Human activities have ledto global simplification of ecosystems,among which Neotropical dry forests are some of the most threatened.Habitat loss as well as edge effects may affect insect communities.Here,we analyzed insects sampled with pan traps in 9 landscapes (at 5 scales,in 100-500 m diameter circles) comprising cultivated field sand Chaco Serrano forests,at overall community and taxonomic order level.In total 7043 specimens and 456 species of hexapods were captured,with abundance and richness being directly related to forest cover at 500 m and higher at edges in comparison with forest interior.Community composition also varied with forest cover and edge/interior location.Different responses were detected among the 8 dominant orders.Collembola,Hemiptera,and Orthoptera richness and/or abundance were positively related to forest cover at the larger scale,while Thysanoptera abundance increased with forest cover only at the edge.Hymenoptera abundance and richness were negatively related to forest cover at 100 m.Coleoptera,Diptera,and Hymenoptera were more diverse and abundant at the forest edge.The generally negative influence of forest loss on insect communities could have functional consequences for both natural and cultivated systems,and highlights the relevance of forest conservation.Higher diversity at the edges could result from the simultaneous presence of forest and matrix species,although "resource mapping" might be involved for orders that were richer and more abundant at edges.Adjacent crops could benefit from forest proximity since natural enemies and pollinators are well represented in the orders showing positive edge effects.
