Different types of aspirators for mosquito collections

Updated: Dec 8, 2020

The manual aspirators are integral to conduct mosquito research. Classical mosquito collections are made using mouth aspirators, which has a glass or polycorbonate collection tubing and a silicone tube to suck the air. It is the most simple, easy and economical way to collect mosquitoes for conducting various laboratory experiments. Two major drawbacks with this method are; really tiresome and entry of unwanted particles to human throat while performing mosquito collections in dusty or unhigenic surfaces.

Filter based classic aspirators

Recently, as a substitute to mitigate the negative effects of having a wire mesh between the silicon tubing and the glass collection tube, a HEPA or similar purpose material have been introduced. These filters helps stopping the entry of unwarranted foreign material into human throat thereby accomplishing harmless collections. The downside of these aspirators is sucking power; due to filters the free air flow is restricted and to do collections, it is mandates to put extra suction pressure to do a quick collections.

Improved mosquito aspirators with a collection chamber installed with dust/allergin filters

One of the disadvantages of the classic aspirators is the damages to the mosquitoes. The collected mosquitoes need to sucked frequently to keep them in the collection tube. This will exert unwanted pressure on the mosquitoes. When collection of multiple insects made they started becoming piling on one another fighting to be free and space. A new improved model has been introduced recently to address this issue. These aspirators has three parts: collection tube (acrylic or PP), collection chamber (polycorbonate) and sucking tube (silicone or regular latex tubing). The collection chamber has 1"*2.5" (inches) inner space. Due to presence of this chamber mosquitoes find it bit difficult to escape when pressure not available to hold then back in the place.

Mechanical aspirator Mechanical aspirators are great way to work with insects. It offers solutions to each and every issue that might have to be faced while using classical methods. It offers to collect insects from even a very harmful and unhygienic surfaces. Use of these aspirators is less tiring, convenient and made insect collections a quick task. The battery operated mechanical aspirators suck insects due to negative pressure. Once the insects are sucked into the collection chamber, blowing the insects into containers release them. The mosquitoes are released into mosquito containers safe transporting insects into the laboratory. There are several models and variants of mechanical aspirators are available. The most recommended mechanical aspirator is the one that can works on external power source i.e., mobile power bank 5v.
