b a ckground: the aim of the study was to evaluate and compare the efficiency and practicality of seven trappingmethods 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. m e t hods: the study was carried out in both plain region (about 5km far from northeast...

Four types of commercial mosquito control traps, the Mosquito Magnet Pro (MMP), the Sentinel 360 (S360), the BG-Sentinel (BGS), and the Mega-Catch Ultra (MCU), were compared with a standard Centers for Disease Control and Prevention (CDC) light trap for efficacy in collecting phlebotomine sand flies (Diptera: Psychodidae) in a small farming village in the Nile River Valley 10 km north of Aswan,...

Abstract In the Anthropocene, planet is warming and global biodiversity, including of insects, being lost at an unprecedented rate. One largely urban sustainability solution, shifting to energy-efficient, light-emitting diode (LED) bulbs on outdoor lighting, has impacts insects that are inadequately understood, especially in tropics brightly lit cities. Working Singapore—a highly urbanised ligh...

OBJECTION The aim of this study is to determine the effect of clothing and the environment on human exposure to ultraviolet light. METHODS The ultraviolet (ultraviolet A and ultraviolet B) light intensity was measured, and air quality parameters were recorded in 2014 in Beijing, China. Three types of clothing (white polyester cloth, pure cotton white T-shirt, and pure cotton black T-shirt) we...

We compared the effectiveness of light traps and plankton tows for sampling brachyuran crab larvae in Bartlett Cove, Glacier Bay, Alaska, U.S.A. during three nights each in July and August 2001 and June, August, and September 2002. Proportions of species and stages were used to compare larvae caught by light traps and plankton tows. Absolute numbers of larvae are difficult to compare because of...

a r t i c l e i n f o Keywords: Barrier dielectric Vacuum ultraviolet radiation Low-k dielectrics Back end of the line The response of SiN, N-SiC, O-SiC, and SiC dielectrics of varying thickness deposited on Si substrates to irradiation with vacuum ultraviolet (VUV) was compared. The resulting charge was evaluated by measuring the surface potential on the dielectrics after irradiation with 9.5 ...

Adult mosquito collections were conducted for 12 weeks in two residential areas in Kuala Lumpur. The CDC light traps were compared using dry ice and yeast as sources of carbon dioxide attractants for mosquitoes. The efficacy of the dry ice baited trap was significant over yeast generated CO2 trap. The predominant species obtained were Culex quinquefasciatus, Stegomyia albopicta and Armigeres su...

a survey was conducted to study the fauna of the subfamily ophioninae (hymenoptera: ichneumonidae) in southern iranian provinces of fars and hormozgan. the specimens were collected using malaise traps, light traps and sweep nets from a variety different habitats between 2011 and 2013. a total of twelve species of three genera (enicospilus stephens; ophion fabricius and eremotylus forster) were ...

lithium disilicate nano-powders were synthesized via a mild condition hydrothermal reaction at 180 ºc for 48 and 72 h with a non stoichiometric1:2 li:si molar ratio in naoh aqueous solution using li2co3 and sio2.h2o as raw materials. the synthesized materials were characterized by powder x-ray diffraction (pxrd) technique and fourier transform infrared (ftir) spectroscopy. the xrd data showed t...
