title: Entomopathogenicity of native bacteria from Anastrepha fraterculus and Ceratitis capitata against the pest Phyllocnistis citrella.
abstract: In Piura (Peru), the pest Phyllocnistis citrella Stainton damages the photosynthetic rate and new bud production of Citrus aurantiifolia Swingle (sweet lemon), decreasing the yield, productivity and commercial price of its fruit. Biological control was evaluated through the crossed effect of bacteria obtained from pests (Anastrepha fraterculus Wied., Ceratitis capitata Wied. and Rhynchophorus palmarum L.) that are pathogenic against their original host species. Enterobacter cloacae (Jordan) Hormaeche & Edwards and Serratia marcescens Bizio (from A. fraterculus and C. capitata) and Pseudomonas mendocina Palleroni (from R. palmarum) were used against P. citrella. The bacterial strains were inoculated into its food and the accumulated mortality was evaluated. Larvae of P. citrella treated with P. mendocina had the highest mortality (66.7%). These bacterial species were entomopathogenic against the original source pest in laboratory and greenhouse bioassays, and this result widens the pathological activity range of these bacterial species.
