrata (Fabricius, 1803) (Heteroptera: Pentatomidae) delici emici ağız tipine sahip olduğu için bitki özsuyu ile beslenmektedir. Aelia rostrata, başta buğday olmak üzere yabani Gramineae türleriyle de beslenerek zarar yapmaktadır. Buğday pis böceği (Kımıl) olarak da bilinen zararlı önemli hale gelmiştir. Bu çalışmada, 2014 yılının Ağustos-Ekim aylarında Ankara ili, Bala ilçesi ve civarındaki çeşitli tarımsal ve yabani bitki alanlarından A. rostrata örnekleri toplanmıştır. Ardından ışık mikroskobu ve taramalı elektron mikroskobu (SEM) kullanılarak böceğin sindirim kanalının yapısı incelenmiştir. A. rostrata'nın sindirim kanalının üç farklı bölgeden oluştuğunu göstermiştir: ön bağırsak, orta bağırsak ve arka bağırsak. Ön bağırsak tükürük bezleri, yutak, yemek borusu ve ön bağırsaktan oluşmaktadır. Orta bağırsakta ön, medyan (orta bağırsağın kanal yapısı), arka orta bağırsak (orta bağırsağın ampul yapısı) bulunmaktadır. Arka bağırsak, ileum ve rektumdan oluşmak tadır. İleum'a bağlı olarak Malpighi tüpleri ve gastrik çekumlar vardır. Ön bağırsakta tükürük bezleri ve mide silindirik epitelden, yardımcı tükürük bezi ve orta bağırsak kanalı kübik epitelden, proventrikulus ise yalancı çok tabakalı epitelden meydana gelmektedir. Orta bağırsakta; orta bağırsak kanalı kübik epitelden, bulb yassı epitelden oluşmaktadır. Arka bağırsakta ileum silindirik epitelden, rektum kübik silindirik epitelden oluşmaktadır. Araştırma böceklerin sindirim kanalı yapısı ile ilgili çalışmalarda bilim dünyasına katkıda bulunacaktır.
