Comparison of thermoluminescence (TL) and scintillation light outputs with continuous gamma-ray excitation reveals that the concentration of deep hole traps in ceramic Lu2O3:Eu, tentatively attributed to anion Frenkel defects, is enhanced by reversible radiation damage. Shallow electron and hole traps are tentatively attributed to surface states at grain boundaries. Electrons in shallow traps s...

In Jun and Jul 2011 traps were deployed in Tuskegee National Forest, Macon County, Alabama to test the influence of chemical and visual cues on the capture of bark and ambrosia beetles (Coleoptera: Curculionidae: Scolytinae). The first experiment investigated the attractiveness of traps baited with different ratios of ethanol to methanol (0:100, 25:75, 50:50, 75:25, 100:0). No differences occur...

visceral leishmanisasis is endemic and zoonotic in several foci in ardabil province, north west of iran. the main objective of this study was to determine the natural promastigote infection of sand-flies in active seasons, during 1991-1995. sand-flies were caught by sticky traps, aspirator and cdc light traps from indoors and outdoors. altogether 2659 sandflies were dissected and identified. th...

The efficiency of miniature CDC light-traps in catching West African malaria vectors was evaluated during two rainy seasons in a village near Ouagadougou, Burkina Faso. Traps were employed both indoors and outdoors using human baits protected by an insecticide-free mosquito-net and different sources of light. Indoors, light from incandescent bulbs increased the catch of Anopheles gambiae s.l. (...

We analyze doubly magic trapping of Cs hyperfine transitions including previously neglected contributions from the ground state hyperpolarizability and the interaction of the laser light and a static magnetic field. Extensive numerical searches do not reveal any doubly magic trapping conditions for any pair of hyperfine states. However, including the hyperpolarizability reveals light intensity ...

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...

Lighted Centers for Disease Control and Prevention (CDC) light traps were baited with carbon dioxide (CO2) produced from three different sources to compare the efficacy of each in collecting phlebotomine sand flies in Bahrif village, Aswan Governorate, Egypt. Treatments consisted of compressed CO2 gas released at a rate of 250 ml/min, 1.5 kg of dry ice (replaced daily) sublimating from an insul...

A study to evaluate the use of light-emitting diodes (LEDs) as an attractant for phlebotomine sand flies at two animal pens in a livestock area in Brazil was performed. Light-suction traps were operated overnight with the following light sources: green, blue, and incandescent (control) lights. In total, 22 individual collections were made at each site and 44 with each trap type. In total, 2,542...

Two new species of Myrmedonota are described from Mexico. Illustrations and a distribution map are provided, as are keys to identify Myrmedonota known from the Nearctic and Neotropics. Specimens were collected by means of mercury vapor light traps or flight interception traps.
