Modes of light that contain topological defects such as screw dislocations can be focused into optical traps with interesting and useful properties. The way in which the intensity distribution within helical modes of light varies with topological charge is discussed, and new scaling predictions for their radial profiles that are consistent with experimental observations are introduced.

We collected anophelines every second week for one year from randomly selected houses in southwestern Ethiopia by using Centers for Disease Control (CDC) light traps, pyrethrum spray catches, and artificial pit shelter constructions to detect circumsporozoite proteins and estimate entomologic inoculation rates (EIRs). Of 3,678 Anopheles arabiensis tested for circumsporozoite proteins, 11 were p...

the main vector of malaria in europe and palearctic region is anopheles maculipennis complex. in order to determine the survival rate of an. maculipennis s.l. this study was carried out in garaboteh (zanjan province, iran) in july 2003. in this study anophelines were sampled for 31 consecutive days from five fixed animal shelters and five light traps. out of 24481 collected an. maculipennis s.l...

This study was undertaken to identify the phlebotomine fauna and species abundance in domiciliary and peridomiciliary (hen-house and guava-tree) environments, on a lake shore, a cultivated area of coffee and banana, and a forested area of Conceição da Aparecida municipality, southeastern the state of Minas Gerais, to provide information for the control and epidemiological surveillance of leishm...

Aedes albopictus is a potential West Nile virus bridge vector in Northern Virginia; however, information regarding its virus transmission dynamics is limited, as this species is not readily collected in existing traps. This study used 5 replicates of a 5 x 5 Latin square to evaluate the efficiency and effectiveness of 2 novel host-seeking mosquito traps (the BG-Sentinel and the Collapsible Mosq...

We aimed to monitor the species diversity and dynamics of number soybean pests using light traps with an original design develop protection systems against main phytophages. Traps lured 44 insects from eight orders 27 families. The capture 15 economically important phytophages was recorded—representatives various families: order Lepidoptera—Noctuidae, Crambidae, Erebidae, Geometridae; Hemiptera...

ABSTRACT. Sand flies are important vectors of cutaneous leishmaniasis, especially along coastal towns of northwestern Libya where an estimated 20,000 cases have occurred from 2004 to 2009. Host-seeking traps are an important tool for sampling sand fly populations and surveying the incidence of Leishmania major and L. tropica within a given population. We evaluated the capture efficiency of CO2-...
