  • Potato purple top affects yield and tubers quality by browning and the abnormal sprout associated with it. This disease is considered of phytoplasmic origin, although Koch postulates have not been properly proven. This investigation tries to determine etiology for browning and abnormal sprouting in potato; taking this into account isolations coming from 19 genotypes of field potato with four varieties were transmitted by means of graf, Sangema that had 52.63% transmission, Michoacán that had 42.1%, Norteña with 31.57% and NAU-6 that reached 65.2%.

    En los Yungas del departamento de La Paz, Bolivia se ubica la comunidad Carmen Pampa, fuente de recursos naturales y biodiversidad exquisita, íºltimamente está siendo afectada por los chaqueos y actividades agrí­colas convencionales, dado que no existen datos suficientes en la región para poder desarrollar alternativas agrí­colas sostenibles que cuiden el medio ambiente, de ahí­ que este trabajo tiene como propósito estudiar el comportamiento de la lombriz roja californiana (Eisenia spp.) y la lombriz silvestre (Lumbricus spp.) en dos sustratos a fin mejorar la calidad del vermicompost producido por estos anélidos. El trabajo se ha realizado en el módulo de Microbiologí­a Ambiental, en instalaciones de la Unidad Académica Campesina Carmen Pampa (UACCP), Campus Leahy, ubicado en Coroico Nor Yungas del Departamento de La Paz-Bolivia. Se ha estudiado su comportamiento en dos sustratos bosta bobina (estiércol) y rumia bovina (rumia) en 40 unidades experimentales de 0.2 m de anchoâ��0.25 m de largoâ��0.4 m de profundidad, cada unidad presentaba una densidad de 5, 10, 15, 20 y 25 individuos con dos repeticiones de cada una en 1 000 g de sustrato. Se determinó el níºmero de cocones, níºmero de individuos a las 8 semanas, porcentaje de degradación del sustrato. Los resultados indican que los sustratos estiércol son mejores en la dinámica poblacional de Eisenia spp., en comparación con Lumbricus spp. Posiblemente las caracterí­sticas fí­sicas y quí­micas del estiércol y la rumia influyeron en este tipo de comportamiento de Eisenia spp.

    In Yungas of department of La Paz, Bolivia is located the community Carmen Pampas, source of natural resources and exquisite biodiversity, lately is being affected by the chaqueos and conventional agricultural activities, due there is not enough data in the region to develop sustainable agricultural alternatives that take care of environment. Taking this into account this work has as purpose to study the behavior of the californian red earthworm (Eisenia spp.) and the wild earthworm (Lumbricus spp.) in two substrates with the aim to improve the quality of vermicompost produced by these annelids. The work has been carried out in the module of Environmental Microbiology, in facilities of Unidad Académica Campesina Carmen Pampa (UACCP), Campus Leahy, located in Coroico Nor Yungas of Departamento of La Paz-Bolivia. Their behavior has been studied in two substrates bovine dung (manure) and bovine rumination (rumination) in 40 experimental units of 0.2 m width*0.25 m length*0.4 m depth, each unit showed a density of 5, 10, 15, 20 and 25 individuals with two repetitions of each one in 1 000 g of substrate. The cocoons number, number of individuals at 8 weeks, and percentage of degradation of the substrate was determined. The results indicate that substrates manure is better in the population dynamics of Eisenia spp., in comparison with Lumbricus spp. Thephysical and chemical characteristics of manure and rumination possibly influenced in this type of behavior for Eisenia spp.
