TLDR
In situ lidar classification of several insect families and their sexes based on their modulation signatures is demonstrated and how lidar-based monitoring of distinct mosquito activities could advance the understanding of vector ecology is demonstrated.Abstract:
Yearly, a quarter billion people are infected and a half a million killed by the mosquito-borne disease malaria. Lack of real-time observational tools for continuously assessing the unperturbed mosquito flight activity in situ limits progress toward improved vector control. We deployed a high-resolution entomological lidar to monitor a half-kilometer static transect adjacent to a Tanzanian village. We evaluated one-third million insect observations during five nights, four days, and one annular solar eclipse. We demonstrate in situ lidar classification of several insect families and their sexes based on their modulation signatures. We were able to compare the fine-scale spatiotemporal activity patterns of malaria vectors during ordinary days and an eclipse to disentangle phototactic activity patterns from the circadian mechanism. We observed an increased insect activity during the eclipse attributable to mosquitoes. These unprecedented findings demonstrate how lidar-based monitoring of distinct mosquito activities could advance our understanding of vector ecology.read more

TL;DR: In this paper, the authors use the latest climate simulations from the UK Earth System Model UKESM1 to understand feedbacks in fire, dynamic vegetation, and terrestrial carbon stores using the fire-enabled land surface model JULES-INFERNO, taking into account future scenarios of change in emissions and land use.

TL;DR: Lidar results from a Swedish forest with controlled bark beetle release event are presented, and the capability of lidar to simultaneously monitor both insects and a pheromone plume mixed with chemical smoke governing the dispersal of many insects is demonstrated, suggesting entomological lidar is a promising tool for monitoring bark beetles.

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.

The Economic Burden of Malaria
TL;DR: It is speculated about the mechanisms that could cause malaria to have such a large impact on the economy, such as foreign investment and economic networks within the country, and a second independent measure of malaria has a slightly higher correlation with economic growth in the 1980-1996 period.

Identification of Single Specimens of the Anopheles Gambiae Complex by the Polymerase Chain Reaction
TL;DR: A ribosomal DNA-polymerase chain reaction (PCR) method has been developed for species identification of individuals of the five most widespread members of the Anopheles gambiae complex, a group of morphologically indistinguishable sibling mosquito species that includes the major vectors of malaria in Africa.

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.
