Light traps have been used widely to sample insect abundance and diversity, but their performance for sampling scarab beetles in tropical forests based on light source type and sampling hours throughout the night has not been evaluated. The efficiency of mercury-vapour lamps, cool white light and ultraviolet light sources in attracting Dynastinae, Melolonthinae and Rutelinae scarab beetles, and...
We compared 6 adult mosquito traps for effectiveness in collecting Aedes albopictus from suburban backyards with the goal of finding a more suitable surveillance replacement for the Centers for Disease Control and Prevention (CDC) light trap. Trap selection included 2 commercial propane traps (Mosquito Magnet Professional trap and Mosquito Magnet Liberty trap), 2 Aedes-specific traps (Fay-Princ...
We evaluated the effectiveness of commercially available light traps and sticky traps baited with chemical light sticks for the collection of phlebotomine sand flies. Evaluations were conducted at Tallil Air Base, Iraq, in 2003. In an initial study, a Centers for Disease Control and Prevention (CDC)-style trap with UV bulb collected significantly more sand flies than did an up-draft CDC trap, a...
We study collisional loss rates due to spin-exchange collisions in very-low-intensity Rb magneto-optical traps. The loss rate exhibits an unpredicted intensity dependence for low intensities, accounting for a large disparity between loss rates observed in light-force traps and magnetically confined Bose condensates. Possible collision mechanisms considered include light-altered collision phase ...
Despite a control program, malaria incidence in Yunnan has increased and knowledge of vector bionomics is needed for efficient control. Multi-drug resistant Plasmodium falciparum necessitates alternatives to human landing catches as a means of studying vectors. Therefore CDC light traps with UV or ordinary incandescent bulbs were tested for 57 trap nights. 2,703 mosquitos were caught, including...
We investigated mosquito sampling techniques with two types of traps and attractants at different time for trapping potential vectors for Rift Valley Fever virus. The study was conducted in six villages in Ngorongoro district in Tanzania from September to October 2012. A total of 1814 mosquitoes were collected, of which 738 were collected by CDC light traps and 1076 by Mosquito Magnet trapping ...
A simple and relatively cheap locally-assembled light trap was used to sample pre-settlement fish larvae in the Malindi Marine Park, Kenya, for two years. The trap was assembled locally using a water dispenser bottle, plastic bottle necks, buckets, 12V rechargeable alkaline batteries and a diver’s dry box. The light unit consisted of a 12 V rechargeable alkaline Jacob’s battery that powered a 1...
Field studies were conducted in the Upper Rhine Valley to determine the responses of mosquitoes to CDC traps baited with either CO2, octenol, light or paired combinations of these. Among eight mosquito species caught, the attractant effect on trap catches was studied in the four most abundant: Aedes vexans, Ae. rossicus, Ae. cinereus and Culex pipiens. Traps baited only with light or octenol ca...
This paper is aimed at introducing a new approach to estimate the density of Brown Plant Hoppers (BPHs) at provincial scale. The model is based on the topology of a light-traps network (to gather the information about the BPHs) of a province. The BPHs density is determined based on Unit Disk Graph technique where each light-trap becomes a vertex and the edges reflect the relations on the mutual...
