“…Thus, in our study case, the organic crop protection strategies used in apple orchard in Southeast France were highly diverse. This was not the case in the study of Puech et al (2014) focusing on annual crops in Brittany. One explanation could be the difference in pesticide pressure between the two case studies.…”

“…While positive links between organic agriculture and biodiversity, including natural enemy abundance, have often been reported (Bengtsson et al 2005;Hole et al 2005;Garratt et al 2011;Winqvist et al 2011), very little is known about the effects of variability in crop protection strategies within organic production systems, although this variability can be high (Letourneau and Bothwell 2008;Penvern et al 2010;Puech et al 2014). This may result in differential impacts on pest numbers and biological conservation and thus opens the way for the development of more ecological and sustainable protection strategies in organic farming.…”

Organic farming is mainly viewed as a homogeneous production system. Organic farming is also commonly thought to favor natural enemies of pests for crop protection. However, organic farming involves very different management practices and, in turn, various protection strategies. There is little knowledge on the influence of protection strategies on natural enemies in organic agriculture. Here, we analyzed crop protection strategies of 24 organic apple farmers in Southeast France. We also analyzed natural enemy communities in 12 apple orchards. We measured the impact of strategies on natural enemies using the International Organization for Biological and Integrated Control (IOBC) toxicity index. We identified four protection strategies: (1) the ecologically intensive strategy which promotes natural enemies by habitat management, (2) the substitution strategy mainly based on the use of pesticides, (3) the technologically intensive strategy which uses innovative technological methods such as exclusion nets and the integrated strategy which mobilizes a wide range of different practices. The IOBC toxicity index was 78.8±23.0 for the substitution strategy, 60.75±15.0 for the integrated strategy, 37.4±11.9 for the ecological strategy, and 31.25±1.7 for the technological strategy. We also found that the four strategies have different natural enemy communities such as the higher abundance of Forficula pubescens in the ecological strategy.

“…Consequently, raw classifications based on a priori dichotomous criteria such as organic farming vs. conventional farming or dairy cattle vs. nondairy cattle are likely to misrepresent the great variety of agricultural practices (Thenail 2002, Puech et al 2013). In our research framework, we consider that investigating the link between practices and representations requires (1) conducting one-on-one sociotechnical interviews (e.g., Landais 1998) to characterize the actual practices of individual farmers, and (2) building typologies by identifying distinct land management practices a posteriori to group farmers.…”

“…Frente a esta situación es necesario proponer estudios que permitan usar la biodiversidad vegetal existente, como las plantas biocidas, combinadas con otras técnicas, para lograr un control orgánico en el manejo integrado de plagas (MIP). La agricultura orgánica favorece el control biológico de las plagas, siendo este un posible camino para reducir el uso de pesticidas en la agricultura moderna (Puech et al, 2014).…”

RESUMENEl incremento de las áreas de monocultivo de camu camu está generando la proliferación de plagas y fitófagos que afectan a la producción del fruto en más de un 80%. El presente trabajo evalúa la aplicación del manejo integrado de plagas (MIP) que consiste en el control cultural de podas, defoliación, y deshierbes mensuales, y control etológico con trampas amarillas y pegante entomológico así como de control biológico con aplicación de extractos acuosos de la planta biocida Paullinia clavigera. Se realiza una comparación entre este tipo de manejo y el manejo tradicional (MT) en el control de plagas de camu camu en plantaciones realizadas en suelos de altura. El experimento fue conducido mediante un diseño completo al azar (DCA), con cuatro repeticiones y cuatro plantas por unidad experimental. Las variables evaluadas fueron: porcentaje de daño en el fruto por Edessa sp y Conotrachelus dubiae, número de botones florales y frutos cuajados, y peso y diámetro del fruto. Se observó que el tratamiento con Manejo Integrado de Plagas presentó menor daño de frutos por Edessa sp (6%) y C. dubiae (0.25%), mayor número de frutos cuajados (497) y mayor peso del fruto a la cosecha (10.2 g) que el tratamiento con manejo tradicional. Se puede concluir que la aplicación del Manejo Integrado de Plagas reduce el ataque de plagas y mejora los componentes productivos. PALABRAS CLAVE: camu camu, MIP, Conotrachelus dubiae, Edessa sp, biocidas ASSESSMENT OF THE INTEGRATED PEST MANAGEMENT OF Myrciaria dubia IN UNFLOODED SOILS OF THE UCAYALI BASIN, PERU ABSTRACTThe increase in areas for monoculture plantations of camu camu generates the proliferation of pests and herbivores that affect fruit production by more than 80%. This study evaluates the application of an integrated pest management technique which consist of applying cultural control of pruning and defoliation and monthly weeding, ethological control with yellow and entomological glue-traps, Biological control using aqueous extracts of the biocide plant Paullinia clavigera. We compared this management technique with the traditional management (MT) in the control of pests of camu camu plantations in upland soils. The experiment used a completely randomized design (CRD) with four replicates and four plants per experimental unit. The variables evaluated were: percentage of fruit damage by Edessa sp and Conotrachelus dubiae, number of flower buds and set fruits, and weight and diameter of the fruit. We observed that the treatment with integrated pest management presented significantly less fruit damage by Edessa sp (6%) and C. dubiae (0.25%); greater number of set fruits (497) and increased fruit weight at harvest (10.2 g) than the treatment with traditional management. We concluded that the application of integrated pest management reduces pests and improved productive components.
