摘要

脂肪体是糖原、脂质和蛋白质的主要储存区。营养细胞是脂肪体的主要细胞,储存这些大分子。脂肪体由两部分组成;外围和内脏周围。外周脂肪体位于表皮下方,而内脏脂肪体位于消化道周围。这项研究于2018年至2020年间在埃格大学的埃格米克尔分析实验室和组织学实验室进行。通过组织化学和超微结构研究,在三个选择的切片中对昆虫各阶段的脂肪体含量进行了比较研究。我们鉴定了储存在滋养细胞中的大分子。清晰地观察到脂滴周围的蛋白质颗粒形式和糖原星号结构。研究发现,与所有若虫期相比,营养细胞中蛋白质的积累仍在继续,但成虫中糖原的积累显著减少。我们还发现,较大的脂滴储存在PF脂肪体内,而糖原和蛋白质在PV脂肪体内的积累要高得多。这些结果可能有助于理解昆虫体内氨基酸、氮、脂质和碳水化合物代谢以及蛋白质合成等活动的潜在机制。

Doğu hamam böceği Blatta orientalis (L., 1758) (Blattodea: Blattidae)’in trofositlerindeki makromoleküllerin histokimyasal ve ince yapı analizi
The fat body is a major storage area for glycogen, lipid and protein. The trophocyte is the main cell of fat body and stores these macromolecules. The fat body consists of two parts; peripheral and perivisceral. Peripheral fat body is located below the integument while perivisceral fat body is around the digestive tract. The study was conducted in EGEMIKAL Analysis Laboratory and Histology Laboratory of Ege University between 2018 and 2020. The fat body contents of insects at all stages were examined comparatively in three selected sections through histochemical and ultrastructural studies. We identified macromolecules stored in the trophocytes. Both the granular form of proteins and asterisk structure of glycogen localized around the lipid droplets were observed clearly. It was found that accumulation of protein continued in the trophocytes, but glycogen accumulation decreased considerably in adults compared to all nymphal stages. We also found that larger lipid droplets were stored in the PF fat body, while glycogen and protein accumulation was much higher in the PV fat body. These results may contribute to understanding of the mechanisms underlying activities such as amino acid, nitrogen, lipid and carbohydrate metabolism and protein synthesis in insects.

期刊介绍: The Turkish Journal of Entomology is a quarterly journal which has been published by Entomological Society. Turkish Journal of Entomology publishes original research articles in the fields of entomology and agricultural zoology in English. Authors whose native language is not English should have their paper edited professionally prior to submission. Before preparing the typescript for submission, examine the format of manuscripts already published in Turkish Journal of Entomology. According to TJE rules, biological observations made in one location in only one-year, short notes in which the first record of a single species in Turkey is announced, and research which is older than five years will not be accepted for publication unless it forms part of a longitudinal study.
