Portable mosquito olfaction action reaction measuring device

Technical Field

The utility model relates to the field of biotechnology, especially, relate to a portable mosquito sense of smell action reaction survey device.

Background

Currently, there are a large number of people facing the threat of insect-borne infections, which constitute a major part of the human vector burden of transmitting diseases. Mosquitoes can transmit diseases such as malaria, dengue fever, japanese encephalitis, yellow fever, west nile fever and the like. Many countries or regions are affected by the frequent and periodic dengue epidemics, with a large number of cases of infection and symptomatic cases each year. For example, 2020 has statistically received about 2.41 million malaria cases and 62.7 million deaths due to malaria. Therefore, mosquito control is an important task in controlling mosquito-borne infectious diseases.

In nature, the mosquito's blood-sucking is used to breed offspring and supply energy to itself, a process that indirectly leads to the transmission of mosquito-borne diseases. For example, human mosquitoes such as Aedes albopictus and Aedes aegypti, target the host for the corresponding blood-sucking action using host-derived volatile compounds, most of which are produced by skin bacteria. Several studies have been shown to date to correlate skin bacteria with mosquito-localized host behavior. The volatile substances produced by human skin bacteria give it a unique odor, which is one of the reasons for the difference in human attractiveness to mosquitoes. For this reason, it is contemplated to utilize the human skin microflora to modify odor characteristics, prevent mosquito bites, and thereby prevent mosquito-mediated disease from occurring and circulating. Screening target skin microorganisms with the attraction effect on mosquitoes needs to test the mosquito attraction capability of different individuals.
