“…These relatively recent studies have indicated that characters from the alimentary canal can be quite useful in shedding light on the higher classification of various families. Most of these studies have been cited by Gupta (1965) and Ekis and Gupta (1971) and need not be repeated here. However, comparative morphological studies on the internal systems of weevils have been rather sparse.…”

The alimentary canal and central nervous system are described and illustrated for 208 species of weevils (Curculionoidea, representing 140 genera and eight families, and the results are compared with the published data on related species.The phylogenetic importance of the alimentary canal and central nervous system of adult Curculionoidea is discussed. The alimentary canal and nervous system of the genera Car, Cylas, Eurhynchus, and Antliarhinus are described and the systematic position of these genera discussed. It is concluded that, on the basis of internal characters, Car, previously considered to belong to the Attelabidae, is better placed in the Apionidae; Cylas, now placed in the Brentidae, may be allied to both Brentidae and Apionidae; and both Eurhynchus and Antliarhinus are primitive apionids.

“…There have been numerous studies of the alimentary canal of wood borers, including those of Ekis and Gupta (1971), who reported the digestive systems of 44 species of Cleridae, Yin (1987), who studied the larvae of 12 species of longhorn beetle, and Roche and Wheeler (1997), who examined the morphology and ultrastructure of the peculiar alimentary canal of the turtle ant Zacryptocerus rohweri (Wheeler). Most Lepidoptera larvae feed on plant leaves or fruit; however, the larva of S. insularis are wood borers, which inevitably results in a specialized alimentary canal.…”

Streltzoviella insularis (Staudinger) is an important tree‐boring pest, that primarily damages Sophora japonica (Linnaeus) and Ginkgo biloba (Linnaeus), as well as other common species, at great economic cost to the urban landscape construction industry in China. In the present study, the alimentary canal morphology of S. insularis was observed using light microscopy, and its ultrastructure was investigated by scanning and transmission electron microscopy. The foregut of S. insularis can be divided into the pharynx, esophagus, crop, proventriculus, and cardiac valve. The well‐developed crop forms the longest section of the foregut. It is able to store large amounts of food and is lined with a monolayer of epithelial cells. Many sclerotized microspines occur on the surface of the anterior intima and there are dense spines on the posterior intima of the proventriculus. Epithelial cells of the midgut include columnar cells, goblet cells, and regenerative cells, but endocrine cells are absent. The hindgut consists of the pyloric valve, ileum, and rectum. There is no clear distinction between the ileum and colon. The intima surface of the pyloric valve carries many microspines, whereas the intestinal wall of the rectum is thin with well‐developed rectal pads. The rectal epithelial cells form a squamous monolayer. A cryptonephric excretory system is located in the hindgut. There are six spiral Malpighian tubules, in which a cellular layer on a basement membrane encloses a lumen. These results will provide the basis for further studies of the structure and function in S. insularis larvae.

“…The foregut of coleopterans, generally tubular, is composed of a narrow pharynx opening into the tubular esophagus. It is narrow anteriorly but may be distended posteriorly to form a crop and proventriculus (Ekis and Gupta, 1971;Sarwade and Bhawane, 2013;Sousa et al, 2013). In many insects, the crop acts as a storage organ (Crowson, 1981) whereas the muscular proventriculus is the site where food particles are broken or filtered to the midgut (Kissinger, 1963;Serrão, 2005Serrão, , 2007.…”

The structural morphology of mouthparts, the distribution of sensilla on the mouthparts, histology, and the morphology of the alimentary canal in adult Eusomus ovulum Germar, 1824 were examined under both light and scanning electron microscopy (SEM). The mouthparts are located at the tip of the short rostrum. The mandibles, the maxillae and the labial palpi comprise the moveable mouthparts. Also there are sensillae which act as chemoreceptors on the terminal segment of the snout. Alimentary canal of adult E. ovulum is divided into three main regions, foregut, midgut and hindgut. The first part of the gut is foregut, which is made up of a pharynx, esophagus, crop and proventriculus. The pharynx extends from the mouth, having muscle attachments radiating out from its surface and connecting with the head region. The esophagus is a narrow epithelial tube contiguous and posterior to the pharynx. The proventriculus consists of 8 sclerotized plates. The midgut, which is anteriorly bulbous with a tubular posterior half. Gastric caeca were found on the posterior region of the midgut. The midgut is surrounded by outer muscles and inner columnar epithelium. The hindgut has pylorus, ileum, colon, and rectum. There are three histological layers of the hindgut from lumen to hemocoel: intima, epithelium, muscles. The hindgut has a cryptonephridial attachment for the six Malpighian tubes anterior to the rectum. The aim of the present study is to contribute information on the morphology of mouthparts, and the morphology and histology of the alimentary tract of the insect.
