In recent years, the bagworm Oiketicus kirbyi (Guilding) has become a pest of increasing importance in Peruvian avocado orchards. A study conducted in six commercial orchards evaluated the ecology of, and feeding damage caused by, bagworms on avocado on the southern coast of Peru. In March 2009, the population of live individuals at different locations consisted of second to sixth larval instars. The sex-ratio in the previous generation of bagworms (the parents of larvae) was female-biased, and the mortality rate was higher for females than males. The percentage of mated females varied between 76.7 and 99.1% and declined when the proportion of males was low. The damage caused by bagworm larvae usually results from defoliation, but in the case of O. kirbyi on avocado, the presence of larvae on the fruits was associated with blemishes that limit the marketability of fruits; thus bagworms cause direct economic losses for avocado growers. Future studies are needed to assess the timing of larval emergence with a view to preventing widespread infestation by dispersing neonate bagworms. © 2010 Taylor & Francis. Source

To determine trends in the prevalence and identify the main risk factors associated with the development of pancreatic cancer. Study of trends in incidence and case-control population consisted of a total of 134 patients. Patients were grouped into: a) Cases: 67 patients diagnosed with pancreatic cancer treated at the Abdomen's Service of the Specialized Surgery Department of the Regional Institute of Neoplastic Diseases "Dr. Luis Pinillos Ganoza "- IREN North during the period 2008 to 2011; and b) Controls: 67 patients diagnosed with gallstones and / or benign biliary disease treated at Belen Hospital in Trujillo during the period 2008 to 2011. The trend curve of incidence of pancreatic cancer showed a curve almost constant throughout the quadrennium 2008 to 2011, with incidence rates of 5.38%, 5.08%, 5.5% and 5.0% respectively. The overall incidence was 5.37%. The trend function was Y = (1756) ± (0.001) (x), with an R2 = 0.318 (p = 0.436). The main risk factors associated with pancreatic cancer were age bigger and equal to 60 years (p = 0.0001), male sex (p = 0.007), diabetes mellitus (p = 0.002) and family history of malignancy (p = 0.016). The trend in incidence in pancreatic cancer was low and constant in its appearance was significantly influenced by age, gender, and presence of diabetes mellitus and family history of cancer. Source

This paper presents the development of a hexapod robotic research platform for academic use, this platform is characterized by having a virtual environment and a physical model, both for testing and validations. The development emphasizes on procedural character and it has defined stages: Mechanical Design, System Modeling, Embedded System and Control Interface. The mechanical design: preliminary model, motion simulation, physic of materials and manufacture. The system modeling: kinematics, dynamics and locomotion. The Embedded Design: process unit and servo-controller; while Control Interface implements all studies. Finally, the validated procedures demonstrate that is a versatile research platform, which allows validate techniques and studies, and also strengthens the teaching and learning process. © 2014 IEEE.

Iochroma amicorum M. Cueva, S. D. Sm. & S. Leiva (Solanaceae), a new species from cloud forests of Central Peru, is described and illustrated. Phylogenetic analyses of DNA sequence data suggest that Iochroma amicorum is closely related to I. nitidum, I. umbellatum, I. grandiflorum and I. tingoanum, which collectively form the “U” clade of Iochrominae. Certain morphological characteristics of calyx and corolla as well as the type of habitat appear to be common in species of this clade. Iochroma amicorum is easily distinguished from other members of the “U” clade by its campanulate or funnel-shaped corolla with short and slightly reflexed lobes, the presence of an expanded stapet at the point of filament insertion with short lateral extensions united to the corolla, and its globose usually white fruits with tinges of purple at the base. Distribution, phenology and are discussed together with the position of the new species in Iochrominae. Iochroma amicorum is assessed as Endangered according to IUCN criteria B1ab (i, iii). © 2015 Magnolia Press. Source

Deprea zamorae Barboza & S. Leiva (Solanaceae), a new species from southern Ecuador (Loja and Zamora-Chinchipe), is described and illustrated. It is most similar to D. cyanocarpa, but differs by the presence of minute teeth on the calyx, the ratio of the corolla tube length to the lobe length, the orientation of the fruiting pedicels, and the color and shape of the fruiting calyx. Its distribution does not overlap with that of any other Deprea species. A key for all Deprea species is provided. © 2013 Magnolia Press. Source
