We investigated the link between farmer practices, arthropod diversity, and yield on coffee farms in the Tarraz˙ region of Costa Rica. Using pitfall traps and malaise traps, we characterized the diversity of Coleoptera, Diptera, Hymenoptera, and Araneae on a range of farms that spanned a range of farmer practices. In particular, we looked at the relationship between herbicide use, fertilizer use, incorporation of shade-trees, and diversity of arthropods. We discuss the utility of using these taxa in assessing biodiversity, and also the management implications of our results for the coffee-growing cooperative.
