Parasitoid diversity and parasitism rates in Pampean agricultural mosaics are enhanced by landscape heterogeneity

Agricultural intensification affects negatively on landscape heterogeneity, biodiversity, biotic interactions and the associated ecological functions. Here, we describe the structure of herbivore–parasitoid interactions by analysing the rates of parasitism and their variability in relation to landscape heterogeneity. Phytometer traps ( Commelina erecta L.) infested with a specific leaf miner fly ( Liriomyza commelinae Walker) were used to...
