“…In general, the alimentary canal of H. hampei was similar to others Scolytinae beetles such as the Dendroctonus spp. (Díaz et al 2000Silva-Olivares 2003), Trypodendron lineatum, Gnathotrichus retusus and Gnathotichus Sulcatus (Schneider & Rudinsky 1969), Ips pini (Hall et al 2002) and Scolytus multistriatus (Baker & Estrin 1974). The length proportion was also similar among Scolytinae.…”

Neotropical Entomology 37(2): 143-151 (2008) Morfología General del Tracto Digestivo y Sistema Reproductivo de Hypothenemus hampei (Ferrari) (Coleoptera: Curculionidae, Scolytinae)RESUMEN -El estudio morfológico del tracto digestivo y el sistema reproductor de machos y hembras de Hypothenemus hampei Ferrari se describe a continuación. El tracto digestivo presenta un arreglo típico descrito para otros insectos. Ahora las diferencias morfológicas se encontraron en el buche del estomodeo, en donde se observaron estructuras espinosas y en el mesenteron se observo un número reducido de ciegos gástricos. Se evidenció por primera vez el comportamiento de la alimentación de las hembras de H. hampei, que requiere aparentemente de la ingesta del endosperma del café para poder producir huevos viables durante la oviposición. La presencia de burbujas de aire al interior del ventrículo anterior se cree que puede ser debido al hambre, más que a la respuesta al medio ambiente durante el vuelo como lo indicaban anteriores observaciones. El sistema reproductor de la hembra presenta dos ovarios y un arreglo estructural común a especímenes de la familia Curculionidae. El sistema reproductor masculino mostró una diferencia signifi cativa con respecto a otros miembros de la familia Curculionidae e incluso a otra especie de la tribu Scolytinae presentando un aedeagus esclerotizado compuesto de varios orifi cios en la porción terminal, por donde el esperma se expulsa durante el apareamiento. PALABRAS-CLAVE: Broca del café, morfología interna, comportamiento de alimentación, reproducciónABSTRACT -The alimentary canal and the reproductive tract of males and females of Hypothenemus hampei Ferrari are described. The alimentary canal of H. hampei showed the crop with several spinelike structures and the midgut with few gastric caeca. We evidenced for the fi rst time that adult females need to feed on coffee in order to produce viable eggs before and during oviposition period. The presence of air bubbles inside the anterior midgut may be due to starvation rather than the response of the environment during fl ying as previously reported. Two ovaries and the same structures and arrangements common to individuals of the Curculionidae beetles composed the female reproductive system. The male reproductive tract showed a signifi cant difference with respect to other Curculionidae and even other Scolytinae species as it showed a sclerotized aedeagus with several pore-like structures in the terminal portion where sperm is released during mating.

Fine structure of the alimentary canal of the larval blow fly Chrysomya megacephala (Diptera: Calliphoridae)

Morphology of the alimentary canal of the mature third instar larva of the blow fly, Chrysomya megacephala (F.), was examined using light, scanning, and transmission electron microscopy. Salivary structures consist of a single median deferent duct that bifurcates into efferent ducts connected to paired, tubular salivary glands comprised of closely packed conical-shaped epithelial cells with large nuclei. The crop occurs as a large, swollen diverticulum of the digestive tube and is lined internally with convoluted cuticle (epicuticle and endocuticle). The esophagus is a simple, straight tube internally lined with cuticle and externally encompassed by muscle fibers. The cardia is a bulb-like structure composed of anterior foregut tissue and posterior midgut tissue from which the peritrophic membrane (PM) is produced. The midgut begins within the cardia which is flanked posteriorly by four tubular gastric caeca that are lined internally with four to five layers of cuboidal epithelial cells bearing microvilli. Midgut tissue is lined with simple cuboidal epithelium whose cells are filled with numerous secretory granules and possessed long microvilli facing the lumen. A peritrophic membrane is contained within the midgut lumen. The larval hindgut consists of the pylorus, Malpighian tubules, ileum, colon, rectum, and anus, posteriorly. The pylorus is characterized by a single layer of epithelial cells encircled by a muscular layer and the presence of PM within the lumen. Malpighian tubules each diverge into two tubular structures totalling four long tubules of long chained cuboidal cells bearing microvilli internally. The wall of the ileum is comprised primarily of a monolayer of cuboidal epithelial cells with large oval nuclei and more intense muscular fibers surrounding the periphery. A cuticular layer surrounds the lumen containing the PM. This inner cuticle consists of a thin epicuticle that is electron-dense; whereas, the endocuticle is much thicker but less electron-dense. Myo-epithelial cells are dense in the anal region, where the PM persists.
