Landscape effects on insect pests of Dracaena marginata and their associated natural enemies in Costa Rica
This study examined how the landscape in which D. marginata is embedded affected the abundance and distribution of these three insect pest groups and their associated natural enemies. In order to evaluate the effect of the macro landscape on crop pest abundance, different landscape metrics were evaluated at six spatial scales from local to broad scale. Insect groups showed different responses at different spatial scales. While leafhopper egg abundance was more sensitive in terms of their correlations with different land uses and metrics
