Abstract
En el Manejo Integrado de Plagas (MIP), el método de Control Biológico acrecienta importancia y representa gran relevancia en el control de plagas. En este contexto el presente trabajo de investigación tuvo como objetivo evaluar la capacidad de predación de Cryptolaemus montrouzieri L., y su eficiencia sobre Pseudococcus longispinus L. en Vaccinium corymbosum, Chao (La Libertad). Para ello, en condiciones de laboratorio se determinó el nivel de predación de los estadios de larva I, larva II, larva III y larva IV, así como del estado adulto de Cryptolaemus montrouzieri L., sobre ninfa I, ninfa II, ninfa III y adulto de Pseudococcus longispinus L. Para determinar su eficiencia a nivel de campo los tratamientos consistieron en la liberación de cuatro núcleos de 250 individuos por hectárea de los estadios de larva II, larva III y del estado adulto y se consideró un área sin liberación del controlador biológico como testigo absoluto(T0). La capacidad de predación de Cryptolaemus montrouzieri durante todo el estado larval y adulto fue de 2214 individuos de Pseudococcus longispinus. Siendo el estado adulto y el estadio de larva III los que presentaron el mayor consumo con 269 y 1571 presas respectivamente. A nivel de campo todos los estadios de larva y el estado adulto evaluados presentaron similar eficacia en la regulación poblacional de Pseudococcus longispinus en arándano.
In Integrated Pest Management (IPM), the Biological Control method increases in importance and represents great relevance in pest control. In this context, the present research work aimed to evaluate the predatory capacity of Cryptolaemus montrouzieri L., and its efficiency on Pseudococcus longispinus L. on Vaccinium corymbosum, Chao (La Libertad). To do this, under laboratory conditions, the level of predation of the larva I, larva II, larva III and larva IV stages was determined, as well as the adult stage of Cryptolaemus montrouzieri L., on nymph I, nymph II, nymph III and adult of Pseudococcus longispinus L. To determine its efficiency at the field level, the treatments consisted of the release of four nuclei of 250 individuals per hectare of the stages of larva II, larva III and the adult state and an area without release of the controller was considered. biological as absolute control (T0). The predatory capacity of Cryptolaemus montrouzieri during the entire larval and adult stage was 2214 individuals of Pseudococcus longispinus. Being the adult state and the larval stage III those that presented the highest consumption with 269 and 1571 prey respectively. At the field level, all the larval stages and the adult stage evaluated presented similar efficacy in the population regulation of Pseudococcus longispinus in blueberries.
