Evaluation role of some types of plant fertilizers toward leaf miners and its parasitoid on broad bean Vicia faba (L.)

Abstract

The role of four fertilizers type namely (biofertilizers, organic manure, compost el Wadi and chemical fertilizer) toward the population fluctuation of leafminers, Liriomyza spp. and its damage to snap faba bean were evaluated. The population fluctuation of leafminer Liriomyza spp and its' parasitoid increased in case of fertile soil more than unfertile one. The relation between the population fluctuation of leafminer parasitoid was positively affected by the population of leafminers. On other side, the results indicated that the growth parameters of fertile plant were recorded significant variation more than unfertile plant.
