Dorsal Abdominal Glands

The three dorsal abdominal glands in larvae of Apateticus bracteatus (Pentatomidae) secrete a mixture of compounds. Major volatile constituents of the secretion are identified, herein, as tridecane and 2-octenal. There are also trace amounts of 2-hexenal and two other unidentified compounds.Each of the glands has paired orifices that are located between tergites 3/4, 4/5, and 5/6, but only the most anterior gland is paired. In anterior glands of midinstar larvae, glandular cells associated with ducts, and interstitial glandular cells are distributed along the ventral walls of the reservoirs. In posterior glands, columnar glandular cells are located in the anterior dorsal wall of the reservoirs; secretory cells associated with ducts, and nonglandular interstitial cells are distributed throughout the ventral and posterior walls of the reservoirs. The interstitial glandular cells of the anterior gland and the columnar glandular cells of the middle and posterior glands contain cytoplasmic organelles characteristic of lipid-producing cells. In all glands the secretory cells associated with ducts secrete lipids. Evidence indicating the importance of Golgi and ER in secretion synthesis is presented. The reservoirs and ducts have a thin cuticular lining.The bearing of the results on present ideas of gland function in Heteroptera is discussed.

El estudio tuvo como objetivo comparar el efecto fotoprotector in vivo de una crema elaborada con el extracto hidroalcohólico de la macroalga parda Macrocystis pyrifera (Linnapus) Agardh frente a bloqueadores solares comerciales en la prevención de lesiones de piel. La muestra biológica fue colectada en el zócalo continental de la playa Yanyarina de San Juan de Marcona de la región Ica. El extracto hidroalcohólico (etanol-agua 1:1) se obtuvo por proceso de maceración a partir de 300 g de alga. Con el extracto se formuló y diseño el bloqueador dermocosmético empleando concentraciones 5, 10 y 15%, respectivamente, con una mezcla de alcoholes alifáticos sólidos, conformados principalmente por alcohol cetílico (C16H3O) y alcohol estearílico (C18H39O) 50/70%. Se emplearon 35 ratones albinos adultos machos de la especie Mus musculus cepa Bald C53 de peso promedio 30g. El potencial fotoprotector in vivo se evaluó a través de la aplicación tópica en la piel de los ratones, en el tercio anterior dorsal del lomo. Los animales fueron distribuidos en siete grupos de cinco. Al grupo 1 (blanco) no se le aplicó crema ni irradiación UV-B 320 ŋm; al grupo 2 (control) no se le aplicó crema y se le irradió con luz UV-B; los grupos 3 y 4 fueron tratados con bloqueadores solares comerciales y fueron irradiados con luz UV-B; a los grupos 5, 6 y 7 (intervención) se les aplicó el producto elaborado y se le irradió con luz UV-B. El efecto fotoprotector se evidenció en el análisis macroscópico y microscópico de la piel. En el análisis microscópico, el grupo 1 presento piel con estructura conservada; los grupos 2, 3 y 4 presentaron estructura alterada; mientras que el grupo 5 presentó alteración leve, el grupo 6, estructura aparentemente normal y el grupo 7 estructura normal. Se concluye que el extracto hidroalcohólico ejerce efecto fotoprotector in vivo ante la irradiación UV-B en las concentraciones trabajadas, lográndose que, a medida que se va aumentando la concentración del extracto, la estructura de la piel se ve menos alterada presentando la dermis y epidermis, la capa cornea laminar y basal aparentemente normales.

Despite its evolutionary conservation and functional importance, little is known of the signaling pathways that underlie development of the hypothalamus. Although mutations affecting Nodal and Hedgehog signaling disrupt hypothalamic development, the time and site of action and the exact roles of these pathways remain very poorly understood. Unexpectedly, we show here that cell-autonomous reception of Nodal signals is neither required for the migration of hypothalamic precursors within the neural plate, nor for further development of the anterior-dorsal hypothalamus. Nodal signaling is, however, cell-autonomously required for establishment of the posterior-ventral hypothalamus. Conversely, Hedgehog signaling antagonizes the development of posterior-ventral hypothalamus, while promoting anterior-dorsal hypothalamic fates. Besides their distinct roles in the regionalization of the diencephalon, we reveal cooperation between Nodal and Hedgehog pathways in the maintenance of the anterior-dorsal hypothalamus. Finally we show that it is the prechordal plate and not the head endoderm that provides the early signals essential for establishment of the hypothalamus.

AbstractThe nymphs I, II, III, and adult male and adult female stages of Mulcticola macrocephalus (Kellogg) (Phthiraptera, Ischnocera: Philopteridae), a monoxenous species of chewing louse infesting common nighthawk, Chordeiles minor (Forster) (Caprimulgiformes: Caprimulgidae), in North America, are described. Line drawings of whole nymphs and adults are presented, as are details of anterior dorsal head plates, metasternal plates, female subvulvar plates, and male genitalia. Ontogenetic characters exhibited during the postembryonic development of this species of chewing louse are described and discussed in relation to previous information in the literature.

Mature larva of Hydrothassa fairmairei (Brisout) is described and illustrated for the first time, based on specimens collected on Ranunculus spp. (Ranunculaceae) in Spain. A key to known larvae of genus Hydrothassa Thomson is provided. Diagnostic characters for the identification of species within this genus are number and size of abdominal dorsal tubercles, size of prothoracical setae and number of setae of anterior dorsal mesoand metathoracical tubercles. The larva of H. fairmairei is similar to that of H. marginella (Linné), but is clearly separated by the number of setae of dorsal anterior tubercle of mesoand metathorax. Notes on distribution and host plants are included.

Dario urops, new species, is described from a small stream of the Barapole tributary of Valapattanam River in southern Karna-taka and from Wayanad District, Kerala. It can be distinguished from its congeners by the presence of a conspicuous blackblotch on the caudal peduncle and a horizontal suborbital stripe, by the anterior dorsal fin lappets in males not being produced beyond fin spines, and by its vertebral count.

Abstract Urquhart, K., Pert, C. C., Kilburn, R., Fryer, R. J., and Bricknell, I. R. 2008. Prevalence, abundance, and distribution of Lepeoptheirus salmonis (Krøyer, 1837) and Caligus elongatus (Nordmann, 1832) on wild sea trout Salmo trutta L. – ICES Journal of Marine Science, 65: 171–173. Lepeophtheirus salmonis (Krøyer, 1837) and Caligus elongatus (Nordmann, 1832) were found on 100% and 90%, respectively, of 30 wild sea trout from the east coast of Scotland. Mean abundances of the same two sea lice were 7.8 and 7.7, respectively. The distribution of the two species of sea louse differed, however, with a greater proportion of L. salmonis in the posterior and anterior dorsal regions, and a greater proportion of C. elongatus in the caudal and posterior ventral regions.
