“…Recent advances in sentinel surveillance of mosquito populations include the development of optical sensors that identify and classify insects based on their wing beat frequencies (WBFs) (Batista et al 2011, Chen et al 2014, Potamitis and Rigakis 2015, as well as male-focused traps that capture males by exploiting their attraction to female WBFs, the primary means of female identification and tracking for urban male Aedes spp. (Stone et al 2013, Johnson and Ritchie 2015, Balestrino et al 2016.…”

Aedes aegypti is a vector of many significant arboviruses worldwide, including dengue, Zika, chikungunya, and yellow fever viruses. With vector control methodology pivoting toward rearing and releasing large numbers of insects for either population suppression or virus-blocking, economical remote (sentinel) surveillance methods for release tracking become increasingly necessary. Recent steps in this direction include advances in optical sensors that identify and classify insects based on their wing beat frequency (WBF). As these traps are being developed, there is a strong need to better understand the environmental and biological factors influencing mosquito WBFs. Here, we developed new untethered-subject methodology to detect changes in WBFs of male and female Ae. aegypti. This new methodology involves directing an ultrasonic transducer at a free-flying subject and measuring the Doppler shift of the reflected ultrasonic continuous wave signal. This system's utility was assessed by determining its ability to confirm previous reports on the effect of temperature, body size, and age on the WBFs generated from acoustic or optical-based experiments. The presented ultrasonic method successfully detected expected trends for each factor for both male and female Ae. aegypti without the need for subject manipulation and potential impediment of natural flight dynamics due to tethering. As a result, this ultrasonic methodology provides a new method for understanding the environmental and physiological determinants of male and female WBFs that can inform the design of remote mosquito surveillance systems.

“…The latter one, to our point of view, opens new grounds as a deformable, slim sheet of polymer/acrylic light guides will allow tracking of flying insects inside various curved shapes of traps. b) In the new sensor, though the FOV increases by a factor 2-10 compared to a linear 1D array of diodes, a series of improvements in the circuit design result into a lower noise level than in [5]. c) In this study we send pulses at much higher rates (i.e.…”

“…The implications of this technology are discussed in view to embedding it in insect traps to count and classify flying-in insects based on the spectrum of their wingbeat [4]. A historical retrospection of optical methods applied to measuring insect movement is presented in [5] and the references therein. Various configurations of opto-electronic systems have been developed in the past to study the movement of insects [6][7][8][9].…”

“…Once triggered the light fluctuation is turned to an audio snippet, time-stamped and internally stored in the SD of the device as a permanent record. As in [5] this work is based on modulating-demodulating high frequency light pulses hitting the beating wings of the insect. However, in this work we introduce several novelties in the sensors' construction and offer a complete wingbeat recording system as well.…”

Recording and analysis of wildlife sounds with regard to monitoring biodiversity is a developing trend in ecology. Automatic audio-based units are commonly used to record field vocalizations of birds, bats, cetaceans and amphibians. The wingbeat of insects produces audible but feeble tones. Practical automatic recording units for the wingbeat of insects are still pending. In this work we present a complete system to record the wingbeat of insects based on large aperture optical sensors that turn the light fluctuations (caused by the partial occlusion of light from the wings) into sound. Wide apertures are useful when tracking the movement of fast flying insects and the full motion of the beating wing in the case of tethered insects. The system detects a wingbeat event, auto-triggers the recording process, time-stamps the event and stores the permanent record in-situ. When the sensor is inserted in an insectary it effortlessly produces massive datasets of wingbeat recordings. We discuss implications for novel studies that are impractical to carry out manually, as they involve large numbers of insects. We also suggest potential applications such as smart insect traps that count, recognize and alert for the presence of insects of economic and public health importance.

“…We have experience recording over a hundred thousand insect observations per hour [21], and species classification through modulation spectroscopy of insect wing beats has been demonstrated [11,[22][23][24]. Entomological lidar systems typically have a spatial resolution in the order of centimeters and a temporal resolution in the order of microseconds.…”

Background: In recent years, our group has developed electro-optical remote sensing methods for the monitoring and classification of aerofauna. These methods include active lidar methods and passive, so-called dark-field methods that measure scattered sunlight. In comparison with satellite-and airborne remote sensing, our methods offer a spatiotemporal resolution several orders of magnitude higher, and unlike radar, they can be employed close to ground. Whereas passive methods are desirable due to lower power consumption and ease of use, they have until now lacked ranging capabilities. Results:In this work, we demonstrate how passive ranging of sparse insects transiting the probe volume can be achieved with quadrant sensors. Insects are simulated in a raytracing model of the probe volume, and a ranging equation is devised based on the simulations. The ranging equation is implemented and validated with field data, and system parameters that vary with range are investigated. A model for estimating insect flight headings with modulation spectroscopy is implemented and tested with inconclusive results. Insect fluxes are retrieved through time-lag correlation of quadrant detector segments, showing that insects flew more with than against the wind during the study period. Conclusions:The presented method demonstrates how ranging can be achieved with quadrant sensors, and how it can be implemented with or without active illumination. A number of insect flight parameters can be extracted from the data produced by the sensor and correlated with complementary information about weather and topography. The approach has the potential to become a widespread and simple tool for monitoring abundances and fluxes of pests and disease vectors in the atmosphere.
