“…Whilst Ae. albopictus males may be active during the whole day, the greatest level of activity has been observed immediately after the dark-light transition in the field (Delatte et al, 2010) and in the laboratory (Boyer et al, 2013;Wilkinson et al, 2014). In the presented study, traps were activated following the protocol of Lacroix et al, (2009a); every day before the 1st peak of activity of Ae.…”

“…This was performed 1 h before sunset when Ae. albopictus activity is reduced (Wilkinson et al, 2014), in order to minimize bias in the 'escape' dispersal during release. Four MRR experiments were performed in different seasons in order to gauge seasonal variation in population densities: the first release begun in mid-summer (weeks 11-13) in March 2010, the second and third experiments were in June (weeks 22-25) and September, (week 35-37), in the beginning and at the end of austral winter, respectively, and the last experiment took place in November-December during the period of greatest Ae.…”

Effects of low-powered RF sweep between 0.01-20 GHz on female Aedes Aegypti mosquitoes: A collective behaviour analysis

There are many products claiming to be an electronic solution towards repelling mosquitoes. Several reviews were published in debunking these claims. However, there is a lack of a systematic study on effects of electromagnetic (EM) or more specifically, radio frequency (RF) waves against mosquitoes due to the conclusions made in those years. Therefore, we attempt to establish a fundamental study on female Aedes Aegypti (Linnaeus) mosquitoes by quantifying the collective behavior of the mosquitoes against a continuous stream of low-powered RF signals via a broadband horn antenna using image processing methods. By examining the average lateral and vertical positions of the mosquitoes versus frequency and time, the data shows negligible consistency in the reactions of the mosquitoes toward the different frequencies ranging from 10 to 20,000.00 MHz, with a step of 10 MHz. This was done by examining 33 hours of spatiotemporal data, which was divided into three sessions. All three sessions showed totally different convolutions in the positions in arbitrary units based on the raster scan of the image processing output. Several frequencies apparently showed up to 0.2–70% shift in both lateral and vertical components along the spectrum, without repeatability for all three sessions. This study contributes to the following: A pilot study for establishing the collective effects of RF against mosquitoes, open-source use, and finally a low-cost and easily adaptable platform for the study of EM effects against any insects.

“…We employed the method of tracking by the minimization of position change (Nearest Neighbor Algorithm), where an optimal candidate assignment is made based on a greedy search technique (i.e. Hungarian Algorithm)21. Single view imaging results in several scenarios where multiple objects are overlapped especially in the longitudinal direction.…”

Drosophila is an excellent model organism towards understanding the cognitive function, aging and neurodegeneration in humans. The effects of aging and other long-term dynamics on the behavior serve as important biomarkers in identifying such changes to the brain. In this regard, we are presenting a new imaging technique for lifetime monitoring of Drosophila in 3D at spatial and temporal resolutions capable of resolving the motion of limbs and wings using holographic principles. The developed system is capable of monitoring and extracting various behavioral parameters, such as ethograms and spatial distributions, from a group of flies simultaneously. This technique can image complicated leg and wing motions of flies at a resolution, which allows capturing specific landing responses from the same data set. Overall, this system provides a unique opportunity for high throughput screenings of behavioral changes in 3D over a long term in Drosophila.
