TLDR
In this paper, the authors deployed a high-resolution entomological lidar to monitor a half-kilometer static transect positioned over rice fields outside a Tanzanian village.Abstract:
Lack of tools for detailed, real-time observation of mosquito behavior with high spatio-temporal resolution limits progress towards improved malaria vector control. We deployed a high-resolution entomological lidar to monitor a half-kilometer static transect positioned over rice fields outside a Tanzanian village. A quarter of a million in situ insect observations were classified, and several insect taxa were identified based on their modulation signatures. We observed distinct range distributions of male and female mosquitoes in relation to the village periphery, and spatio-temporal behavioral features, such as swarming. Furthermore, we observed that the spatial distributions of males and females change independently of each other during the day, and were able to estimate the daily dispersal of mosquitoes towards and away from the village. The findings of this study demonstrate how lidar-based monitoring could dramatically improve our understanding of malaria vector ecology and control options.read more

High Dynamic Range in Entomological Scheimpflug Lidars
TL;DR: In this article, the authors report count rates of 104 insects/minute up to 2 km range and demonstrate that smaller insects can be detected further away by long exposures and show consistency between the captured biomass size spectra.

Malaria hotspots explained from the perspective of ecological theory underlying insect foraging
TL;DR: It is proposed that the use of conventional vector control and malaria interventions, integrated with their intensified application targeting predicted hotspots, can be used to reduce malaria incidence in endemic and residual malaria settings.

The economic and social burden of malaria
TL;DR: There are multiple channels by which malaria impedes development, including effects on fertility, population growth, saving and investment, worker productivity, absenteeism, premature mortality and medical costs.

TL;DR: It is found that Plasmodium falciparum infection prevalence in endemic Africa halved and the incidence of clinical disease fell by 40% between 2000 and 2015, and interventions have averted 663 (542–753 credible interval) million clinical cases since 2000.

TL;DR: The findings show that the malaria mortality burden is larger than previously estimated, especially in adults, and there has been a rapid decrease in malaria mortality in Africa because of the scaling up of control activities supported by international donors.
