Trap Catches of Dipteran Insects using Ultraviolet LED (Light Emitting Diode) and Water-pan Trap

Effects of flower abundance and colour on pan-trap catches

Subsampling of large light trap catches of Culicoides (Diptera: Ceratopogonidae).

Analyses of 2 light trap catches comprising 6,041 and 1,598 Culicoides showed that the reliability of subsampling such catches increased with subsample size, while the subsampling error decreased with an increase in the number of individuals per species present in a subsample. Subsamples comprising approximately 500 Culicoides are deemed sufficient for comparing population densities between sit...

Venus dye trap catches executioners

Tumor cells get primitive hen metastatic tumor cells migrate through connective tissue, they use proteases to chew a path for themselves. This finding led to the development of protease inhibitors as potential cancer therapies, but some animal and human clinical tests of these drugs have been disappointing. Wolf et al., reporting on page 267, may have found one reason why: when proteolysis is i...

NightLife: A cheap, robust, LED based light trap for collecting aquatic insects in remote areas

There are approximately one hundred thousand aquatic insect species currently known to science and this figure is likely a significant underestimation. The ecology of aquatic insect groups has been studied due to their role as bioindicators of water quality and in the case of Diptera, their role as vectors of disease. Light trapping targets emergent adults, using mercury vapour bulbs or actinic...

Curing efficiency of high-intensity light-emitting diode (LED) devices.

We evaluated the curing efficiency of 4 high-intensity light-emitting diode (LED) devices by assessing percentage of residual C=C (%RDB), surface microhardness (SM), depth of cure (DC), percentage of linear shrinkage-strain (%LS), and percentage of wall-to-wall contraction (%WWC). The light-curing units tested were a QTH light, the Elipar TriLight (3M/ESPE), and 4 LED devices - the Allegro (Den...
