Se incluye la descripción biológica y métodos naturales de control de plagas como: el picudo del camu - camu (Conotrachelus dubiae), piojo saltador o pega pega de hojas del camu - camu (Tuthillia cognata), barrenador de ramas (Xylosandrus compactus), chinche del fruto de camu – camu (Edessa sp) y la hormigas cortadoras (Atta sexdens) para el sacha Inchi.

El incremento de las áreas de monocultivo de camu camu está generando la proliferación de plagas yfitófagos que afectan a la producción del fruto en más de un 80%. El presente trabajo evalúa la aplicación delmanejo integrado de plagas (MIP) que consiste en el control cultural de podas, defoliación, y deshierbesmensuales, y control etológico con trampas amarillas y pegante entomológico así como de control biológicocon aplicación de extractos acuosos de la planta biocida Paullinia clavigera. Se realiza una comparaciónentre este tipo de manejo y el manejo tradicional (MT) en el control de plagas de camu camu en plantacionesrealizadas en suelos de altura. El experimento fue conducido mediante un diseño completo al azar (DCA), concuatro repeticiones y cuatro plantas por unidad experimental. Las variables evaluadas fueron: porcentaje dedaño en el fruto por Edessa sp y Conotrac...

In order to evaluate the response camu camu’s plants in plantations initial undergoing training pruning, an experiment was installed in EE - IIAP-Ucayali, under a design randomized complete block, with 3 replications, making use of 20 plants per experimental unit. The pruning treatments were performing at different heights from the base of the stem, it was considered T0 [witness without pruning], T1 [pruning to 10 cm from the base], T2 [pruning to 20 cm from the base] and T3 [pruning to 40 cm from the base] in plants of known provenance. The investigation was directed to evaluate the number of shoots, shoot growth, plant height, basal diameter, crown diameter and number of branches. After of 9 months of evaluation was found significant differences between the variables except in top diameter. In the variable Height, treatment T0 [witness without pruning] outstanding because they were n...

The jumping louse, Tuthillia cognata (Hemiptera: Psyllidae) is a pest that causes severe deformations in the leaf buds of Myrciaria dubia (camu camu) in the Peruvian Amazon, therefore, a study was carried out with the objective of determining the morphological characteristics of each stage of development, the duration and longevity of T. cognata adults in young shoots of camu camu. The research was carried out under laboratory conditions (temperature: 26,9 ± 2°C, relative humidity: 6,6 ± 5% and 12:12 h Light: Dark) in Pucallpa, Peru. Morphological characteristics of each stage of development, duration and longevity of T. cognata adults in young shoots of camu camu were determined. The duration from egg to adult was 17,8 ± 0,6 (12 to 23) days and longevity for females was 38,6 ± 1,3 (37 to 40) days and for males 35,6 ± 1,5 (34 to 38) days.

The objective was to study the compatibility and efficiency of Beauveria bassiana and Metarhizium anisopliae for the control of insect pests in cabbage and lettuce grown in an aquaponic system made up of Piaractus brachypomus tanks. Spore solutions of B. bassiana and M. anisopliae were prepared. The data submitted to a Completely Random Design, with four treatments, three repetitions and the averages compared by the 5% Tukey test showed that B. bassiana + M. anisopliae caused 73% mortality of Bemisia tabaci on the underside of the lettuce leaves, B. bassiana revealed 84% mortality for Brevicoryne brassicae L. in the bundle of cabbage leaves in 23 days. On the underside of cabbage leaves, B. bassiana + M. anisopliae, showed 79% mortality in just 6 days and M. anisopliae 88% in 23 days after application. The entomopathogenic fungi B. bassiana + M. anisopliae evaluated were effective for th...

The aim was to verify the initial development of camu camu plants with different organic substrates in conventional nursery bedding microsprinkler irrigation and shade management Chromatine® mesh with 50% red light. We used genetic material from mother plants Germplasm Bank of INIA-camu camu Iquitos, seeds were germinated in decomposed sawdust and kept for a period of 40 days after subculturing was performed with 10 cm in height in different substrates according treatments in nursery beds with dimensions of 1.20 m wide x 10 m long with a depth of 30 cm. After conducting assessments of height (cm) and basal diameter (mm) for a period of 120 days, it was found that the substrate manure has become the substrate for greater efficiency in plant development camu camu substrate followed by humus worm.

Camu-camu (Myrciaria dubia (Kunth) McVaugh) is a native fruit tree, which is in domestication process, therefore, knowledge of nutritional needs is essential to improve the fertilization efficiency throughout plant development. The aim of this research was to determine the nutrient content of camu-camu plants as a function of nitrogen fertilization via fertirrigation in the first year of cultivation. An experiment was carried out in a randomized complete block design, with 5 treatments as follows: 0; 40; 80; 120 and 160 kg.ha-1 of N, eight replicates and seven plants per experimental unit. The evaluated variables were as follows: total dry matter and nutrient contents in camu-camu leaves. The results show total dry matter of camu-camu plants, which were performed a significant quadratic behavior in response to increasing N doses. In Fact, N doses greater than 128 kg.ha-1 aroused a depres...
