ground beetles (carabidae) with more than 40,000 described species worldwide are one of the main generalist predator groups and have an important role in reducing pest population and enhancing biodiversity of agricultural and wild ecosystems. specimens from different agricultural and forest ecosystems in azadshahr region, golestan province, northern iran, using pitfall traps and light traps, be...

Since its introduction into the United States in the past 10 yr, soybean aphid, Aphis glycines Matsumura (Hemiptera: Aphididae), has been a damaging pest to soybean, Glycine max (L.) Merrill. During 2008 and 2009, fields in central and north central Iowa experienced pockets of high soybean aphid populations. Electroantennograms have shown that soybean aphid alatae are capable of detecting host ...

We report on a systematic survey of the ant fauna occurring in hardwood forests in the Great Smoky Mountains National Park. At 22-mixed hardwood sites, we collected leaf-litter ant species using Winkler samplers. At eight of those sites, we also collected ants using pitfall and Malaise traps. In total, we collected 53 ant species. As shown in other studies, ant species richness tended to declin...

We tested the effects of three vegetation management strategies for constructed treatmentwetlands on adult shore-ßy (Diptera: Ephydridae) successional occurrence and emergence in southern California. Before ßooding with efßuent from a nearby wastewater treatment plant, eight 0.1-ha research cells were randomly assigned to (1) control cells which were burned to reduce the abovegroundplantbiomass...

1 We compared standard multiple-funnel, modified multiple-funnel, intercept panel and canopy malaise (SLAM) traps with top and bottom collecting cups for their effectiveness (species richness, rarity, abundance) at capturing Cerambycidae in eastern North America. 2 Experiments were conducted in New York, Louisiana, Massachusetts and Georgia in 2011 and 2012. A combination of pheromones and host...
