    Abstract
    Oestrid flies (Diptera: Oestridae) do not feed during the adult stage as they acquire all necessary nutrients during the parasitic larval stage. The adult mouthparts and digestive tract are therefore frequently vestigial; however, morphological data on the alimentary canal in adult oestrid flies are scarce and a proper visualization of this organ system within the adult body is lacking. The present work visualizes the morphology of the alimentary canal in adults of two oestrid species, Oestrus ovis L. and Hypoderma lineatum (de Villiers), with the use of non‐invasive micro‐computed tomography (micro‐CT) and compares it with the highly developed alimentary canal of the blow fly Calliphora vicina Robineau‐Desvoidy (Diptera: Calliphoridae). Both O. ovis and H. lineatum adults showed significant reductions of the cardia and the diameter of the digestive tract, an absence of the helicoidal portion of the midgut typical of other cyclorrhaphous flies, and a lack of crop and salivary glands. Given the current interest in the alimentary canal in adult dipterans in biomedical and developmental biology studies, further understanding of the morphology and development of this organ system in adult oestrids may provide valuable new insights in several areas of research.

    The export button (to the right?) will allow you to export the search results of the entered query to a CSV file. To export the items, click the "Export" button.

    There are two options to select the items you want to export to a CSV. Either you export all results from a search query, or you select a subset of items from the search results.

    To select a subset of the search results, click "Selective Export" in the Export menu.

    After making a selection, click the 'CSV' button. The amount of items that will be exported is indicated in the bubble next to 'CSV'.

    The amount of items you can export is limited, but authenticating will increase this limit.
