Las plagas en el camu camu, se manifiestan en las distintas etapas productivas, no siendo excepción en vivero y en plantación inicial, conllevando en el tiempo a la baja de la productividad. El objetivo en este trabajo fue determinar la incidencia de Tuthillia cognata, en brotes foliares de plantas de camu camu de 3 años de sembradas en campo definitivo, para conocer el potencial de resistencia o susceptibilidad dentro de un ensayo genético de 43 progenies. Se evaluaron el número de brotes foliares/planta y el porcentaje de brotes foliares con daños por T. cognata. Se realizó el análisis de la varianza y pruebas estadísticas de medias de los datos (Tukey y Scott & Knott al 5% de probabilidad). Se determinaron diferencias estadísticas de la varianza entre progenies (p≤0,05) para “número de brotes foliares” y “porcentaje de brotes foliares con daños”. Evidenciánd...

El incremento de población de plagas de camu camu (Myrciaria dubia), viene afectando al 50-80 % de la fruta en plantaciones. La plaga más importante es el gorgojo del fruto (Conotrachelus dubiae), cuyo estado larval se alimenta de la semilla y origina pudrición de la pulpa. El objetivo de este estudio fue validar tecnologías para el manejo integrado del C. dubiae en plantaciones de restinga inundable. Se compararon dos tratamientos: T1=Testigo (sin MIP), 10 plantas sin ninguna practica de manejo o control. Y T2=Manejo integrado (con MIP), 10 plantas con aplicación conjunta de técnicas de control cultural, etológico y biocida. Se aplicó un diseño experimental completamente al azar, con 10 repeticiones, evaluándose el número de frutos producidos, porcentaje de frutos verdes, caídos y con daños por C. dubiae, así como el rendimiento de fruta. Se encontró ligera superioridad d...

The plagues in the camu camu, are manifested in the different productive stages, not being an exception in the nursery and in the initial plantation, leading to a decrease in productivity over time. The objective in this work was to determine the incidence of Tuthillia cognata, in foliar shoots of camu camu plants of 3 years of sowing in final field, to know the potential of resistance or susceptibility within a genetic test of 43 progenies. The number of foliar sprouts / plant and the percentage of leaf shoots with damage by T. cognata were evaluated. Variance analysis and statistical tests were performed on means of data (Tukey and Scott & Knott at 5% probability). Statistical differences in the variance between progenies (p≤0.05) were determined for "number of leaf shoots" and "percentage of leaf shoots with damage". Evidencing that the plants with the highest number of leaf bud...

The increase in the population of camu camu pests (Myrciaria dubia) has been affecting 50-80 % of the fruit in plantations. The most important pest is the fruit weevil (Conotrachelus dubiae), whose larva attacks the fruit, eating the seed and causing rotting of the pulp. The objective of this study was to validate technologies for the integrated management of C. dubiae in floodplain plantations. Two treatments were compared: T1=Control (without IPM), 10 plants without any management or control practices. And T2=Integrated management (with IPM), 10 plants with joint application of cultural, ethological and biocidal control techniques. A completely randomized experimental design was applied, with 10 repetitions, evaluating the number of fruits produced, the percentage of green fruits, fallen and damaged by C. dubiae, as well as the fruit yield. A slight superiority of the MIP treatment was...

The survival of species in a seasonally flooded forest leads to a better understanding of strategies for conservation and ecological restoration. This paper reports species tolerant to flooded areas by evaluating the survival of species planted for forest restoration. Of the seventeen species studied, five showed high potential for use in seasonally flooded forest restoration. In general, the species P. munguba, C. tapia, H. crepitans, S. reticulata and M. dubia had a survival rate higher than 50%. S. reticulata had the highest survival with 91,1% in non‑submergence conditions. However, C. tapia (65,6%) and M. dubia (52,8%) tolerated greater submergence. The survival of plants is directly related to characteristics of adaptation to periods and levels of flooding, which is also conditioned by the heterogeneous microtopography of Amazonian flooded forests.

Presentamos el caso del camu-camu (Myrciaria dubia - Myrtaceae), arbusto perenne con alto contenido de ácido ascórbico (1.5a 3% de la pulpa de! fruto). Se lograron avances en el campo tecnológico y socio-económico, en un horizonte de 50 años de trabajo en un área central de la amazonia no conectada por carretera a grandes mercados. En esta región, se está desarrollando, desde hace 35 años mejoramiento genético y agronómico del camu-camu, en interacción con el sistema tradicional agroforestal en humedales tipo varzea del pequeño productor. El objetivo es lograr mediante la incorporación del frutal, mayor resiliencia en un contexto de sostenibilidad del sistema productivo agroforestal, frente al cambio climático y la pobreza imperante. Las actividades son: colección, evaluación, selección, multiplicación y transferencia de tecnología. Se aplicaron técnicas de muestreo,...
