Abstract. Livestock grazing is the most important direct management impact on grasslands in upland areas of the UK. For phytophagous species, such as Lepidoptera, the impact is primarily through grazing altering the species composition and structure of the vegetation. However, specific impacts related to different grazing regimes are not well understood for this group of insects. Within a replicated controlled grazing experiment, nocturnal adult moths were sampled by light trapping in the fifth year after establishment. Sampling effort was standardised between the four grazing treatments by simultaneously using identical traps in each treatment. The highest‐intensity grazing treatment produced the lowest moth abundance and species richness. Ungrazed and low‐intensity sheep grazing treatments produced the highest moth abundance and species richness. Moths that feed exclusively on graminoids and moths that overwinter as larvae were disproportionately well represented in the ungrazed treatment. A sub‐set of species for which large declines have recently been documented in the UK were most abundant in the ungrazed treatment. However, they made up the largest proportion of the overall assemblage in the high‐intensity grazing treatment. Increased grazing inversely affects moth abundance and species richness. However, effects are not even across all moth species. An absence of grazing is likely to negatively affect the abundance of some moths, especially those that overwinter in the egg stage.

“…The 15 sites were sampled twice each, with one repeat in each of two rotations (mean interval between consecutive samples at the same site ± SD = 27.6 ± 9.9 d, N = 15 sites), resulting in a total sampling effort of 30 trap-nights (two trap-nights or 24 trap-hours per site). The sampling order of sites within each rotation was controlled to account for the fraction of the moon illuminated () and to avoid any systematic bias from the well-documented influences of weather on light-trap captures (Fry & Waring 2001, Spalding & Parsons 2004, Yela & Holyoak 1997). Catches were also restricted to periods without strong moonlight by avoiding nine nights around the full moon (Yela & Holyoak 1997), and weather conditions were recorded every hour during sampling.…”

Diversity and composition of Amazonian moths in primary, secondary and plantation forests

The response of tropical fauna to landscape-level habitat change is poorly understood. Increased conversion of native primary forest to alternative land-uses, including secondary forest and exotic tree plantations, highlights the importance of assessing diversity patterns within these forest types. We sampled 1848 moths from 335 species of Arctiidae, Saturniidae and Sphingidae, over a total of 30 trap-nights. Sampling was conducted during the wet season 2005, using three light-traps at 15 sites within areas of primary forest, secondary forest and Eucalyptus urograndis plantations in northern Brazilian Amazonia. The Jari study region provides one of the best opportunities to investigate the ecological consequences of land-use change, and this study is one of the first to examine patterns of diversity for a neotropical moth assemblage in a human-dominated landscape in lowland Amazonia. We found that the three moth families responded consistently to disturbance in terms of abundance and community structure but variably in terms of species richness, in a manner apparently supporting a life-history hypothesis. Our results suggest that secondary forests and Eucalyptus plantations can support a substantial level of moth diversity but also show that these forest types hold assemblages with significantly distinct community structures and composition from primary forest. In addition, the ability of these converted land-uses to support primary forest species may be enhanced by proximity to surrounding primary forest, an issue which requires consideration when assessing the diversity and composition of mobile taxa in human-dominated landscapes

“…It has been used in various types of ecological studies (Basset et al 1997;Campos et al 2006;Kulfan et al 2006;Hicks et al 2007), often in relation to phytophage -host-tree. However, with light trapping, done by using of automatic light traps allows the obtaining of valuable information about adults (Wolda et al 1992;Basset et al 1997;Szentkirályi 2002;Raimondo et al 2004;Spalding, Parsons 2004;Szabó et al 2007;Hirao et al 2008). Both methods may be combined in a survey and study of D. schmidtii populations at the same time:…”

Dioszeghyana schmidtii (Di󳺥ghy 1935), is forest species protected by European Union. Its distribution has been studied essentially by the use of light traps. However, its biology and habitat preferences are not sufficiently known and thus its habitats may be damaged by forest management. We suggest the beating method in order to collect larvae as an useful way to record and to survey D. schmidtii. Larvae of the species can be collected by beating branches of its host plants (Quercus and Acer species) in the lower canopy (below 3 m). Optimal survey time would be the second half of May and the first half of June. Differences between the larvae of D. schmidtii and 16 similar moth larvae, as well as, Tenthredinidae (Hymenoptera) species living at the same time on the same trees are described and figured in a key to identification. The method described in the paper allows one to identify larvae in the field. Results are discussed.
