Selecting and breeding colonies with high levels of hygienic behavior has become a feasible and ... -
Fruit infestation patterns by Anastrepha fraterculus and Ceratitis capitata reveal that cross-recognition does not lead to complete avoidance of interspecific competition in nature
Devescovi, Francisco; Liendo, María Clara; Bachmann, Guillermo Enrique; Bouvet, Juan Pedro; Milla, Fabian Horacio; Vera, María Teresa; Cladera, Jorge Luis; Segura, Diego Fernando (Wiley, 2015-08)1. The avoidance of parasitized or infested hosts, which is a common phenomenon in parasitic wasps and phytophagous insects, may act both intra- and interspecifically. Most studies on chemically-mediated avoidance of ... -
