Single-beam optical gradient force traps created by focusing helical modes of light are known as optical vortices. Modulating the helical pitch of such a mode's wave front yields a new class of optical traps whose dynamically reconfigurable intensity distributions provide new opportunities for controlling motion in mesoscopic systems. An implementation of modulated optical vortices based on the...

Photostimulated luminescence (PSL) and thermoluminescence (TL) from five L~2(1-~)Ce2~(Si04)0 &SO) crystals with different light outputs is reported. Optical irradiation into the Ce3+ absorption bands causes the appearance of a broad absorption band near 280 nm which is ascribed to Ce4+. In addition, a tail is observed extending beyond 700 nm. Optical irradiation into this tail (PSL) or heating ...

BACKGROUND The aim of the study was to evaluate and compare the efficiency and practicality of seven trapping methods 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. METHODS The study was carried out in both plain region (about 5km far from northeast) an...

The present paper reports for the first time the capture of wild Triatoma brasiliensis and Triatoma pseudomaculata by means of light traps in Brazil. We tested commercially available lighting devices powered by batteries to attract the bugs to a white piece of cloth in the field. Two main findings showed to be significant: first, the results presented here show that light traps can be used for ...

In this investigation, the species composition of sand flies, and their seasonality, nocturnal activity, sex ratio, and resting site, for implementation of future control measures, were surveyed in eastern (Gonda and Basti) Uttar Pradesh, India. Adult sand flies (2,893) were collected from internal and external sites by sticky and light traps. The sand flies were captured using light traps hung...

In recent years, a local, growing population of cutworm in agricultural fields with various plants such as vegetables, horticultural, and ornamental plants has been observed. The scope of our research covered the observation of two species of cutworms: Agrotis segetum (Schiff.) and A. exclamationis (L.), which are the most dominant species in Poland. Cutworms were monitored in the 2005–2009 sea...

The high proportion of cases of cutaneous leishmaniasis reported amongst residents in the city of Bandeirantes, in the state of Paraná, Brazil, led the authors to investigate the phlebotomine fauna in both urban and rural environments. The sandflies were captured with automatic light traps from 07:00 pm-07:00 am fortnightly in 11 urban peridomiciles from April 2008-March 2009 and monthly in thr...

The relatively large number of Culicoides midges (Diptera: Ceratopogonidae) that can be collected with a light trap makes it the most widely used tool for this purpose. However, the majority of these traps were originally designed for collecting mosquitoes. The evaluation and improvement of traps to increase their effectiveness in collecting Culicoides midges will unavoidably form part of resea...

Culicoides midges (Diptera: Ceratopogonidae), are involved in the transmission of various pathogens that cause important diseases of livestock worldwide. The use of insect repellents to reduce the attack rate of these insects on livestock could play an important role as part of an integrated control programme against diseases transmitted by these midges. The objective of this study was to d...

Keyword Index: Aedes albopictus, tire trap description, surveillance tool, Dominican Republic. With the introduction of Aedes albopictus (Skuse) into the Americas from southeast Asia and Japan (Hawley 1988), many surveillance tools originally used for Aedes aegypti Linn. programs were adopted to monitor the new invading species. In the continental U.S.A., conventional ovitraps (Fay and Eliason ...
