Insects are a hyper diverse and ecologically important group. Their high diversity, however, presents challenges in sampling methodology, because rare species unreliably detected with low effort. However, the relationship between effort detections, critical for effective monitoring evaluation of population trends, is too seldom quantified. We sampled forest beetles 3 months 4-ha stand mixed dec...

Two species of Psilochalcis (Hymenoptera: Chalcididae) wasps occurring in the Great Basin region western United States were sampled from three locations central Utah (USA) over a two-year period using Malaise traps. Each location is composed four contiguous habitat types: pinyon/juniper (Pinus edulis or P. monophylla and Juniperus osteosperma), sagebrush (Artemisia tridentata), cheatgrass (Brom...

Bees are the main pollinators of native and agricultural plants. Identifying knowing these insects responsible for environmental service pollination is essential maintenance management in systems, especially a high diversity biome as Amazon rainforest. Some crops this region dependent benefited by wild pollinators, plants like guarana. To address methodological aspects monitoring bee diversity,...

BACKGROUND The aim of the study was to evaluate and compare the efficiency and practicality of seven trapping methods for adult phlebotominae sand flies. The results of this investigation provide information to determine the species composition and nocturnal activity pattern of different sand fly species. METHODS The study was carried out in both plain region (about 5km far from northeast) an...

There remains great uncertainty about how much tropical forest canopies contribute to global species richness estimates and the relative specialization of insect species to vertical zones. To investigate these issues, we conducted a four-year sampling program in lowland tropical rainforest in North Queensland, Australia. Beetles were sampled using a trap that combines Malaise and flight interce...
